Advantages of CMC Grooved Roller Bearings

Higher Load Capacity

Born from CMC’s roller screw design, the CMC Grooved Roller Bearing (GRB) difference lies in the patented grooved roller and race designs. In order to improve load capacity, speed ratings, and durability, this unique design increases the number of contact points in the same physical space. More contact points mean longer life and greater load capacity to match the performance of CMC’s roller screws. Hence almost all of CMC’s roller screw customers include integrated GRBs in their assemblies.

Extreme Force Density

The force density of CMC’s GRBs is unmatched in the industry and enables electric actuation solutions that are otherwise not available due to size constraints. CMC’s bearings are on average 35%-50% smaller than a comparable set of angular contact bearings.

Longer Life

Due to the extreme force density, the life of GRBs is 5-10 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.
