An axial shaft seal disposed between a housing wall and a rotating shaft includes an outer ring insertable into the housing wall in a stationary and sealing manner and an inner ring connectable to the shaft in a non-twisting and sealing manner. The outer ring includes a sleeve having a polymer material extending radially inward and having a spring bellows form. A radially inward end portion of the sleeve has a first sealing surface. The inner ring includes a ring flange extending radially outward so as to provide a second sealing surface for axially mating the first sealing face.

Axial shaft seal

A sealing ring having a sealing disk made of polymer material, which has a retaining segment and a sealing segment. The retaining segment is connected to a support ring and the sealing segment is curved in the direction of a space that is to be sealed off and sealingly surrounds a shaft against which it forms a seal on its peripheral side under radial prestressing. The sealing segment on the side facing the shaft has a first surface profiling, the first surface profiling on the side facing the space to be sealed off being formed by at least one recirculating element, and at least one dust lip being arranged on the side of the recirculating element facing away from the space to be sealed off. Between the recirculating element and the dust lip, an annular, self-contained sealing bead is arranged which sealingly surrounds the shaft on the peripheral side.

Sealing ring having a sealing bead

A sealing sleeve made of a polymer material especially for small-dimension installation spaces, the sealing sleeve having a retaining segment and a sealing segment, the retaining segment being connected to a supporting body and the sealing segment on the peripheral side encircling a shaft to be sealed or a barrel ring in a sealing manner under radial biasing and having on the side facing the shaft a surface profiling for recirculating the lubricant, wherein the connecting diameter (interior diameter (D) of the enclosing part ( )) is 1.0 to 1.05 times the shaft diameter (W) plus four times the sleeve thickness (d).

Sealing sleeve, especially for small-dimension installation spaces

A sealing ring, including a support ring made of an impact-resistant material, and a lip ring made of PTFE, where the lip ring has a holding segment and a sealing segment, and where the holding segment is connected with the support ring by an intermediate layer made of a polymer material. The holding segment and the sealing segment are made of two different PTFE compounds, each adapted to their purpose of use.

Sealing ring

A lipped sealing ring for a mechanical component that moves relatively to it. The lip is of a polymeric material, is flexible, and is forced subject to resilient compression against the component in the vicinity of a sealing gap. A helical shoulder extends longitudinally and at an acute angle to the axis of the component through at least one point along the circumference of the gap. The sealing gap is packed with wax at least in the vicinity of the helical shoulder.
