Patent ID: 8506170

Claim:
A bearing assembly comprising: an inner ring disposed within an outer ring with rotational elements therebetween adapted for allowing rotational movement of the inner ring relative to the outer ring; the outer ring having an outer diameter surface adapted to be received in a housing for the bearing and an inner diameter surface with a side face extending between the outer diameter and inner diameter surfaces; and an isolator seal disposed in the bearing comprising a stator and a rotor, the stator being releasably mounted to the outer ring and rotationally engaging the bearing inner ring, the rotor being releasably mounted to the bearing inner ring, the rotor having an extension member extending radially outward and rotationally engaging the stator, the extension member having a wiper member extending axially and rotationally engaging the outer ring side face, the rotor and stator being monolithically formed from non-resilient materials, the rotor and stator having adjacent surfaces with at least one cooperating annular groove and annular ridge that enable the stator and rotor to rotate when the isolator seal is installed in the bearing and the bearing is in normal operation.
