Slew ring bearings are special types of bearings which are generally used in heavy machinery. The difference between these type of bearings and normal bearings is that, they have higher pitch value diameter, the way they are mounted on the structures, working nature which is generally "static", higher load carrying capacity, and larger number of rolling elements.

Polyphenylene sulfide (PPS) is a suitable material for bearings which are used under dry conditions. We performed rolling contact fatigue tests using radial PPS bearings and investigated changes in the material structure and fatigue behavior under dry conditions. From these tests, we found that the bearings stop moving for two reasons melting of wear tracks and build up of adhesion film on
