ABSTRACT:
The roller bearing seal includes a ring-shaped member integrally connected to an outer race of the roller bearing. The ring-shaped member has an outer lip portion that is spaced a predetermined amount from the inner race of the roller bearing so as to provide a gap between the ring shaped seal member and the inner race. 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.
