Abstract
A bearing has an outer ring, an inner ring and rollers between the rings. The inner ring has axial outward extensions with stepped radially outward surfaces receiving the radially outward extending end washers. Inward extending grooves are formed in the axial surfaces of the steps. Inner axially extending surfaces of the end washers have complementary grooves about twice as deep as the grooves in the inner ring ends. To assemble the washer on the inner ring, a C-shaped external retaining ring is expanded into the washer groove, while the washer is slipped over the axially extending surface of the step on the outer end of the internal ring. The external retaining ring slides along the lateral surface of the step until it reaches the groove and springs inward into the groove. Half of the thickness of the external retaining ring fits in the groove. The outer half of the thickness remains in the groove in the inner wall of the washer, firmly locking the washer on the stepped outer end of the inner ring. A tapered end washer installation plug is inserted in an end of the inner ring so that the maximum dimension of the tapered end is adjacent the end of the axially extending surface in t…
