Abstract

A method for determining at least one preloading force (K) acting between a carrying body (7) and a rolling-element bearing (2) of a bearing assembly (1), 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 (3). The sensor device is arranged in or on the rolling-element bearing in an installation position (E1) and is coupled to an evaluating device (10) 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.
