Indexing plungers GN 617: pin diameter 5 to 10 mm, thread, A/F, lengths and spring load (steel and stainless) — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/indexing-plungers-gn-617/ (sheet CC BY 4.0) Basis: Ganter's GN 617 table (d1 to l7, A/F, spring loads) agreeing with the Elesa sheet and J.W. Winco's data sheet on every number, Winco for the stainless loads; labels as printed (Ganter does not define l1 to l7); numbers only Catalog version: 2026-10-20 Sizes: see table below - GN 617 is the indexing plunger: a threaded body with a spring-loaded hardened pin that is pulled by a knob to release the indexed part and drops into a hole in the index plate when released. This is Ganter's 'without rest position' version (the pin cannot be parked retracted); GN 617.1 is a lock-out version and GN 817 the version with rest position for higher axial loads (Ganter points to GN 817 for higher forces). Versions: A with plastic knob, AK with knob and lock nut, G without knob (threaded drive rod d4, for your own knob or a mechanism), GK the same with lock nut; AN / AKN are stainless-knob variants. Sizes: pin Ø 5, 6, 8, 10 mm. - The dimension columns are exactly as Ganter prints them (d1 pin, d2 thread, d3, d4 only on G / GK, e, l1 approximate, l2 to l7, A/F) because Ganter's page does not define l1 to l7. A cross-check is possible only on e: it equals A/F divided by cos 30° (across corners of the lock-nut hex) on every size. The Elesa sheet prints the same numbers under different column labels (l5 = 6 / 10 / 12 / 12 for the G / GK rod length, l6 = 15 / 17 / 23 / 30, no l7) and an extra last value per row that is not labelled in the text read, so l-labels are not comparable between makers; the values are. Spring loads steel (initial / end) agree between Ganter, Elesa and Winco (7 / 17, 9 / 24, 11 / 30, 19 / 45 N); the stainless loads are Winco's (6 / 15, 8 / 21, 9 / 26, 17 / 40 N). Loads are approximate. - The mating hole: Ganter gives the pin −0.02 / −0.05 mm (d1) and a guide (index plate) bore H7. That pair is in the mating table below; the thread d2 is a fine thread (M10 × 1, M12 × 1.5, M16 × 1.5, M20 × 1.5), so the mounting hole is not an ISO coarse tap drill. A distance bushing GN 609.5 (stainless) is offered for mounting on thin sheet. - No file: which of l1 to l7 is the thread length, the knob offset or the pin stroke is not stated, so a drawing would be invented. Ganter publishes CAD per part on the GN 617 product page (linked).
