ABSTRACT:
A device for measuring wear in large roller bearings that have two bearing rings (1 & 2) with space accommodating the rollers (3) between them. The device has an indicator that indicates a prescribed deflection between the rings and a probe (9) that is accommodated in an opening (10) in the outer bearing ring (2) with the end (11) of the probe able to come into contact with one of the surfaces of the inner bearing ring (1). The object is a device that will provide accurate and reliable indications of bearing wear even after years of use, that will be simple in design, and that cannot be damaged or destroyed by outside forces. The inner bearing ring accordingly has a groove (12) facing the probe, and the end of the probe extends into the groove. The surfaces of the groove are as far from the end of the probe as the maximal permissible depth of the wear on the bearing.
