ABSTRACT:
A seal for sealing a shaft passing through a housing wall is presented. The seal comprises a radial shaft-sealing ring with at least one sealing lip of elastomeric material under radial pretension. The sealing lip is fastened to a first leg of an essentially L-shaped first reinforcing ring. The second leg of this reinforcing ring extends axially and covers and abuts the outer ring of a roller bearing at least partially. The second leg is jacketed on the side facing the housing wall with an elastomeric material. The jacket is surrounded on the side facing the housing wall in a partial axial area by a second reinforcing ring of a resilient material. The ring abuts the housing wall at least partially during proper use under radial pretensioning. The jacket projects beyond the second reinforcing ring outside the partial axial area in the radial direction as manufactured.
