With patented variable contact raceway geometry, the SKF clutch release bearings are the first truly clutch-compatible bearings on the market. The variable contact design permits maximum speeds at maximum loads, resists wear for longer life, and minimizes noise and vibration. 

What's more, a self aligning design allows these bearings to control clutch conditions associated with the misalignment of drivetrain components. They also feature a unique sealing system that keeps contaminants out and grease in.
