1459749 Bearings A PITNER and NADELLA 20 Dec 1973 [22 Dec 1972] 59280/73 Addition to 1211578 Heading F2A A radial rolling bearing comprises a ring 3 whose inner cylindrical surface constitutes a raceway for caged rolling elements 1 which are capable of axially bearing at one end against a radial surface 4 of the ring and at the other end against a member 5 defining an abutment surface and axially movably retained inside the bearing by means 6 connected to or formed on the corresponding end of the ring, the member 5 projecting radially inwardly beyond the means 6 so that axial thrust can be transmitted via the elements 1 to the surface 4. In a further embodiment (Fig. 2, not shown), an elastomeric ring is located between the member 5 and a shoulder B on the inner bearing member. The means 6 may carry a ring in sealing contact with the outer cylindrical surface of the shoulder B. |
