Hybrid ceramic bearings

Hybrid ceramic bearings consist of ceramic balls (or rollers) and steel races, cages/retainers and seals/shields.

The balls/rollers may be made of the following ceramics:

The steel parts are made of Chrome steel (eg. AISI 52100) or Stainless steel AISI 316.

Hybrid ceramic bearings are mainly used in high speed and insulating applications.

Full ceramic bearings

Full ceramic bearings are made only of ceramics (contain no steel parts).

The following ceramics are used for manufacturing full ceramic bearings:

Full ceramic bearings are widely used in harsh environments (chemicals, vacuum, high temperature, radiation).
