Hybrid ceramic bearings have traditional 52100 steel or Stainless Steel rings with ceramic silicon nitride (Si3N4) balls. In addition to being excellent electric insulators, hybrid bearings have a higher speed capability 1.2-1.5 time limit of rotations compared to steel bearing and will provide longer service life, lower friction and a lower level of energy consumption than all-steel bearings in most applications. Ceramic hybrid bearings are widely used in electric motors, aerospace applications, performance racing, high temperature equipment, under water applications and more.
