  • Patent number: 6715768
    Abstract: 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.

  • Patent number: 6520507
    Abstract: 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 (31)) is 1.0 to 1.05 times the shaft diameter (W) plus four times the sleeve thickness (d).
