A conical bearing cage (10) for a tapered bearing assembly (12) comprising an integral plastic member having a central axis. The member includes a large circular ring (14) and a small circular ring (24) interconnected by a plurality of circumferentially spaced bridges (34). The bridges (34) have top surfaces (36) and sides extending downwardly therefrom with tapered portions (40) immediately beneath the top surfaces (36) thereof to define sharp lips (42). A rib (44) is disposed on the top surface (36) of each bridge (34) and extends between the rings (14, 24). The sides (46) of each rib (44) are spaced from the adjacent lips (42) and are also parallel to the central axis of the cage (10). Further, the small ring (24) is smaller in diameter than the large ring (14) thereby providing a one-piece plastic cage member (10) of sufficient strength and operating characteristics, yet capable of being molded in a two-part mold. |
