Bearing Stresses | Engineering Library
11.1 Introduction to Bearing Stresses. The stresses developed when two elastic bodies are forced together are termed bearing stresses. They are localized on the surface of the material and may be very high due to the small areas in contact. The design information given in this section assumes either static loading or low velocity loading.

A guide to plain bearing materials in linear motion applications
If the shaft is not suited for the bearing material, it will increase wear and shorten the bearing's service life. It is critical to have the right match so that together they extend the life of the assembly. For example, with a PTFE composite bearing, the ideal surface finish is 0.2 to 0.4 µm (8-16 Ra). If the surface finish is rougher ...
