Purpose:

This test method outlines a standard procedure for performing unidirectional load dynamic testing of self-lubricating bearings at room temperature, elevated temperature or sub-zero temperature, dry or contaminated with fluids. The wear data from these tests is to be used for qualification and to establish bearing design criteria.

Classification:

Bearings covered by this test method shall be plain spherical bearings, which are self-aligning or plain sleeve bearings.
