TADAAH 0801012 Guide/Pivot Pin for Collet Opening/Closing Unit for Gildemeister GM20 – version-specific variants
(Incl. Tax: €146.40)
Guide/pivot pin for the collet opening/closing unit for Gildemeister GM20 multi-spindle automatic lathes. Supports linkage alignment, reduces play and vibration, and improves clamping repeatability in serial production. Recommended for preventive maintenance whenever clearance, scoring or sticking appears.
Note: springs, disc springs, bearings and other wear parts are not included unless explicitly stated.
Guide/pivot pin for the collet opening/closing unit for the Gildemeister GM20 multi-spindle automatic lathe. The pin acts as a centering and guiding element for the linkage that drives the collet movement, helping keep alignment, minimizing play and supporting repeatable bar clamping.
In serial production, the condition of the collet unit directly affects grip accuracy, surface finish and cycle stability (drilling, turning, milling and combined operations). A worn pin (scoring, clearance, damaged thread) may cause micro-misalignment leading to vibration, out-of-round parts, marks and reduced repeatability.
Use & maintenance tips: during planned stops check smooth motion, no sticking, and thread integrity; inspect mating seats for seizure marks, clean and lubricate per machine procedures. When replacing, always verify compatibility with your unit version (material and dimensions) and assess the condition of coupled wear parts.
Typical applications: automatic turning and high-volume production for automotive, fittings and valves, small metal parts, hydraulic/pneumatic components, electromechanics, general machining and subcontract turning.
Wear parts – Collet opening/closing unit (Gildemeister GM20)
| Spare part | Function / notes | Type |
|---|---|---|
| Guide/pivot pin (item) | Guides and aligns the opening/closing linkage; keeps the mechanism concentric | Structural |
| Helical springs | Return force and motion stability; replace if load loss or fatigue | Wear |
| Disc springs (Belleville) | Preload and clamping force; check for flattening and deformation | Wear |
| Bearings | Reduce friction and play; replace if noise, seizure or excessive clearance | Wear |
| Bell housing / guide body | Houses and transfers motion; inspect for scoring and ovality | Wear |
| Pusher nose / thrust element | Transfers force to the collet; replace if profile wear is visible | Wear |
| Closing lever / rocker | Mechanical actuation; inspect for cracks and worn seats | Wear |
| Pins, shims, circlips | Retention and adjustment; replace if deformed | Wear |
| Fasteners and set screws | Clamping and positioning; use threadlocker where required | Wear |
