Abstract

PURPOSE: To elongate the fatigue life of a bearing by lightening the edge load, by means of setting up circumferent grooves at the facing rolled surfaces to the circumferent part of the roller.
CONSTITUTION: An outer wheel has a fixed guard at both side of a track surface 11, and a roller 3 is not crowned. Circumferent grooves 22 are formed on the facing surface to circumferent part 31 of th roller 3 at an inner wheel 2. The side fringe of the circumferent grooves 22 are formed by means of continuing to the track surface 21 smoothly.
