Surface Profile Observation of PTFE Thrust Bearings under Rolling Contact Fatigue in Water
The life of the PTFE thrust bearing under rolling contact fatigue (RCF) was investigated.The different conditions of axial loads and the rotating speeds under water were applied.The shapes of the bearing race before and after the tests were measured by a two-dimensional shape measurement sensor.The wear loss of PTFE bearing was rarely generated and the shape of the bearing changed slightly in the test.However,it was found that the lifetime of PTFE bearing depended on the temperature generated in the contact surface.In our testing machine condition,the bearing was collapsed over a load of 1600 N.
