These bearings are in a class by themselvers. If you want the best there is, that is it. the Cerbec ceramic balls are much lighter, harder, stronger, waterproof and longer-lasting than the finest steel balls.

They accelerate and roll faster and farther and resist dirt and moisture better. The ceramic helps repair damage to the races that can be caused by dirt.

Single removable non-contact rubber shield allows easy cleaning and no added friction.
