A method for determining at least one preloading force (K) acting between a carrying body () and a rolling-element bearing () of a bearing assembly (), which rolling-element bearing is mounted on the carrying body, and the bearing assembly includes the rolling-element bearing and the at least one sensor device (). The sensor device is arranged in or on the rolling-element bearing in an installation position (E) and is coupled to an evaluating device () in a signaling manner. The sensor device senses the preloading force, produces at least one signal (S) in accordance with the preloading force, and transmits the signal to the evaluating device, and the evaluating device evaluates the signal in order to measure the preloading force and the sensor device is permanently decoupled from the evaluating device after the evaluation of the signal.

Method for measuring a preloading force and bearing assembly for performing the method

A cage for a rolling bearing which has pocket-shaped recesses for receiving rolling bodies and at least one guiding means for guiding the cage. The at least one guiding means is detachably connected to the cage. Thus, by design, the structure designed for the guiding of the cage is simple, economical and flexible, and suitable for all kinds of different cage shapes and dimensions.

Cage for a rolling bearing, comprising guiding means

A roller bearing cage for guiding rolling bodies in a rolling body bearing, which has multiple rolling bodies, two cage side elements, between which the rolling bodies are arranged, and which have multiple web appendages to guide the rolling bodies, and multiple connection elements that connect the two cage side elements. The azimuthal position of the connection elements defines a connection area. Exactly one connection element and at least one web appendage are arranged in a connection. The connection element and web appendage are arranged in sections inside a radial interior of the respective cage side elements, the border of which is defined by the positions of the rotation axes of the rolling bodies.

A seal assembly for sealing between two elements, at least one of the elements having a cylindrical surface supporting a seal made of an elastic material provided with a sealing lip bearing against the second element, the improvement comprising that the seal consists of a hollow-cylindrical body from which a sealing lip projects from at least one face and the body bears against the cylindrical surface of the one element and is encircled by an elastic band of polymeric material to hold the body in place.
