Description
Product Overview
The VCN217-BNK hand retractable indexing plunger is a professional-grade, return-type precision positioning component, purpose-built for industrial applications requiring rapid, repeatable indexing and secure positional locking. Also known as a manual indexing pin or quick-change positioning plunger, this full stainless steel unit features an ergonomic aluminum handle and spring-loaded return design, enabling one-handed operation to engage or disengage the plunger pin from locating holes in seconds. It is the ideal positioning solution for industrial manufacturing enterprises, automation system integrators, and precision machining workshop operators, with standard thread sizes ranging from M6 to M12 to fit universal industrial mounting requirements.
Key Features & Industrial Performance Advantages
One-Touch Manual Operation for Maximized Work Efficiency
Unlike fixed positioning pins that require full removal for adjustment, our return type spring loaded indexing plunger achieves locking and unlocking via a single pull-and-twist motion, cutting setup and changeover time by up to 70% for machining and automation workflows. The integrated return spring automatically retracts the pin when released, eliminating lost components and streamlining high-frequency adjustment operations.
Full Stainless Steel Construction for Extreme Durability & Environmental Adaptability
The VCN217-BNK features a 304 stainless steel threaded body, plunger pin, and internal components, paired with a rugged aluminum handle, delivering exceptional corrosion resistance and mechanical strength. Validated to operate reliably in temperatures ranging from -50°C to 200°C, with optional IP65 sealing for dust and water ingress protection, this corrosion resistant manual indexing plunger is suitable for harsh outdoor, marine, and cleanroom environments alike. It is tested to withstand over 100,000 operating cycles without loss of locking force or indexing accuracy.
Precision Indexing Performance with Built-In Safety Redundancy
This precision locking indexing plunger delivers ±0.1mm repeatable indexing accuracy, meeting the strict demands of automated production lines and inspection gauges. Its precision-machined locking mechanism ensures stable, vibration-resistant locking in high-shock industrial environments, with select configurations featuring an anti-release safety design to prevent accidental unlocking during operation. The modular design supports full customization of pin diameter, stroke length, and indexing features to suit unique application needs.
