Ceramic Inner Bearings

Ceramic bearings are used for many applications where standard bearings are unable to operate or in instances where lubrication is an issu.

Ceramic inner bearings.

The use of hybrid ball bearings in today s industries is quickly replacing the more traditional steel ball bearings. Using conventional steel inner and outer rings silicon nitride rolling elements provide excellent electrical insulation while reducing rotating mass and improving heat dissipation. Steel bearings will wear out more quickly due to a number of factors. Since these bearings are constructed from many materials they often operate in hybrid capacities.

For especially problematic applications ntn offers ceramic hybrid bearings. We also build ceramic bearings i e bearings with ceramic races but they are not as common because they are less durable. Ceramic bearings are comprised of ceramic rolling elements balls enclosed in a ferrous typically steel inner and outer race.
