Abstract
Seal rings are molded from an injection moldable elastomeric material, with the rings being designed to have an axially thick body, a rib at the outer periphery for mounting engagement within the outer race ring groove, and a flexible sealing lip at the inner periphery for engagement with the inner race ring. To provide a rigid support body for the ring, particles are dispersed within the moldable material to be injected into the molds, the filler particles having a minimum dimension substantially larger than the maximum dimension of the sealing lip so that, during molding, the filler particles are excluded from the lip but are embedded in the body portion to make that portion more rigid.
