Abstract

A roller bearing assembly includes at least one roller bearing having an outer ring, an inner ring, and roller bodies disposed therebetween, as well as a radial shaft seal ring having a support ring and a seal lip. At least one end side of the outer ring includes a receptacle for retaining the support ring. The support ring extends axially in an outwardly projecting manner beyond the end side of the outer ring and up to an outer circumferential surface of the inner ring. The seal lip connected with the support ring sealingly abuts on the outer circumferential surface of the inner ring at a position that is axially internal of the end side of the outer ring.
