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.

Bearings consist of rolling elements (balls, cylinders or barrel shapes) and rings which form the raceways. The manufacturing process for the rolling elements involves the high reductionrate plastic deformation of raw, cast material, into billets with square sections. The deformation helps to break up the cast structure and to close porosity.
Rolling ball tack is defined as the distance a rollin g ball travels on an adhesive layer before stopping, after it was allowed to roll down a defined incline. An adhesive sample is coated 25g/m² onto 50µ polyester film, covered with a release paper and allowed to condition for 24 hours. A clean steel ball 10mm in diameter is released and ...
