As the name suggests, Gear PCD Run Out Checking Device is applicable for inspecting the run out of pitch circle diameters of a gear. The gear to be inspected is mounted on an arbor, which can be either a concept hydraulic expanding arbor or on a taper arbor.

This is a high precision measuring unit with a repetitive accuracy of less than 0.002 mm. The base, the table the tailstock and the head care made cut of close- grained casting. The base is having a box structure sufficiently ribbed for rigidity. Pillar and other ware part are made out of alloy steel and are hardened appropriately.

The arbor along with the gear is in turn mounted between center of the device. Loosening the knob could move the tailstock. Further adjustment can be carried out using knob 2. The gear can be positioned to the center of the ball by rotating the knob 3. The head 4 can be moved up or down by rotating handle 5 to pre- load the dial. When lever 6 is moved, the dial retracts, the gear is indexed and the lever 6 operated to obtain reading.
