Grooved Roller Bearing

Higher Load Capacity

The CMC Grooved Roller Bearing (GRB) difference lies in the patented grooved roller and race designs. In order to improve durability, the new design increases the number of contact points in the same physical space. More contact points means longer life and greater load capacity to match the performance of CMC’s roller screws.

Extreme Force Density

This force density is unmatched in the industry and enables electric actuation solutions that are otherwise not available due to size constraints. The majority of our roller screw customers include the Grooved Roller Bearing in their assemblies.

Longer Life

Due to the extreme force density, the life of GRBs is five to 10 times the life of the same size angular contact bearing sets. So when you match a GRB to a CMC Roller Screw, you know that you will not have to replace the bearing during the life of the unit.

Grooved Roller Bearing Case Studies

Looking for a thrust bearing with significantly enhanced life expectancy.

CMC’s Groove Roller Bearing technology is very impressive. We get a smaller, lighter bearing that handles more load and lasts significantly longer.

Custom, Super High Capacity Thrust Bearing

CMC not only brought an incredible bearing product to the table, but their excellent engineering support enabled a seamless package for our challenging envelope.

A Roller Screw Providing High Load, High Speed and Long Life

We needed a partner who would analyze our applica-tion and provide a custom roller screw and bearing solution that will give us the life we need at a reasonable cost and lead time. CMC took on the challenge and has done an outstanding job.
