<p>A two-piece seal (30) is provided for a bearing assembly (10). The seal (30) includes a first seal ring or labyrinth element (34) received on an inner diameter of the bearing outer race (12) and a second seal ring or labyrinth (32) received on an outer diameter of the bearing inner race (14). The labyrinth (32, 34) include ribs (78, 51) and channels (80, 50) on facing or opposed surfaces which are sized and shaped such that the rib of one seal ring is received in the groove of the opposing seal ring to thereby form a labyrinth path between the two labyrinth elements. Additionally, a flexible seal lip (82) is formed on one of the labyrinth elements (32, 34) to form a dynamic seal between the two labyrinth elements at an inner end of the labyrinth path (88).</p> |
