What is a Belt Driven Linear Actuator

A belt-driven linear actuator is a device that translates rotary motion to linear motion via a timing belt connected to two circular pulleys. This type of actuator operates under the same principles as the conveyor belt system. Belt-driven actuators are generally preferred for applications with lower loads that require longer stroke lengths and higher speeds.

Construction of a Belt-driven Linear Actuator

The timing belt of a belt-driven actuator is typically constructed of a fiber-reinforced elastomer for non-demanding requirements or other material such as steel-reinforced polyurethane for more heavy-duty applications.

These types of actuators have a distinct advantage since manufacturers can build them at virtually any length. Belt drive actuator designs come in either an external, trapped, or internal belt arrangement. With standard accessories, the linear axes can be easily combined to create multi-axis systems.

Types of Belt-driven Linear Actuator

Belt-driven actuators come in a range of different configurations, allowing engineers to select easily available standard models, ready-to-use plug-and-play models, and custom-build models that allow for an extensive range of configurations.

Standard Belt-driven Linear Actuators

Standard belt-driven actuators come in stock travel lengths and offer several commonly configured options. These systems are readily available for fast delivery while still providing top-notch quality for a range of applications.

Plug-and-Play Belt-driven Linear Actuators

Plug-and-play belt-driven actuators come with automation functionality out of the box. Each unit comes complete with an actuator/belt drive, electric motor, and control system or device. These systems work well for research and laboratory applications, as well as university and educational robotics.

Custom Belt-driven Linear Actuators

Custom belt-driven actuators offer similar features as standard models. However, users can give custom specifications and requirements to best suit their application.

How to Use a Belt-driven Linear Actuator 

Belt-driven linear actuators are used where linear motion is required. From printers and valve dampers to industrial machinery and micro medical applications. Today, belt-driven linear actuators are more commonly used in vehicles to open doors, trunks, roofs, etc.

What is an Aircraft Actuator

Aircraft actuators are devices that can transmit and redirect one form of motion energy to another. The source of energy may be electric, hydraulic, or pneumatic. Actuation systems have many critical applications in the aviation industry. They’re used to operate everything from cargo bay doors and landing gear to engine components and flight control surfaces.

Aerospace technology is in a constant state of evolution with manufacturers and operators working to make aerospace equipment more efficient, streamlined, and cost-effective. For aerospace actuator systems, it’s crucial that they can withstand conditions such as strong vibrations, cold, and heat. They also need to be able to achieve very high dynamic forces yet be lightweight and fit into tiny spaces. 

Different Types of Actuator

Electro-hydraulic Actuators 

Electrohydraulic actuators combine the low infrastructure costs and simplicity of an electrical power supply with the mechanical failsafe capability and high operating speed of hydraulic or fluid-powered actuation systems. 

They’re a modular combination of a hydraulic actuator, a power unit supplying electric power to a hydraulic pump and motor, and a dedicated electric or electromechanical control system to control the actuator functions. They come in handy where only an electric power supply is available and mechanical failsafe action is crucial.

Electro-hydrostatic Actuators 

Electrohydrostatic actuators combine design elements from electric and electrohydraulic actuators. These systems convert electrical power into localized hydraulic power for flight control. They typically include their own hydraulic pump, eliminating the need for separate pumps and tubing. This results in a simpler system architecture that improves reliability and safety.

Electro-mechanical Actuators 

A growing interest in sustainable, energy-efficient technology in recent decades has encouraged the shift from traditional hydraulic systems to electromechanical actuators. These systems convert electricity to mechanical force, offering the strength of an aircraft hydraulic actuator with more precise movement and motion control. They feature simple designs and computerized control systems for enhanced control, reliability, and improved fuel efficiency.

In general, electromechanical actuators offer several benefits, including:

Compact: They have a smaller footprint than their hydraulic and pneumatic counterparts, so they require little space.

Precise: Electromechanical actuators can be more easily controlled for better performance.

Energy-efficient: Electromechanical actuators use less energy than pneumatic or hydraulic actuators.

Low maintenance: The design simplicity of electromechanical actuators makes them easier and cheaper to maintain.

Lightweight: With few components and light parts, electromechanical systems are lighter than other types of actuators, reducing the load on the aircraft and improving fuel efficiency.

