Description
Product Overview
The VCN250-BNK Return Type Indexing Hand-Retractable Plunger is a high-precision mechanical positioning component purpose-built for industrial purchasers requiring accurate, repeatable indexing and rapid locking operations in automated and manual manufacturing workflows. This premium spring loaded indexing plunger features an ergonomic T-type handle, a reliable spring-loaded return mechanism, and full stainless steel internal construction, enabling single-handed operation to retract or reset the plunger into positioning holes for instant workpiece indexing or secure locking. Designed to solve core challenges such as low positioning accuracy, frequent component failure in high-cycle operations, and poor adaptability to harsh environments, this reset type indexing plunger is an indispensable positioning solution for enterprise manufacturing clients across precision-driven sectors.
Key Features & Industrial Performance Advantages
Ergonomic T-Handle & Single-Action Rapid Operation
This hand-retractable indexing plunger is engineered with an ergonomic T-handle made from high-strength Nylon6, enabling comfortable, non-slip grip and single-handed pull-and-twist operation for instant locking or release. This intuitive design cuts indexing and tool changeover time significantly, streamlining production workflows and reducing operator fatigue in high-frequency use cases.
High-Precision Indexing & Stable Locking Performance
Featuring a precision-machined plunger and spring-loaded locking structure, this T-handle precision indexing plunger delivers exceptional indexing accuracy of ±0.1mm, ensuring repeatable, consistent positioning even after tens of thousands of operation cycles. Select models include an anti-release safety mechanism to prevent accidental disengagement, enhancing operational safety and reducing the risk of production errors.
Corrosion-Resistant & Long-Lasting Construction
The threaded shell, plunger pin, spring, and lock nut are all manufactured from high-grade stainless steel, delivering excellent corrosion, wear, and rust resistance for use in humid, high-temperature, or sterile clean environments. With hardened contact surfaces, the plunger offers a service life exceeding 100,000 operation cycles, with an operating temperature range of -50°C to 200°C and optional IP65 protection for dust and water ingress resistance.
