Abstract: A piston bearing unit having an actuating piston which has a receiving region. The actuating piston is designed to actuate an element by way of a linear movement. The piston bearing unit also comprises a bearing having a first raceway and a second raceway, wherein the bearing is designed for mounting the actuating piston rotatably with respect to the element. The first raceway and the second raceway are at least partially accommodated in the receiving region.

Abstract: A sealing assembly includes a seal support having a support ring made from an elastomeric material, at least one seal element having a ring made from a polymer material, and an abutment ring against which a radial portion of the seal element axially abuts. The seal element is connected in a materially-bonded manner to the support ring along a first radially outer portion of the seal element, and the seal element axially abuts on the abutment ring along a second radially inner portion of the seal element. The seal element and the abutment ring are free of any connection along the second radially inner portion of the seal element.

Abstract: A seal to seal a gap between a rotatable component (4, 18) and a non-rotatable component comprises: A fastening section adapted to be fixedly mounted in relation to the non-rotatable component, a sleeve-like section (3) adapted to be mounted around the rotatable component (4, 18), a resilient section (7) between the sleeve-like and fastening section comprising an arcuate portion (8), and in an unmounted condition, the sleeve-like section (3) has an inner diameter, DSEAL, with a predefined magnitude relative to an outer diameter of the rotating component, DSHAFT, such that 0.9?DSEAL/DSHAFT?1.1.

Abstract: 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.