Application and Capabilities of Aircraft Actuators

Airplane actuators are integral to many critical aircraft functions. Advances in aerospace actuation systems have been a key player in making aircraft more economical, more maneuverable, and faster. Common applications of these systems include:

●      Flaps

●      Thrust reversers

●      Visual guidance systems

●      Gimbals actuator

What Is a Miniature Linear Actuator?

You may be surprised to know that you interact with a miniature linear actuator in everyday machinery without knowing it. A micro linear actuator is vital for many motion control systems to move and control objects. 

Miniature actuators can be mechanical, electric, hydraulic, or pneumatically powered. Most of them consist of a basic construction with a base plate, runner with dual guides, and a stator. They work similarly to standard linear actuators, but miniature actuators are ideal for small spaces that need a significant payload. 

Are you ready to learn more about a tiny linear actuator’s purpose, use, and function? If so, consult the brief guide below.

Miniature Linear Actuators

Dimensions of Miniature Linear Actuators

A small linear actuator body is usually between 150mm and 1500mm. The short frame gives it a compact structure and convenient installation abilities for various functions. 

Because of the small linear actuator’s body size, they also have a micro stroke range. The stroke length can range from a few millimeters up to 50mm. Though the mini linear actuator has shorter strokes and a smaller size, it doesn’t produce as much force as a traditional linear actuator.

How Miniature Linear Actuators Work

Though several methods will power miniature linear actuators, most of them run on electricity. AC/DC electric motors of varying stroke lengths convert rotary motion to a linear one. In other words, the motors enable the actuators to push or pull in a straight line. 

Electric motors usually have a high-speed rotation. However, helical gearboxes slow the rotation speed to increase the actuators’ torque. A slower pace generates a greater torque, which helps a lead screw turn to generate the linear motion of the actuators’ drive screw or nut. Reversing the motors’ rotation direction also reverses the linear movement of the micro actuator.

Different Miniature Linear Actuator Applications

Linear actuators have a long history, with the agricultural industry being one of the first to use the component for farming equipment. Now, almost every industry uses linear actuators. 

Miniature actuators are no different. You can incorporate them in any application that needs linear motion but has weight or space restrictions, including the following.

Robotics

Micro linear actuators are essential for robotics, whether the machinery is for robotic manufacturing or robotic competitions. Actuators and motors control every movement. For instance, an actuator within a gripper arm communicates with sensors to perform a clamping motion using the appropriate amount of force.

Automotives

The car manufacturing industry often uses robotics to build vehicles. However, cars and trucks also contain miniature linear actuators to perform various functions, such as powering doors and moving windows up and down.

Home and Office

You can find a miniature linear actuator in many parts of your home and office. For instance, fold-up beds and tables you use as a space-saving solution incorporate actuators to move the furniture pieces. You can also find mini actuators in automatic recliners and remote-controlled consoles that push the TV out for better viewing.

Linear Actuator Lift System

There’s a chance you’ve seen a linear actuator system as they exist in many industries, from farming to hospital applications. Linear actuators are motors that transfer rotational energy to linear movements, working only in one direction and moving across in a straight line. How much can a linear actuator lift? Keep reading to find out.

Linear Actuators

linear lift system

How Linear Actuators Work

Linear actuators maintain pushing and pulling motions as motors spin. The continuous motion transfers the rotational motion of a linear lift system into lifting and dropping movements, making processes that require significant manpower much easier and more effective than hydraulic systems. In addition to raising motions, linear actuators can translate rotational motions into other automated actions.

How Much They Can Lift

How much can a linear actuator lift? The answer to this question varies depending on the actuator but ranges from as little as 15 lbs to up to 2,000 lbs. It’s necessary to choose a linear lift that provides the ideal amount of force and lifting power for your planned application.

To calculate how much a linear actuator can lift, you must use the following equation to determine the linear actuator force: 

T = WL μ cos(??) + (WL/386.4) * (v/ta) + WL sin(??) + Fk

Be sure you know all factors going into actuator lift calculations so they are accurate. You’ll also need to understand friction, applied force, acceleration, and gravity to calculate how much a linear actuator can lift.

Different Linear Actuator Applications

NASA’s Mars Rover

The NASA Mars Rover contains a variety of actuators that power moving processes on the machine. Actuators power the wheels that move it along the red planet’s surface. Additionally, actuators are active in the sample collector, which requires lifting motions and more.

Cars

Vehicles also require actuators for movement. Cars are full of actuators, including everything from adjustable seats to windshield wipers. When you activate mechanical processes such as rolling the windows up and down, actuators are also at work. Additionally, changing your car’s tire involves an actuator in your car jack tool.

