A wheel bearing includes tapered rollers (72) as well as raceways (60, 76, 82). The rollers of the inboard row roll along tapered raceways on a cup pressed into the bearing cavity and a cone (66) pressed over the spindle (40). The bearing is closed by an inboard seal (12, 174, 184, 208) which includes a case (130) pressed into a bore (24), a shield (132) pressed over a thrust rib at the end of the cone, and a seal element (134, 178) bonded to the case and establishing a fluid barrier with the shield. The shield has a wall (142, 188) which serves as a tone ring, and this ring is monitored by a sensor (14, 186, 212). A CV joint (8) engages the spindle, and it carries a slinger (16) and further has a seal element (154) which establishes a fluid barrier around the end of the cavity. |
