Information

Indexing plungers GN 824 have a plunger pin with square cross-section, a latching surface on one side and a chamfer on the other. When moving in the direction of the chamfered pin, the plunger pin passes over grooves and edges, as the chamfered pin moves the plunger pin into the guide. The plunger pin automatically latches into place when moved toward the latching surface. The latching can be released by pulling the knob.

Type C / CK indexing plungers with rest position are used for applications when the plunger pin is temporarily not to engage. In that case, the knob is retracted and afterwards turned by 90°. A notch keeps the plunger in this position.

When the grub screw is not tightened, the orientation of the bevel can be freely adjusted over a range of 360°. This can be identified by the marking on the indexing plunger guide.
