Product Description
Flanged Pull Ring Indexing Plunger Introduction
●Product Introduction
Flanged pull ring indexing plunger is precisely machined from high-quality carbon steel with black oxide anti-rust surface treatment. Equipped with integrated flange mounting plate with bolt holes, it can be directly fastened on sheet metal, machine frames and fixture plates. Two types available: spring return type & self-locking type. Pull the knob to retract the locating pin. For spring return version, pin extends automatically once released. Self-locking version can keep pin retracted until pulled again to release. It is a manual locating fastener widely used for quick positioning and locking on toolings and automation equipment.
●Structural Features
Two types for different working demandsSpring return type: Pin pops out automatically after releasing the pull ring, ideal for frequent loading/unloading and short-time locking. Self-locking type: Maintains pin retracted status after pulling, no need to hold continuously, perfect for long-term unlocked state.
Flange mounting baseIntegrated rectangular flange with mounting holes. Direct bolt installation without thread tapping. Stable mounting, easy assembly and maintenance.
Hardened carbon steel for high wear resistanceCarbon steel body with heat quenching treatment. Hardened locating pin resists abrasion and deformation after repeated operation. Black oxide finish provides anti-rust and oil-resistant performance.
User-friendly pull knob operationKnurled pull ring enables tool-free manual operation to retract/extend pin, improving efficiency for workpiece locking and release.
Smooth & reliable positioningPrecision spring and finely machined pin ensure stable stroke and smooth movement without jamming. Excellent repeat positioning accuracy with consistent clearance.
