Ceramic Bearings For Electric Motors

Since these bearings are constructed from many materials they often operate in hybrid capacities.

Ceramic bearings for electric motors.

Ceramic bearings ceramic bearings are comprised of ceramic rolling elements balls enclosed in a ferrous typically steel inner and outer race. Ceramic hybrid electric motor quality emq bearings have steel races and ceramic balls. Ceramic balls are suitable for applications where high loads high speeds and extreme temperatures are factors. The motor end cap supports the bearing outer race.

Characteristic fluting caused by electric arcing. In most cases motors with ceramic bearings must be special ordered and have long lead times. All motors go down the same assembly line and it is just easier to put the fittings on every. The non conductive silicon nitride ceramic balls in our ball bearings eliminate electrical arcing through the bearing crucial in applications where an electric motor is controlled by a variable frequency drive vfd.

Ceramic bearings offer many advantages over all steel bearings such as higher speed and acceleration capability increased stiffness lower friction and more. The use of nonconductive ceramic bearings prevents the discharge of shaft current. Ceramic bearings are typically constructed with a ferrous inner and outer ring or race with ceramic balls in the place of steel. As with other isolation measures shaft current will seek an alternate path to ground.

Ceramic hybrid bearing styles and sizes. Today we do a quick comparison of two identical cars with the exception of the ceramic bearings and titanium screws. This technology is costly. Any application that requires higher speeds lower friction and longer life are ideal for ceramic hybrid bearings.

Bearings coated with a ceramic insulating material stop electric arcing inset. Ceramic balls are also nonconductive.

Ceramic hybrid bearings are widely used in electric motors aerospace applications performance racing vehicles laboratory equipment under water applications and more.

Ceramic hybrid ball bearings are electrically non conductive. Long life and the need for minimal lubrication make this material appropriate for extreme applications.
