5. Inspection of Bearings | Maintenance | Services | NSK Global

Separable bearings such as tapered roller bearings may be checked by individually examining their rolling elements and the outer ring raceway. Large bearings cannot be rotated manually; however, the rolling elements, raceway surfaces, cages, and contact surface of the ribs should be carefully examined visually.

Bearing Materials - Ceramics, Chrome Steels, Stainless Steels, and Plastics | AST Bearings

Bearings made with ceramic materials fall into a specialty niche in the bearing industry. The most common arrangement is a hybrid bearing, usually with stainless steel rings and ceramic balls. The most common ceramic material used is silicon nitride. Balls made from this material are hard, up to Rc78, and have a very smooth surface.
