Abstract
A device for detecting and monitoring damage to races (3 and receiver 24) or adjacent areas on the rings (1 and 2) in antifriction bearings. The object of the present invention is a device that will not only precisely measure the dimensions of cracks and pits in the race or in the transition between the races and the ring but will also forward the results to the processing equipment with no perforations in the ring and without cables and plugs. One or more sensors (13 and 14) are positioned between the rolling components (5) inside the antifriction bearing, whereby the signals they generate are transmitted electromagnetically to a receiver antenna (23) outside the antifriction bearing.
