An electric motor manufacturer needs precise information about the dimensions of tapered roller bearings in order to be able to install them more precisely with the help of shims (washers). This precise installation enables optimal power transmission as well as a maximization of the bearing life and thus a reduction in complaints. With evoChK it is now possible to measure the delivered tapered roller bearings to +/- 0.015mm with the help of an optical distance measuring device.

The confocal displacement sensor used works independently of the surface.

To do this, the bearing is placed in the measuring station, rotated by a motor, measured and then labeled. The measured data are visualized on a screen.
