Description
Product Overview
The VCN218-BS/MBS series all stainless steel mini hand-retractable plungers (also named manual indexing pins, quick-release positioning plungers) are professional-grade precision mechanical positioning components, engineered exclusively for industrial manufacturing enterprises, automation solution providers, and precision machinery fabricators. Built with full stainless steel construction, these hand-operated indexing plungers deliver reliable, repeatable positioning and locking performance for applications requiring rapid, precise workpiece alignment and fixture adjustment. The core working principle relies on a smooth pull-and-twist manual operation to engage or disengage the precision-machined pin from locating holes, enabling one-step locking and release for improved operational efficiency in high-demand industrial environments.
Key Features & Industrial Performance Advantages
Full Stainless Steel Construction for Harsh Environment Adaptability
Every core component of the mini hand-retractable plungers – including threaded shell, positioning pin, and operating handle – is manufactured from premium stainless steel, delivering exceptional corrosion resistance, rust protection, and chemical stability. This design makes the plungers suitable for humid, outdoor, or high-cleanliness production environments, with an operating temperature range from -50℃ to 200℃, and optional IP65 protection for dust and water ingress resistance.
Ultra-High Precision Indexing for Consistent Industrial Performance
Featuring a precision spring-loaded structure and tight tolerance fit between the plunger pin and locating holes, the VCN218 series achieves an indexing accuracy of ±0.02mm, ensuring stable locking and repeatable positioning even under continuous high-frequency use. The hardened contact surface extends the service life to over 100,000 operation cycles, minimizing maintenance downtime for industrial production lines.
Ergonomic Hand-Retractable Design for Rapid Operation
The integrated manual handle enables one-handed pull-and-twist operation, completing locking or unlocking in a single motion, which significantly boosts work efficiency for quick tool changes, fixture adjustments, and rotary table indexing. The compact mini design fits into limited installation spaces without compromising operational accessibility.
Standardized Thread Configurations for Universal Compatibility
The series offers both fine thread and coarse thread options, with standardized metric sizes including M8×0.75, M8×1, M10×1, M12×1.5, and M16×1.5 for fine thread, and M8×1.25, M10×1.5, M12×1.75, M16×2 for coarse thread, ensuring seamless compatibility with most global industrial equipment interfaces.