Robots 

Robots have many moving parts that require actuators to complete each motion smoothly. A robot’s limbs, head, and eyes need actuators to perform repetitive walking motions, pick up objects, and more.

Movies

Movie sets use actuators to trigger events in scenes without needing hands-on involvement that could lead to a dangerous situation. Producers can rig props with lift actuator kits to get them to move during filming without risking bodily harm.

iPhone

An actuator inside your iPhone controls your device’s vibration function when you receive a call or notification. A motor in your phone activates the actuator to run at a certain speed, resulting in the fast pace of your iPhone’s vibration setting.

Choose the Best – Electric Actuator vs. Hydraulic Actuator

Actuators are systems that convert energy into torque to move components in various equipment. Even if you’re unfamiliar with actuators, you encounter them daily in machines like vehicle brake lines, industrial robots, and cell phones. The motions that actuators produce can be linear (straight lines) or rotary (revolving on an axis).

Actuators get their power through several means, including electricity or a hydraulic system. Though they each have advantages and disadvantages, people tend to lean more toward electric over hydraulic actuators. Still, it’s best to have all the facts about linear actuators to determine which variety will suit your needs best.

What Is an Electric Actuator?

A linear electric actuator uses electricity from a motor to generate power. When electricity flows through the system, the motors rotate a lead screw with a nut on a thread. The direction in which the nut moves on the line depends on the direction the screw turns.

Advantages and Disadvantages

If you need an actuator with both speed and accuracy, it’s best to go with an electric over a hydraulic linear actuator. These systems can function at up to 80% efficiency with the ability to stop in any position.

The units tend to be small, require little maintenance, and have no external components. Many of them also have fail-safe brakes called acme screw units to initiate self-locking if the motor loses power.

A significant drawback to electric linear actuators is the cost. Their design, efficiency, and construction usually mean a higher upfront cost. These actuators are also not ideal for hazardous areas or continual running because they can overheat.

What Is a Hydraulic Actuator?

Unlike an electric actuator, the hydraulic version does not rely on an electric motor for energy. Instead, a hydraulic actuator gets its power from hydraulic fluid consisting of various oils. The presence of the liquid creates pressure that forces cylinders in the system to move in straight lines.

Advantages and Disadvantages

Hydraulic actuators are incredibly powerful with high load capacities, making them the ideal system for high-force applications. They function well under intense pressure. The hydraulic fluid responsible for creating movement is incompressible so that the actuator can hold an impressive amount of force.

Unfortunately, the presence of hydraulic fluid means these actuators are prone to leaks. They require a lot of maintenance and plumbing to ensure that the systems are in good condition. The linear actuators have a decent speed, but accurately controlling them can be challenging due to the periodic jerking motion that occurs when it shifts from being still to moving.

How Electric Actuators Are Better Than Hydraulic

If you’re wondering if you should choose an electric over a hydraulic actuator, it’s best to remember that both options have their purposes in various industries, despite their drawbacks. However, electric actuators are a favorite for many due to their precision, safety, small size, and speed.

Though some businesses find hydraulic actuators appealing due to their low upfront costs, they could spend more on routine maintenance and repairs for leaks and numerous external components. It costs more to install an electric actuator, but the installs are quick, and the units don’t require much care.

High Speed Linear Actuators

high speed linear actuator

Creative Motion Control is proud to stock the PA-15 High Speed Linear Actuator. This overview will
describe high speed linear actuators like the PA-15, how they work, and why they are vital part in
modern industry.

What Is an Ultra High Speed Linear Actuator?

An actuator is a component in a device that makes a particular kind of motion happen. Actuators are
usually part of a larger system that includes sensors, structural components, and elements that interact
with the world in a particular way.
Different types of actuators produce different types of motion. A linear actuator produces motion in a
straight line and is appropriate for use when transferring various kinds of energy, such as rotational
energy, into linear motion.
Electric elevators and motorized wheelchair lifts use linear motion, so they rely on linear actuators. A
typical car jack is an example of a mechanical linear actuator. It converts the rotational motion provided
by the user into energy that moves a vehicle up or down. High speed linear actuators are typically used
when lighter loads need to be moved at higher speeds.
The P-15 ultra high speed linear actuators can achieve speeds as high as 9 inches per second, making it
suitable for applications that require rapid movements such as sorting and movements of a robotic arm.

