Abstract
An improved type of rolling element bearing, in which race land regions are protected against wear or scoring, is described. In particular, it is shown that a coating of a hard, wear-resistant material such as titanium nitride, applied to the race land region of a rolling element bearing, is effective in preventing wear or scoring of the race land region.
