Product description

Information

Indexing plungers GN 817.5 make highly accurate positioning possible, by utilizing press-fit drill bushings DIN 172 / DIN 179 as a guide. The utilization of the drill bushing and either the guide bushings GN 172.1 or GN 179.1 provides two mating parts for the indexing plunger pin.

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

The lock-out type C is used for applications where the plunger pin needs 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 the retracted position.

Construction and Assembly Instructions

Sketch GN 817.5

The length l7 is determined by the penetration depth of the plunger pin into the cone of the bushing.

The length l8 must ensure that the plunger pin fully disengages. Bushing length and plate thickness plus any gap can then be selected within certain margins.

When engaged, the pin hast to have a minimum remaining stroke of 0.5 mm to make sure that the conical section of the pin is located in the cone of the guide bushing without clearance.
For each plunger pin diameter d1, two different pin lengths l1 are available.

For a safe remaining stroke: l9 = l1 - 0.5 mm
For mounting the bushings with tolerance n6, a hole with tolerance H7, corresponding to the external diameter, is usually provided.
