A clamping device () for receiving and for the clearance-free prestressing of a wheel bearing comprises a clamping mechanism () which radially prestresses the wheel bearing () from the outside.

Device for pre-stressing a wheel bearing

A process for protecting the surface of a roller bearing against corrosion. The roller bearing is provided with a thin protective coating of a powdered coating material or of a wet coating material and then the bearing is inductively heated, at the coated surface thereof, in the range of 200.degree. C. to 300.degree. C. for a few seconds to cure the coating material. The bearing is thereafter cooled. The wet coating material is based on inorganic substances and is electrically conductive.

Process for protecting roller bearings against corrosion

A process for applying one or more inner races on a shaft or a hub of a rolling bearing unit that allows the individual components to be produced with relatively wide tolerances. It is particularly useful in a wheel bearing. The process includes determining the force displacement characteristic on the bearing elements at stages of applying the one or both bearing inner races to the hub at the time the first applied bearing race contacts a stop or shoulder on the hub and then during the cold forming of a collar on the hub securing the inner races on the hub. The force displacement characteristic is monitored and may be compared with predetermined stored values.

Process for the production of a rolling bearing unit comprising a

A process for determining the prestress of antifriction bearings which are preloaded against each other or installed with an initial stress, and permitting a reliable determination as to the prestress actually present in the bearing. The initial stress is determined in connection with the elastic behavior (elastic deformation) of the bearing, by first, applying a first force F.sub.1 to the bearing as it rests on a flange or bearing ring, and measuring the elastic deformation S.sub.1 resulting therefrom. Second, another (higher) force F.sub.2 is applied to the bearing and again the elastic deformation S.sub.2 resulting therefrom is measured. Thereupon, the difference between the elastic deformations (S.sub.2 -S.sub.1 =.DELTA.S) is determined and the existing initial stress is found by comparison with the elastic characteristic (calculated or empirically determined) of the bearing.
