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.


Wettability; Bearings


No such standard currently exists for this topic. The rationale is outlined in the scope.

The title and scope are in draft form and are under development within this ASTM Committee.
