Product description
Information
Indexing plungers GN 817.3, together with guide bushings DIN 172 / DIN 179, enable precise positioning.
The bushings are used to guide the plunger pin as well as for the indexing bore. The plunger pins and bushings are hardened and ground. Larger guide lengths further increase the precision.
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
|
Two different plunger pin lengths l1 are available for each indexing plunger diameter d1. The length l3 must ensure that the plunger pin fully dis-engages, bushing length and plate thickness plus any gap can then be selected within certain margins. For mounting bushings with tolerance n6, a hole with tolerance H7 corresponding to the external diameter is usually provided. |
