Overview
This document specifies methods of calculating the basic dynamic load rating and basic rating life for linear motion rolling bearings manufactured from contemporary, commonly used, high quality, hardened bearing steel in accordance with good manufacturing practice and basically of conventional design as regards the shape of the rolling contact surfaces. The life of linear motion rolling bearings is defined and the conditions are established for reliable life calculations. This document is not applicable to designs where the rolling elements operate directly on the slide surface of the machine equipment, unless that surface is equivalent in all respects to the raceway of the linear motion rolling bearing component it replaces. This document has been prepared by Working Committee NA 118-01-08 AA "Tragzahlen und Lebensdauer" ("Load ratings and life") at DIN Standards Committee Rolling Bearings and Plain Bearings (NAWGL).
