  • Patent number: 10029356
    Abstract: A mounting device for a sealing ring, having a transport/mounting protective sleeve for the sealing ring and a sleeve-shaped punch with which the transport/mounting protective sleeve is movable on both sides in axial direction and automatically removable, wherein the protective sleeve has an inner step, extending axially, and an outside diameter corresponding to the outside diameter of a machine element to be sealed, and an axial length substantially corresponding to the axial length of the sealing ring, wherein the inner step is bounded axially counter to mounting direction by at least one end-side stop for the sealing ring, which stop forms part of an outer step likewise extending in the axial direction, wherein the outer step has a first driver surface with which at least one latching-lug-shaped driver of the punch can be engaged for automatic removal of the protective sleeve when the punch moves counter to the mounting direction.

  • Patent number: 9033345
    Abstract: A radial shaft seal for separating two media includes two radial shaft sealing rings each including an axial surface and a sealing lip. The sealing rings are disposed with the axial surfaces facing one another and the sealing lips axially opposed to one another with a space between the sealing lips including a vent. At least one of the sealing rings includes clamping cams configured to grip an inner rim of the other sealing ring so as to join the sealing rings in a form-locking, rear-engaging position relative to each other.

  • Patent number: 6474653
    Abstract: A seal arrangement for a shaft having a broad rpm range, supported in a housing, in particular for axle drives. A radial shaft seal, arranged in the housing bore hole, seals the shaft bearing space from loss of lubricant. A baffle plate, joined to the shaft, and having a lip seal, is aligned radially to the inside, which under the effect of centrifugal force lifts off from its sealing surface at higher rotational speeds of the shaft.
