Abstract 1,272,925. Sealing rolling bearings. TRW Inc. 12 May, 1970 [26 May, 1969], No. 22948/70. Headings F2A and F2B. A rolling bearing assembly is provided with a combination lip and labyrinth seal. An elastomeric member 30 has a bead 38 which is located in a circumferential groove 20 in the outer race 10. The member 30 has a lip 48 provided on an axially inwardly extending flange 44 which sealingly engages the inner race 13. The member 30 also has an axially outwardly opening channel. A rigid annular member 31 of the same shape as the elastomer 30, is secured to the axially outer side of the elastomeric member terminating short of the radial ends of the member 30. A rigid annulus 12 is secured to the inner race by an inwardly extending portion 51, and a radially outer portion 52 extends into the channel in the member 31, thereby defining a labyrinth seal, and acting as a flinger. In a modification (Fig. 4, not shown), the flinger (60) is fixed to the race by tabs (61) which are a force fit on the race, and the flinger may have a portion which is located in a groove (62) in the race.
