ISO 20051 is an international standard on spherical plain bearings that discusses the criteria for the workability of bearings. ISO 20051 specify a unified method for the calculation of static and dynamic load ratings. Bearing manufacturers don't have unified methods to determine these factors themselves
ISO 20051 gives supplementary background information regarding the derivation of factors
ISO 20051 on spherical plain bearings is relevant to:
Spherical plain bearings are designed to manage high radial loads and provide consistent performance under conditions of marginal lubrication, extreme speed and critical-application stress.
ISO 20051 provides the best guidance to derive the bearing load distribution of radial spherical plain bearings, angular contact thrust spherical plain bearings and angular contact radial spherical plain bearings
As a user of ISO 20051, you can be ensured of static and dynamic load ratings for the design and operation of the spherical plain bearings. ISO 20051 helps you in manufacturing high-quality spherical plain bearings. With the necessary guidance and compliance to ISO 20051, the user can improve the quality and operation of spherical plain bearings.
