Application Summary AI generated

This standard specifies methods for calculating the static load ratings of linear motion rolling bearings, defining the maximum static load a bearing can withstand without permanent deformation. It is applied in the design, selection, and quality verification of linear guide systems and ball screws used in machine tools, industrial robots, and automated production equipment. Engineers and procurement professionals use it to ensure bearing reliability under stationary or slow-oscillating load conditions.
