snap gauge for taper

MGK132 Taper Gauges are designed to probe tapered bearing seats in production facilities, which is important to ensure compatibility between the fit surfaces of the bearing and bearing seat. With a reproducibility factor of less than 1μm, external tapers are measured with a taper angle of 0° to 6° and a taper diameter of 90mm to 360mm.

The gauge is positioned on a taper through a stop on either the front or the back, and it rests on the workpiece through four robust, ground and lapped ledges at an angle of 90°. Between the four ledges, a measurement slide runs and a dial gauge works against the slide while displaying the deviation of the taper diameter.
