Rolling bearings - Linear motion rolling bearings - Part 2: Static load ratings1 ScopeThis document specifies the calculation methods for the basic static load rating, static equivalent load and static load safety factor of linear motion rolling bearings. This document applies to linear motion rolling bearings manufactured from contemporary, commonly used, high-quality, hardened bearing steel according to good manufacturing methods and basically of conventional design regarding to the shape of the rolling contact surfaces. This document does not apply to designs in which rolling elements run directly on the smooth surface of mechanical equipment, unless the surface is equivalent in all respects to the raceway of the linear motion rolling bearing component it replaces.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
