ASTM WK82882
New Practice for Surface Wettability of Bearings
1. Scope
1.1 This standard covers two practical methods of evaluating the wettability of rolling element bearing components and/or relevant ring surfaces by visual inspection following exposure to a liquid. 1.1.1Finishing & manufacturing steps are unique to the bearing ring/rolling element; verification is carried out on the actual relevant bearing ring surfaces (primarily raceways) and rolling elements, rather than testing efficacy of the cleaning process by performing a wettability test on a coupon or other test item. 1.1.2 Wettability testing is meant to evaluate bearing surfaces for the likelihood to form and maintain a continuous film of lubricant.Keywords
