Ceramic balls are over 100% harder than steel balls. In a hybrid bearing, the extremely hard and smooth Ceramic Ball keeps raceways clear of contaminants by pushing them away from the contact patch. In addition, the ceramic ball remains extremely smooth, preventing ball to race damage. For the end user, this means reduced bearing wear and longer bearing life at high precision.

Benefits of Hybrid Bearing Attributes: Dissimilar Materials (Steel and silicon nitride) Less Wear Lower Operating Temperature Higher Speed Extended Bearing Life Lower Friction Stiffness Lower Vibration
