摘要:
A seal assembly seals a first portion of a machine part relative to a second portion of the machine part. The seal assembly includes at least one seal element that contacts the machine part or contacts a component connected with the machine part or that extends with a gap relative to the machine part or to the component connected with the machine part. At least one of the seal element, the machine part and the component connected with the machine part is provided or coated with a material, which has super hydrophobic properties, in the area of the seal element.

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.

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.

A rolling-element bearing includes a first bearing ring (2) and a second bearing ring (4) opposing the first bearing (2) in a radial direction (3). A sealing element (6) of the rolling-element bearing includes a radially-encircling seal support (8) extending in the radial direction (3) by a predetermined distance towards the second bearing ring (4). The seal support (8) is interference-fit and removably attached to an axial end side (9) of the first bearing ring (2). A sealing lip (10) is attached to the seal support (8) and extends from an end of the seal support (8) opposite the first bearing ring (2) in the radial direction (3) up to a mating surface (12), which is part of the second bearing ring (2).
摘要:
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.

摘要:
A device for cleaning a surface of a component includes a high voltage source having a cathode configured to be electrically connected with the surface of the component. An ionization electrode includes at least one individual electrode configured to be electrically connected with an anode of the high voltage source. A movable carriage moves the ionization electrode relative to the surface of the component so that an electric field generated between the ionization electrode and the surface of the component is also moved relative to the surface of the component.
