Application Summary AI generated

This standard specifies the technical requirements, dimensions, and test methods for bimetallic bushings with a plastic overlay used in plain bearings. It is applied in the manufacturing and quality control of sliding bearings for mechanical systems, such as automotive engines, industrial machinery, and agricultural equipment, where reduced friction and wear resistance are critical. The standard ensures consistent performance and interchangeability of these bushings in high-load, low-speed applications.
