Cageless roller bearing

摘要

In a cageless (full-type) bearing consisting of at least one race, rolling elements and two retaining discs which are situated on the race and prevent the rolling elements from falling out, the rolling elements having axial projections which project into an all-round groove in the retaining ring, the end faces of the rolling elements have blind holes into which axially projecting plastic sleeves or plastic bushes are press-fitted. This provides a cageless bearing in which it is possible to use rollers that are cheap to manufacture.
