Product Description

GN817.5 Indexing Plunger, for Precision Locating, Conical Plunger

These indexing plungers, GN 817.5 allow highly accurate positioning, with the guidance made by positioning bushings DIN172 or DIN179 with cylindrical bore. The actual indexing bore is fitted with positioning bushings GN172.1  or GN179.1 with conical bores.

The conical shape of the indexing pin and indexing bore makes the positioning virtually clearance-free and therefore highly precise.

Type C is used for such applications where the plunger has to stay in its retracted position. To achieve this, the knob is rotated by 90° degrees after being retracted. A notch keeps the plunger in this position.


Steel ST - blackened,

Plunger - hardened and ground

Knob - Plastic (Polyamide PA), black, matt, not removable