Important Features of a High Speed Heavy Duty Linear Actuator

An actuator must have a mechanism to obtain energy. For example, a car jack’s lever connects to a gear
that transfers energy to the lifting element. In electric linear actuators, an electrical motor typically
rotates a gear. For actuators driven by gears, the gear size and thread width influence the function.
Consider the gears on a bicycle or in a car’s transmission.
A linear actuator must have a component that is capable of moving in a straight line, from side to side,
or up and down.
High speed linear actuator must typically be mounted securely to a stable structure so that the actuator
itself remains fixed in place while in operation. In some cases, like with a car jack, the weight of the
actuator keeps it stable. However, for precision control, mounting and other stabilization processes might be necessary.

Applications of a Linear Actuator (High Speed)

Recent trends toward automation and the development of the Internet of Things (IoT) have allowed the
digital world to have a direct physical impact. Automated factories, robot surgery, autonomous vehicles,
and several other systems operate under computer or computer-assisted control. Software must be able
to move real-world objects precisely and rapidly to accomplish many tasks. Here are just a few examples
of practical applications of high speed linear actuator technology.
● NASA’s rovers depend on actuators for precise control of sensors and instruments for analyzing
mars, asteroids, and other locations in space.
● In robot and remote surgery, linear actuators generate precise movements of surgical
instruments.
● The United States Postal Service uses linear actuators for high-speed automated sorting of mail.

The Power Source of a High Speed Linear Actuator (12V)

Actuators are often powered by electricity but can be powered by other energy sources, such as steam
or compressed gas. Piezoelectric actuators generate linear motion by using specialized materials that
produce mechanical energy (in other words, they push) in response to an electrical current.
The P-15 High Speed Linear Actuator uses a 12V power source so that it can run on a conventional U.S.
power outlet, eliminating the need for adaptors, transformers, or alternative sources of power.

Generation and Transmission of Rotational Energy in a High
Speed 12 Volt Linear Actuator

Linear actuators can convey rotational energy in different ways. For example, gears and belts can
transmit rotational energy. Gear-driven actuators are called rack-and-pinion actuators, with pinion being
another word for gear.
The P-15 High Speed Linear Actuator uses a 12 volt DC motor that imparts energy to a steel alloy gear,
which generates rotational energy that must be converted into linear motion. The motor has a 20% duty
cycle, meaning it can be on up to four minutes within a twenty-minute time frame.

Conversion of Rotational Energy to Linear Energy in a High
Speed 12 Volt Linear Actuator

For a linear actuator to function, it must effectively generate linear motion of some component from the
rotational movement of the belt or gear.
In the rack-and-pinion actuator, a gear (the pinion) contacts a linear structure with cogs called the rack.
As the gear turns, it slides the rack sideways.

A lead screw linear actuator consists of a threaded screw and a nut that encircles the screw. As the nut
rotates, the screw moves relative to the nut and anything attached to it. In some actuators, the nut
moves sideways, and the screw is fixed. In others, the nut is fixed, and the screw moves.
In roller screw actuators, rollers are placed between the screw and the nut surfaces to reduce friction. In
ball screw actuators, ball bearings are placed in grooves between the screw and the nut to produce the
same effect.
In the PA-15, the linear motion is achieved by the motion of a screw, like in the previous examples.

Mounting of High Speed High Force Linear Actuators

There are two common ways to mount an actuator: stationary mounting and dual-pivot mounting.
Stationary mounting is particularly suitable for situations where allowing the actuator housing to move
exposes it to vibration or makes precise control difficult. If the actuator is moving delicate equipment or
controlling precision movements, stationary mounting could improve performance and extend the life
of the equipment.
Dual-pivot mounting connects each end of the actuator with a pin or other connector and allows the
actuator to swivel. This gives the actuator freedom to move while remaining attached to the power
source. Clevis mounts and trunnions are common mounts for dual-pivot mounting.
If you need to pivot along more than one axis, a spherical mount is an appropriate choice.
Many factors must be considered when choosing a mounting style, such as speed, type of rotation, the
nature of the equipment being used, the need for stability, and other factors. It is critical to be aware of
the stresses that motion could place on the actuator and other components. The mount should allow
motion in desired directions while preventing unwanted movement and vibration.
The PA-15 is mounted using BRK-15 mounting brackets that are compatible with dual-pivot mounting.

