1,217,086. Bearings. NADELLA, and A. PITNER. 15 Jan., 1968 [19 Jan., 1967], No. 2108/68. Heading F2A. A roller bearing has a cup 1 with an end-wall 1a, a cylindrical race portion 1b and rollers 2; is provided with a cage 3 and a seal 6; and has an eccentric mass of grease 7 therein which partly covers both the end-wall 1a and the cylindrical race portion 1b. When a shaft A is located in the bearing and is rotated, the movement of the rollers, together with centrifugal force, spreads the grease throughout the annular zone between the portion 1b and the shaft A. |
