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.

Abstract: A sealing arrangement for sealing a shaft passing through a bore in a wall is disclosed. The sealing arrangement comprises a radial shaft sealing ring which surrounds the shaft with radial pre-tension, forming a seal on the circumference of the shaft via at least one sealing lip made of an elastomeric material. The sealing lip is affixed on a first shank of an essentially L-shaped first reinforcement ring which faces radially inward. A second shank extends in an axial direction, is mantled by elastomeric material at least in the portion which extends axially, and touches the wall with radial pre-tension, forming a seal. In the radial direction, between the shaft and the second shank, is arranged a rolling bearing, which contacts the shaft via its inner ring and contacts the mantled partial region of the second shank via its outside ring.

Abstract: A guide bushing having an integrated seal for the clutch-release bearing of a gear unit, comprising a connecting sleeve [pipe socket] circumferentially surrounding an input shaft of the gear unit with radial clearance and a mounting flange affixed to the connecting sleeve, whereby, on the side facing the outer wall of the gear unit, the connecting sleeve has an essentially Z-shaped cross-section, whereby the Z-shaped cross-section is comprised of a first axial side piece situated radially to the inside and of a second axial side piece situated radially to the outside, and whereby the first and the second axial side piece are joined by a radial side piece.

Abstract: A cassette shaft seal in which the outer ring (3) and the inner ring (11) have an opposite angular profile and together enclose an annular space (5) of substantially rectangular cross section. This annular space is bounded by an outwardly projecting flange (8) of the inner ring (11), which revolves together with the shaft that is to be sealed. The gap remaining between the flange (8) and the outside ring (3) is expanded in cross section by segmental cutouts uniformly distributed around the circumference, through which, under normal operating conditions, the volume of liquid contained in the annular space (5) is constantly renewed.
