A frictional piece for a wet frictionally engaging device includes an axis of rotation, a lining support, a pair of friction linings, and a plurality of through holes. The lining support is rotatable about the axis of rotation. The pair of friction linings is mounted on the lining support. The friction linings include respective frictional surfaces that face away from each other. The plurality of through holes extends through the friction linings and the lining support between the frictional surfaces. The frictional piece also includes a plurality of channels each fluidically connecting at least two of the plurality of through holes.

A wheel bearing arrangement of a vehicle axle is disclosed. The wheel bearing arrangement includes a wheel bearing, which contains at least two rolling element rows, for supporting a wheel hub which can be driven by a drive element. The rolling elements of the wheel bearing are guided in races of a stationary outer ring, the rotating wheel hub, and a separate inner ring which is allocated to the wheel hub. In the assembled state, the wheel hub of the wheel bearing arrangement and the drive element are operatively connected via gearing. The inner ring has a radially stepped inner contour, the inner contour having two diameters which differ from one another, and are received in a complementarily designed receiving area of the wheel hub. The position of the inner ring is fixed on the end face by a rolling riveted collar of the wheel hub.

A bearing seal () of a rolling bearing configured as a wheel bearing () that is connected between a first rotationally rigid bearing part () and a second bearing part () that is integral with a wheel bearing flange (), between which rolling bodies () are guided. The bearing seal () includes a splash plate () configured as a preseal, which is supported on an axially and radially oriented contour () of the second bearing part (), and together with the wheel bearing flange (), axially defines a catch channel (). A seal fitting () is fixed to the first bearing part () by a reinforcement (), wherein the reinforcement () is enclosed by an elastic sealing material (), at least in some areas, from which sealing lips () are formed, which are grindingly or non-grindingly associated with the splash plate (). Between the splash plate (), which abuts, in a line or surface contact, the radially oriented wheel bearing flange () via a support zone (), and the sealing fitting (), a sealing labyrinth () is provided. By way of a resiliently flexible fastening section (), the splash plate () is pressed onto the cylindrical contour () of the second bearing part () and is pre-stressed in an end position.
