GN817.3 Indexing Plungers, for Precision Locating

These indexing plungers have been developed to enable precise locating when guide bushes GN770 are used.

For this purpose as a rule, as a plain guide bush (Type A), is used whereby the dimension l3 of the plunger determines the length of the bush.

The precise location is, therefore, not dependent on the guide pin in the plunger, but on the accuracy of the guide bush (bore tolerance G6) and the plunger (tolerance h7). Both components are hardened and ground. It goes without saying that the bush length also influences the accuracy of the positioning.

Type C with rest position is used in such applications where the plunger must not protrude continually. In that case the knob is retracted and afterwards turned by 90. A notch is provided for the key to prevent the plunger from turning by error or vibration.
