ABSTRACT:
A dustcap (10) for a bearing assembly (12) includes a sidewall (50) having a first end (52) and a second end (54). An endwall (56) extends from the second end (54) of the sidewall (50) to form a cup. A lip (60) extends radially outward from the first end (52) of the sidewall (50). The lip (60) has a first angled portion (62) and a second angled portion (64) connected to form a circumferential apex (66). The bearing assembly (12) has an outer race ring (20) that cooperates with an inner race ring (22) to form a raceway (26) in which a plurality of balls (24) are disposed. The outer race ring (20) has a seal groove (40A) disposed therein which is configured to accept the apex (64) of the lip (60) of the dustcap (10) in a snap fit. By connecting the dustcap (10) to the outer race ring (20) of the bearing assembly (12), the dustcap (10) remains aligned with the bearing assembly (12) when the bearing assembly (12) becomes misaligned. By remaining aligned with the bearing assembly (12), the dustcap (10) is not ejected from the bearing assembly (12).
