Title:Plain Spherical Bearing Radial and Axial Clearance Measurement
Issuing Committee:Acbg Plain Bearing Committee
Scope:This test method provides a guidance for determiningn the total free play between the ball and outer ring of a spherical bearing when measured in both the radial and axial directions. Bearings covered by this test method include all plain spherical type bearings, both self-lubricated (lined) and metal-to-metal.
