ABSTRACT:
A needle roller bearing is directed to avoid a possibility that an inner peripheral surface of a bore in a housing may be ground or scraped by an edge defining a peripheral lip region of an opening in an outer race when a needle roller bearing is to be press-fitted into the bore in the housing and also to eliminate the need to adjust the position of a roller retainer while increasing a physical strength of the roller retainer. For this purpose, the outer race is formed with a first opening having a pair of axially spaced tabs bent so as to incline radially inwardly of the outer race from the remaining portion of the outer race. The roller retainer is in the form of a tubular member having a circumferentially continuous wall formed with a second opening at a location aligned with the first opening in the outer race. The roller retainer has a substantially intermediate portion protruding radially outwardly so as to have an outer diameter greater than that of any one of the opposite ends of the roller retainer.
