Abstract: A rolling-element bearing includes a first bearing ring, a second bearing ring, and a seal unit formed in a multiple-piece manner, the seal unit including an at least part-ring shaped main element which is freely rotatable with respect to the first bearing ring and the second bearing ring and at least one seal lip. In addition, the main element and the seal lip are exchangeably connectable to each other.

Abstract: A seal unit for a rolling-element bearing having an inner bearing ring and an outer bearing ring. The seal unit includes an at least part-ring shaped element having a seal lip, the at least part-ring shaped element is configured for attachment to the inner bearing ring, and the outer bearing ring is tiltable through a limited angle with respect to the inner bearing ring. Also a rolling-element bearing having such a seal unit.

Abstract: A rolling-element bearing including a seal unit, the rolling-element bearing having at least one bearing ring and a further bearing ring tiltable with respect to the at least one bearing ring by a limited angle, and the seal unit having an at least part-ring shaped element attached to the bearing ring. The at least part-ring shaped element delimits a labyrinthine seal gap and corresponds to a first delimiting element, the rolling-element bearing further includes a second delimiting element and a third delimiting element, the third delimiting element being attached to a bearing cage, and the seal gap extends at least partially between the first delimiting element, the second delimiting element and the third delimiting element.

Abstract: A bearing unit rotatably supports a shaft of a pressure generating device, such a boost pressure generating device of an internal combustion engine. The bearing unit includes at least a first rolling-element bearing and a second rolling-element bearing, each rolling-element bearing having an inner ring and an outer ring. An annular space is defined between the respective inner and outer rings and rolling elements are disposed in the annular space. At least one volume element is disposed in the annular space and at least partially fills the annular space in an axial area.

Abstract: In a device (1) for cleaning a window (2) or a lens of a motor vehicle, a wash nozzle (5) is of spherical design and is held in a ball socket (13) of a nozzle stem (4). The wash nozzle (5) produces a fan-type jet (6) and can be adjusted by an angle of inclination ? and a tilting angle ? in relation to the nozzle stem (4). The device can be freely adjusted to different designs of the motor vehicle.

Abstract: A nozzle device (3) for cleaning a window (2) has a plurality of nozzle openings (15, 16). One nozzle opening (15) which is embodied as a localised jet nozzle is arranged on the end of a groove-type recess (18) of the nozzle body (6). The nozzle body (6) is pressed into a nozzle housing (4) guiding a washing liquid. In this way, the nozzle opening (15) is formed partially by the nozzle body (6) and partially by the nozzle housing (4). The nozzle device (3) is thus especially cost-effective.
