A device for detecting and monitoring damage to races (3 & receiver 24) or adjacent areas on the rings (1 & 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 & 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. - 8 -

Why it's free to use
- Filed August 18, 1992 and granted April 21, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 18, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 18, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
