Indexing plungers GN 817.3 realize a reasonable priced precision locating when guide bushes DIN 179 are used.

For this purpose a guide bush DIN 179 is used as guide, 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 F7) 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.
