A ceramic bearing can weigh significantly less than steel bearings, and because of the lower weight, centrifugal loading and skidding are reduced, meaning that ceramic bearings can operate faster than steel bearings. The lower weight of the ceramic bearing means friction and rolling resistance are reduced. Because the ceramic bearing is lighter in weight, it can spin faster and also uses less energy to maintain speed. W.M. Berg uses high quality ceramic coated aluminum housing for this precision manufacturing part, manufactured to satisfy your needs. W.M. Berg carries ceramic bearings in many sizes, diameters and lengths, as well as open and closed styles to adequately support all your ceramic bearing needs. W.M. Berg will customize ceramic bearings to meet your specific needs with our expert technicians and engineers.
