Technopolymer indexing plunger GN 823

zinc-plated steelstainless steellockable

Product overview
Indexing plunger GN 823 is used to lock or index moving parts (e.g. carriages in guides). The plunger retracts when the actuation lever is pressed. Version C also allows pull actuation and includes a locking feature that secures the plunger in the retracted position.

Construction / materials

• Body (guide): Steel (ST) zinc plated, blue passivated; Stainless steel (NI) 1.4305 (AISI 303)
• Plunger: Stainless steel 1.4305 (AISI 303)
• Lever: Plastic, polyphthalamide (PPA), glass-fiber reinforced; color: SW (black)
• Compression spring: Stainless steel 1.4310 (AISI 302)
• RoHS: RoHS compliant

Variants & coding

• Form: B = without locking in retracted position; C = with locking in retracted position (actuable by pulling)
• Thread code: R = standard thread; F = fine thread

Accessories (examples)

• Positioning bushes GN 412.2 (with collar)
• Positioning bushes GN 412.4 (with collar, stainless steel)
• Positioning bushes GN 412.3 / GN 412.5 (with lead-in cone)
• Spacer rings GN 609.5 (stainless steel)
• Retaining brackets GN 412.1 (zinc die-cast) / GN 612.1 (steel / stainless steel)
• Flat hex nuts GN 909 / GN 909.5 (stainless steel)

Dimensions (selection)
Available diameters d1 (examples): 4, 5, 6, 7, 8, 10 mm. Available lengths l1 depend on diameter and variant.

Compliance & ordering

• RoHS compliant
• Example weight (typical variant): approx. 0.026 kg
• Ordering code example format: GN 823 - d - l - form - thread - material - lever color (e.g. GN 823-6-7-B-R-ST-SW)

Application notes
Suitable for industrial locking and indexing tasks where repeated positioning or frequent disassembly is required. Multiple material and thread options enable selection for corrosion resistance and mechanical requirements.
