Abstract 1,044,719. Bearings. TORRINGTON CO. Dec. 10, 1964 [Dec. 10, 1963], No. 50229/64. Heading F2A. In a roller bearing assembly, a shaft 14, Fig. 1 (not shown), serves as an inner race; an outer race 15 is mounted in a housing 10 and carries a shaft-riding seal 23, Fig. 2 (not shown), thereon; and rollers 16, having reduced portions 17 at each end thereof are positioned between the races. The outer race 15 is shaped at one end 18 so as to form a seal-carrying portion 22 and is shaped at both ends 18, 19, so as to form rollers-retaining lips 20, 21 which engage the portions 17 of the rollers. The seal 23 is secured to the outer race 15 by direct moulding, or by an adhesive, and has a shaft-engaging lip 24 which is deflected to the left or to the right according to the positioning of the shaft 14 in the bearing. . In a modification, a cage 28, Fig. 4 (not shown), is provided and the reduced portions 17 of the rollers are omitted.
