Abstract

A seal for a rolling bearing having an inner bearing ring, an outer bearing ring, and rolling elements rolling in races therebetween, wherein a cover is affixed to the outer bearing ring and carries a sealing lip engaging the side surface of a groove adjacent an end of the inner bearing ring. A shoulder at the end of the inner bearing ring defines a gap seal with the cover. The cover extends substantially normal to the axis of the bearing and the sealing lip is either slightly conically inclined, or defines an annular outwardly extending groove.
