Bearing seal

摘要

A two-piece seal is provided for a bearing assembly. The seal includes a first seal ring or labyrinth element received on an inner diameter of the bearing outer race and a second seal ring or labyrinth received on an outer diameter of the bearing inner race. The labyrinth include ribs and channels 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 is formed on one of the labyrinth elements to form a dynamic seal between the two labyrinth elements at an inner end of the labyrinth path.
