ABSTRACT:
A sealing arrangement for two machine elements concentrically arranged with respect to one another for relative rotation, especially for the inner and outer bearing rings of a rolling bearing, consists of a holding ring circumferentially arranged spring fingers radially snappable in an annular groove in the outer or inner ring, and a sealing seal of an elastically compressible plastic connected thereto, the holding ring being adapted to be axially inserted between the inner and outer bearing rings. In order to maintain a precise centering of the seal connected to the holding ring, between the outer and inner ring, the holding ring has spring fingers on its axially outer end and a centering section on its axially inner end. The centering section is radially supported in the bore of the outer ring or on the outer surface of the inner ring. The seal has a mounting section which is axially clamped between the centering section and a radially extending inner shoulder of the outer or inner ring, adjacent the bore of the outer ring or the outer surface of the inner ring.
