GN 817.5 Indexing Plungers for Precision Locating, Plunger Pin Conical

Product description
Information
Indexing plungers GN 817.5 allow highly accurate positioning, with the guidance made by the positioning bushings DIN 172 / DIN 179 with cylindrical bore. The actual indexing bore is fitted with positioning bushings GN 172.1 / GN 179.1 with conical bores.
The conical shape of the indexing pin / the 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.

Construction and assembly instructions
|
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. If engaged, the pin must have a minimum remaining stroke of 0,5 mm to make sure that the conical section of the pin is located without clearance in the cone of the guide bushing. |
