Abstract

A sealed rolling bearing in which the seal consists of a sealing lip and a sealing projection connected to a sealing body. When the sealing body is seated in a groove formed in the outer ring, the sealing lip abuts a side surface of a groove formed in the inner ring with prestress. The sealing lip and sealing projection abut under the influence of the prestress to form a conical, outwardly directed centrifugal surface for ejecting moisture and dirt through a gap seal formed between the sealing projection and a shoulder of the bearing inner ring.
