Rolling bearings are common in mechanical systems and are used to reduce friction between rotating components. The performance and lifetime of the bearings is closely linked to the surface texture of their raceways. This guide outlines good practice for surface roughness measurement of bearings, building upon the recommendations of previous Good Practice Guides. Common roughness parameters used when studying bearings are discussed, and differences in terminology clarified.
