A cage particularly for a tapered roller bearing comprises a large end ring 2 and a small end ring 1 both of plastics material joined by integral connecting bars 3, also of plastics material, which define pockets for receiving the bearing rollers. The bars are shaped to define a groove 6 which extends axially along the inner face. The various grooves 6 are commoned in an annular trough 4 into which lubricant may be supplied. During use, lubricant passes from the trough 4 along the grooves 6 from right to left by centrifugal force, thus leading to an improved distribution of lubricant within the bearing. In practice the assembly will require reinforcement if it is to withstand the high centrifugal forces encountered during use. One way of achieving such reinforcement is to make the assembly a snap fit within a conventional metal cage. <IMAGE> |
