An electric motor manufacturer requires precise information about the dimensions of tapered roller bearings in order to be able to install them more accurately with the aid of shims. This accurate fitting allows for optimal power transmission and maximizes bearing life, thus reducing the number of complaints. With evoChK it is now possible to measure the delivered tapered roller bearings to +/-0.015mm, using an optical distance measuring device.

The confocal displacement sensor used operates independently of the surface.

For this purpose, the bearing is inserted into the measuring station, rotated by motor, measured and then labelled. The measured data are visualized on a screen.
