Abstract: Rotary joints are disclosed, such as for supplying fluid to a pressure chamber that is disposed between a rotatable component and a stationary component. The rotary joint may include a seal carrier having at least one channel for a fluid connection to the pressure chamber. At least two axially spaced apart sealing rings may be disposed on the seal carrier for a static sealing of the at least one channel. At least one sealing element may be non-rotatably disposed on the seal carrier and configured to form an axial and a radial seal of the pressure chamber. The at least one sealing element may be configured to bear on a ring element that is non-rotatably connected to the rotatable component when pressure is built up in the pressure chamber and the at least one sealing element may have means for reducing the axial pressure exerted on the ring element.

Abstract: A sealing arrangement for a wheel bearing having a first component against a second component which is rotatable relative thereto, the sealing arrangement having a first seal arranged on the first component and a second seal arranged on the second component, the first seal has at least one opening for the passage of air at least in a sealing chamber formed spatially between the two seals, and a fabric element is provided to at least partially expand upon contact with water and thereby to seal the at least one opening.

Abstract: An anti-friction bearing unit (1), configured at least as a two-row anti-friction bearing with at least one outer ring (4a, 4b) and at least two inner rings (5a, 5b), between which rolling bodies (6a, 6b) are guided on raceways of the bearing rings (4a, 4b; 5a, 5b). A clip ring (14) that engages into annular grooves (12a, 12b) of axially extended sections (8a, 8b) of the adjacent inner rings (5a, 5b) is provided for securing an axial position of the inner rings (5a, 5b). The radially pre-stressed clip ring (14) of U-shaped design is arranged in a non-positive manner on an intermediate step (13) of the inner ring (5a) in a pre-mounting position and can be pushed from there into an end position. In matching positions of the flanks (15a, 15b) of the clip ring (14) and corresponding annular grooves (12a, 12b) of the extended sections (8a, 8b), the clip ring (14) latches in a positively locking manner and brings about an axial connection of both inner rings (5a, 5b).
