Our pull ring indexing plungers are high-performance spring-loaded locating components designed to lock, align, and position moving mechanical parts. Unlike knob-style plungers, the integrated stainless steel pull ring allows for easy operation with a finger loop or can be connected to a remote cable/lanyard system for automated or hard-to-reach locking mechanisms.
They are widely utilized in many industrial and commercial applications:
Industrial Jigs, Fixtures & Tooling: Ideal for fast adjustments and repeatable positioning of workpieces during CNC milling or assembly.
Special Vehicles & Agricultural Machinery: Used to secure adjustable panels, sliding drawers, fold-down steps, and rotating arms.
Medical & Rehabilitation Equipment: Provides safe, quick-release height and length adjustments on specialized beds, chairs, and rehabilitation machines.
Material Handling & Warehouse Systems: Perfect for securing conveyor guide rails, telescoping tubes, and modular racking.
Convenient Ring-Pull Mechanism: The ergonomic pull ring design allows operators to quickly retract the plunger pin with a simple finger pull—no additional tools required.
High-Tensile Spring Load: Built with an optimized internal spring that provides consistent holding force, ensuring the pin stays securely engaged under heavy industrial vibrations.
Robust Steel & Stainless Steel Construction: Available in high-grade carbon steel (black-oxide finish) or heavy-duty stainless steel (AISI 303/304/316) for superior rust and corrosion resistance.
Precision Threading: CNC-lathed threads guarantee smooth installation and seamless engagement inside standard tapped holes, minimizing thread wear over time.
Optional Locking (Rest) Positions: Available in both standard spring-return and lock-out (rest position) designs, where pulling and rotating the ring keeps the pin retracted.
We are a direct source manufacturer with over a decade of dedicated experience in precision CNC machining and industrial hardware fabrication.
