MR18307-2RS-HC-LC Steel Bearing
LOW CONTACT SEALS TO REDUCE FRICTION
Hybrid ceramic bearings are the most common type of ceramic bearing, constructed of steel inner and outer races with ceramic Si3N4 balls in place of steel ones.
Hybrid ceramic bearings have various advantages over all steel bearings, such as higher speed and acceleration capability, increased stiffness, higher accuracy, lower friction and low heat generation, low thermal expansion.
