Influence of raceway surface finish on white etching crack generation in WEC critical oil under rolling-sliding conditions

In this work, cylindrical roller thrust bearings (CRTBs) with different raceway surface finishes were life tested under rolling-sliding conditions in WEC critical oil. After testing, white etching cracks (WECs) had formed in the raceways of the commercially available standard CRTBs from the test rig manufacturer. However, after embedded abrasive particles were introduced into the raceways (from the lapping process), neither the post-test...
