ABSTRACT:
A trolley wheel assembly (10) securely sealed to prevent loss of lubricant therefrom and entrance of contaminants therein. The assembly (10) comprises an inner race (12) disposed about an axis of rotation (14) and an outer race (16) concentrically disposed in a spaced relationship about the inner race (12). A plurality of ball bearings (18) are disposed between the inner race (12) and the outer race (16). An outer sealing ring (20) extends radially inwardly from the outer race (16) toward the inner race (12). An inner sealing ring (22) is rotatably disposed about the inner race (12), extending radially outwardly and contiguous the outer sealing ring (20). A wave washer (24) disposed about the inner race (12) biases the inner sealing ring (22) into constant friction engagement with the outer sealing ring (20). A plurality of backup inner sealing rings (26,27) provide a secondary seal about the inner race (12).
