  • Patent number: 10995793
    Abstract: A boot needle roller bearing is designed to reduce friction between a flexible boot non-rotatably attached to a differential housing and a rotatable half-shaft. A plurality of rollers is retained axially between a first lip formed in the outer ring and a set of protrusions that are formed after installation of the rollers by bending prongs inwardly. The inner ring is retained axially between the protrusions and a second lip formed into the outer ring after installation of the inner ring.

  • Patent number: 9827852
    Abstract: A shaft bearing assembly including a housing, in which a bearing is arranged, is disclosed. The housing includes a first and second flange part. The first and second flange parts can be connected to each other, wherein the two flange parts jointly form a receptacle for the rolling-element bearing, wherein one of the flange parts has at least one securing interface and the other has at least one securing counter-interface, wherein the first and second flange parts can be connected to each other and/or fixed to each other in a positive-locking manner by the securing interface and the securing counter-interface that prevents the two flange parts from detaching from each other in an axial direction established by projecting the axis of rotation of the rolling-element bearing onto the housing. The first and second flange parts are hooked to each other by the securing interface and the securing counter-interface.

  • Publication number: 20120321235
    Abstract: A seal arrangement, in particular a cartridge seal, which has a carrier ring that is fastenable to a first bearing ring and a cover ring that is movable in relation to the carrier ring and fastenable to a second bearing ring. The carrier ring carries an elastic part which forms at least one sealing lip that makes sliding sealing contact with the cover ring. The elastic part forms an overhang arranged axially on a radially running portion of the carrier ring, and the overhang radially covers a radial end piece of the cover ring at least partially. The overhang consequently assumes the sealing function of the carrier ring so that the carrier ring can form a sealing gap with the cover ring. The elastic part has to be attached on only one axial side of the carrier ring and thus the fastening region of the carrier ring can be made smaller.
