Abstract
A radial needle bearing includes an outer ring having a race track formed on the inner surface thereof and inward flanges at both ends thereof, a retainer with a plural number of pockets, rotatably located within the outer ring, a seal ring located between the end face of the retainer and inside the inward flange, the seal ring functioning to impede the flow of a lubricating oil flowing in the axial direction within the outer ring, and a plural number of needles rotatably held within each of the pockets. The radial needle bearing is improved in that the outer diameter of the retainer is slightly smaller than the diameter of the race track, and the inner diameter of the retainer is slightly larger than the inscribed circle of the plural number of needles.
