Scope

This document specifies the basic function values used in the calculation of fluid hydrodynamic radial sliding bearings and cylindrical bearings under fully lubricated conditions.
The assumptions and boundary conditions corresponding to these values are given in GB/T 21466.1. The parameter values required for the calculation can be obtained from the bearing characteristic tables, diagrams, and formulas.
The description of the symbols used and calculation examples can be found in GB/T 21466.1.