Control of High Speed Linear Actuators

Linear actuators can be “smart” technology. They can be connected to the internet for remote operation
or controlled by a computer system. The actuator could be controlled by a human operator, a remote-
control device, a Wi-Fi signal, or an internal computer.
Automation and autonomous control of devices is a developing field. New advances in machine learning,
neural networks, and other forms of digital technology enable increasingly sophisticated autonomous
control.

The P-15 High Speed Linear Actuator is designed to work with control boxes that easily plug into the
actuator for computer control. Creative Motion Control staff can help to find a control box to suit each
customer’s needs.

Customization of High Speed Linear Actuators

Depending on the application, high speed linear actuators can have additional features. High Speed
Linear actuators like the PA-15 are durable. However, some applications exceed the limits of what most
linear actuators are designed for. High speed linear actuators can be customized to be waterproof,
shielded from radiation, or capable of working in other extreme environments.
● A lock can prevent the actuator from moving in one or both directions.
● A stop block prevents the actuator from moving beyond a certain range.
● Feedback from a motion sensor could allow for adaptive control of the actuator that takes into
account its own motion. For example, an actuator with a motion sensor could use the positional
feedback to stabilize an instrument moved by the wind or an impact. It could also send an error
signal if the actuator is stuck.
High Speed Linear Actuators stocked by Creative Motion Control have anti-rotation capability, are IP65
compliant, and can be customized in many ways. Please consult Creative Motion Control to find out
what options are available. The staff will work with you to create a high speed linear actuator ideal for
your application.

View Post

A Short Introduction To Linear Actuators

An electromechanical linear actuator serves as a standard machine component that converts an electric rotary motor’s rotational movement into a linear force. Linear actuators require a power source input and a control signal input to function. When receiving energy and a control signal input, a linear actuator will create linear force to perform a specified mechanical task.

What Are Variable Speed Linear Actuators?

Variable speed linear actuators utilize the same electromechanical principles as a standard linear actuator to generate a push and/or pull movement. However, with a variable speed linear actuator, users can control the amount of force created to dictate the speed at which the
actuator operates.

A linear actuator consists of the following main components:
● AC or DC motor
● Gearbox
● Spindle or lead screw
● Rod
● Drive nut
The push/pull force generated by a linear actuator allows machines to lift, lower, or otherwiseadjust a target based on an operator’s external signals. Electric actuators remain safe to use and easy to install. Typically, machines utilize actuators to perform repetitive tasks that mayprove too hazardous to execute manually.

As the number of applications for linear actuators continues to grow, the consumer publicbecomes more exposed to their purpose and function. We now see linear actuators in homes,used for various convenient tasks like lifting a pop-up television or standing desk.

Variable speed linear actuators provide operators with an increased level of control over a given subject matter, improving a specified task’s overall safety and producing more reliable, accurate results.

Electric linear actuators cost less, last longer, and require less clearance than most hydraulic and pneumatic actuators. Plus, they represent an environmentally friendly, energy-efficient solution to many everyday tasks.

Types of Variable Speed Linear Actuators

Designs for variable speed linear actuators continue to evolve and improve. They have become more precise, accurate, and efficient over time, leading to the development of high-speed actuators. Let’s go over the main types of variable speed linear actuators.

Rod

Rod actuators represent the most commonly known type of actuator. This type of actuator comes in two main forms: classic and bullet. Let’s discuss both styles of rod actuators in turn.

Classic

Classic or standard rod actuators serve as the most widely seen style of linear actuators. They consist of:
AC or DC motor – The motor converts electricity into rotational motion.
Gears – The gears slow the rotational force, increase torque, and transfer energy to the lead screw.
Lead screw – The lead screw rotates, forcing the rod into inward and outward linear motion.
Rod – The rod’s movement allows the actuator to push, pull, and adjust an object.

With classic rod actuators, the motor remains mounted to the side of the rod. In most cases, it sits parallel to the rest of the actuator. In other cases, such as some ultra high-speed linear actuators, it rests perpendicular to the rest of the device.

Bullet

Inventors developed the bullet rod actuator to fit into tight spaces. Instead of a side-mounted
motor, bullet actuators possess an in-line motor, creating a slimmer, sleeker profile. The thinner
profile allows for new applications that previously seemed too intricate for the extra bulk of a
side-mounted motor. As a result, bullet actuators have a more extended design than classic
ones.

