Abstract
A rolling contact bearing, wherein the surface of the raceways of an outer member and/or an inner member are randomly formed with an innumerable number of microconcavelike pits, the surfaces are provided with said pits having a surface roughness value smaller than 0.25 microns and a skewness Rsk value such that −3.5<Rsk<−1.0.
Claims3
A rolling contact bearing, comprising
- an outer member;
- an inner member;
- and
- at least one raceway on the outer member or the inner member, wherein a surface of the at least one raceway is a microroughened surface having a skewness (Rsk) value such that −3.5<Rsk<−1.5 and a surface roughness value (Ra) less than 0.1 microns.
