Abstract
In a roller bearing comprising an outer ring which has an inwardly bent annular flange, a sealing ring is loosely interposed the inner circumference of the flange and a shaft with a suitable clearance. An element(s) for imparting a forced rotation to the sealing ring is, also, provided on either one or both of the sealing ring, cage, or the flange of the outer ring to drive the sealing ring by the rotation of the roller, cage or the flange of the outer ring. By virtue of this construction lubricant can be forcibly circulated through the sealing ring between and throughout the interior and exterior of the roller bearing.