Track

Much like rod actuators, track actuators possess an AC or DC motor, gears, and lead screw. However, in place of a rod, track actuators have a carriage that slides along the length of the rotating lead screw. The length of a track actuator’s stroke remains limited to the length of the lead screw or spindle. The limits on range-of-motion make track actuators simpler to integrate.
One major drawback of track actuators involves the tracks themselves because they sit outside the device. This design exposes the tracks to grease, grime, dust, and other debris, which can gum up the works and impede the carriage from sliding up and down the tracks.

Lifting Columns

Lifting columns also possess a motor, gears, and lead screw but have neither a rod nor carriage. Instead, the lead screw pushes out one of several collapsing, telescopic columns. As their name implies, lifting columns lift objects along a vertical axis. This movement restricts the number of applications available to lifting columns, but it also allows manufacturers to make them more rugged than the other types of linear actuators.

The Benefits of Variable Speed Linear Actuators

A linear actuator with variable speed offers potentially limitless benefits due to the frequent discovery of new applications. However, certain benefits will apply to the use of all variable speed actuators. Let’s go over some of the most common benefits of variable speed linear actuators.

Simple Design

Compared to that of pneumatic and hydraulic options, the simpler design of an electric linear actuator allows for a greater range of applications. An electric linear actuator easily incorporates into existing machinery, requires fewer replacement parts, and demonstrates a high level of reliability.

Easy Installation

In most cases, electric linear actuators represent the easiest mechanical solution. Integration with other machine components proves trouble-free because the electrical energy input and electrical signal input allow a linear actuator to interface well with computer processors and other electrical equipment.

Durability

The simple design of a linear actuator increases the device’s overall durability. A well-made linear actuator will last for years, if not decades, without much maintenance. This longevity makes linear actuators an ideal mechanical solution when incorporated into products used by unsophisticated consumers.

Low Maintenance

The ever-growing popularity of electric linear actuators stems from their reliability, even without receiving regular maintenance. Owners of a linear actuator need only apply lubrication on rare occasions. Other than that, keeping the device free from damage represents the only care users
need to provide.

Low Operating Cost

Compared to hydraulic and pneumatic linear actuators, electric actuators cost very little tooperate. Whereas hydraulic and pneumatic actuators require constant power to maintain position, an electric actuator can hold its place without any energy consumed. Plus, electric actuators remain less likely to break down than hydraulic and pneumatic options.

Compact Size

Electric actuators take up far less space than pneumatic and hydraulic linear actuators. This benefit expands the number of applications for electric linear actuators because their smaller size allows for creative new ways to integrate them into complex machinery. Also, the compact profile of electric actuators leads to a smaller footprint of the machine into which it is integrated.

Quiet

Individuals who have ever used a hydraulic and pneumatic linear actuator know how much noise they can produce. Upon reaching full extension or retraction, non-electrical actuators can create a loud banging sound. On the other hand, electric actuators create far less noise, making them suitable for more sensitive applications.

Environmentally Friendly

Electric actuators rely on relatively clean energy. A rare failure of an electric linear actuator produces no toxins or contaminants. However, the failure of a pneumatic or hydraulic actuator can lead to the expulsion of various forms of pollution into the local environment. For this reason, electric actuators serve as the preferred solution for sensitive projects.

Common Uses for Variable Speed Linear Actuators

It would prove impossible to count all of the current uses for variable speed linear actuators because new applications emerge every day. Human creativity has lent itself to developing thousands of systems with integrated linear actuators, from practical, useful projects to wacky, over-the-top art installations.

Take a look at some of the more common, practical uses for variable speed linear actuators:

● Agricultural equipment
● Food and beverage manufacturing
● Robotics
● Automatic sliding doors
● Sliding windows
● Adjustable solar panels
● Particulate collection containers
● Automatic sliding side steps in vehicles
● Mechanized hatches
● Automatic cutting devices b ● Kitchen appliance lifts
● Automatic valves
● Electronic throttle control
● Computer printers

Who Manufactures Variable Speed Linear Actuators

Variable speed linear actuators play a crucial role in countless machines. The versatility and cost-effectiveness of actuators generate high demand. To meet this demand, many companies manufacture variable speed linear actuators. Some manufacturers focus on making actuators for particular purposes. But, many companies create multipurpose actuators for general use.

Many of the companies that produce high-quality actuators operate out of the United States. For example, Creative Motion Control manufactures innovative linear actuators that possess unique grooved roller bearing and planetary roller screw designs.
