Bearing Materials - Ceramics, Chrome Steels, Stainless Steels, and Plastics | AST Bearings - Ball Bearings - Precision Miniature 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.

Bushing or Bearing, what’s the difference?

15/1/2021· There are broadly two ball bearing types: deep groove ball bearings which have a high radial load capacity, and angular contact ball bearings which can manage both high radial and axial loads. Ball bearings are used in a great range of appliions, from complex aerospace engineering to the everyday skateboard.
