Oppositely extending rim portions project from the lip portion in concentric fashion with respect to the lip portion to define respective spaces for accommodating grease layers. The grease layers and the lip portion constitute a seal against the inner race thereby preventing dust or other foreign particles from passing through the grease layers and the lip portion.
