Ceramic Bearings For Electric Motors

Ceramic hybrid bearing styles and sizes.

Ceramic bearings for electric motors.

In most cases motors with ceramic bearings must be special ordered and have long lead times. These bearing operations enable fresh grease to reach the bearing and push out excess grease. Long life and the need for minimal lubrication make this material appropriate for extreme applications. Bearing and motor manufacturers have given various reasons as to why grease fittings are installed on bearings and motors that have sealed bearings such as.

Ceramic balls are suitable for applications where high loads high speeds and extreme temperatures are factors. Characteristic fluting caused by electric arcing. The motor end cap supports the bearing outer race. All motors go down the same assembly line and it is just easier to put the fittings on every.

Ceramic hybrid electric motor quality emq bearings have steel races and ceramic balls. Ceramic hybrid bearings are widely used in electric motors aerospace applications performance racing vehicles laboratory equipment under water applications and more. The use of nonconductive ceramic bearings prevents the discharge of shaft current. Since these bearings are constructed from many materials they often operate in hybrid capacities.

Ceramic bearings ceramic bearings are comprised of ceramic rolling elements balls enclosed in a ferrous typically steel inner and outer race. Any application that requires higher speeds lower friction and longer life are ideal for ceramic hybrid bearings. As with other isolation measures shaft current will seek an alternate path to ground.

Ceramic hybrid ball bearings last longer. Bearings coated with a ceramic insulating material stop electric arcing inset. This technology is costly. Ceramic bearings offer many advantages over all steel bearings such as higher speed and acceleration capability increased stiffness lower friction and more.

Ceramic bearings are typically constructed with a ferrous inner and outer ring or race with ceramic balls in the place of steel. Ceramic hybrid ball bearings are electrically non conductive.
