Description
Product Overview
Engineered for seamless, repeatable industrial positioning, our return type hand-retractable indexing plungers (also known as spring loaded retractable locating pins, non lock-out indexing plungers, and quick-release knob plungers) are a high-performance positioning solution from VEICHU. Built with full stainless steel core components and an ergonomic Nylon 6 knob, this VCN220-BNK series delivers consistent automatic return functionality and smooth hand-operated retraction, making it the top choice for industrial equipment manufacturers, precision engineering firms, and industrial component distributors requiring reliable, high-cycle positioning components. Available in a wide range of metric thread sizes, these plungers are optimized for rapid, tool-free operation in diverse industrial environments.
Key Features & Industrial Performance Advantages
Automatic Return Mechanism for Continuous High-cycle Operations
The core design of our return type spring loaded plungers features a precision-calibrated automatic return structure, which retracts smoothly via manual knob operation and automatically resets to the working position when released, eliminating the need for manual repositioning. This design delivers an indexing accuracy of ±0.1mm, ensuring consistent positional repeatability even in high-frequency operating environments with over 100,000 cycles, drastically reducing operator fatigue and improving production line throughput.
Full Stainless Steel Construction for Harsh Environment Compatibility
The threaded shell, locating pin, internal spring, and lock nut are all manufactured from high-grade stainless steel, paired with an impact-resistant Nylon 6 handle. This all-stainless steel wetted parts design delivers exceptional corrosion resistance, rust prevention, and wear tolerance, making it suitable for humid, high-temperature, sterile, or chemically exposed environments. The plungers maintain stable performance in operating temperatures ranging from -50°C to 200°C, with optional IP65 sealing available for dust and water ingress protection.
Ergonomic & Versatile Design for Universal Industrial Fit
Our hand-retractable stainless steel indexing plungers are available in standard thread sizes from M10 to M24, with a compact, space-saving mounting design that fits most standard industrial fixture and equipment mounting holes. The ergonomic knob is available in black, blue, and red color options, with a one-hand pull-and-release operation that enables full retraction and reset in under 1 second, far outperforming traditional threaded fasteners in rapid changeover applications.
