A bearing assembly includes an inner bearing ring, an outer bearing ring and rolling bodies located between the inner bearing ring and the outer bearing ring. A gap is defined by a radially outer surface of the inner bearing ring and a radially inner surface of the outer bearing ring. The radially inner surface of the outer bearing ring includes a first radial surface portion that is offset a greater distance from a center of the bearing than a second radial surface portion. The first and second radial surface portions are connected by a sloped surface. A sealing arrangement located in the gap. The sealing arrangement includes a first annular body including an elastomeric sealing protrusion to contact the sloped surface of the outer bearing ring.

Wheel bearing

A hollow machine element for transmitting a force and/or a torque is provided. The hollow machine element forms a component of an assembly for measuring the acting force and/or torque by using inverse magnetostrictive effect. The hollow machine element extends along an axis and has a cavity that extends along the axis. The machine element includes at least one magnetization region for magnetization, and which includes a magnetostrictive material. A magnetic field measurable via the assembly can be caused by the magnetization and by the force and/or by the torque. The magnetization region is directed toward the cavity and has an axially central segment, in which the magnetization region is arranged at a radial distance from a ferromagnetic region of the machine element to define a gap therebetween. The gap may be empty or filled with insulation, to provide magnetic insulation.
