VCN245-BN- Stainless Iron Return Type Handle-free Index Plunger

Introduction to Non-Knob Indexing Pins

●Product Introduction

  VCN245-BN is knobless spring return index plunger, also known as automatic spring locating plunger. The body is stainless iron, while pin and spring are stainless steel. External thread at the bottom for mounting. Without external operating knob, the spherical pin retracts automatically when pressed by workpiece. After pressure disappears, the spring pushes the pin out for positioning. Suitable for automatic alignment mechanisms without manual operation. It can be installed with press-fit collar, widely used as built-in positioning parts for automation equipment and molds.

●Structural Features

1. Knobless automatic return designNo pull knob. Pin retracts under workpiece contact pressure and springs back automatically, ideal for fully automatic cycling mechanisms.

2. Bottom external thread mountingMetric thread at bottom for screw fixing; optional press-fit collar for interference installation, flexible assembly methods.

3. Premium material combinationStainless iron body provides high wear resistance; stainless steel pin and spring offer good rust resistance for long-cycle operation.

4. Spherical guiding tipRounded ball head ensures smooth entry, reduces impact abrasion and avoids jamming during alignment.

5. Multiple standard sizes availableStandard and extended L versions are available, various pin diameters and strokes to meet different stroke and load requirements.

●Typical Applications

1. Automated Production Line MechanismAutomatic positioning for cyclic workstations, stop limit for conveyor without manual intervention.

2. Built-in Mold Limiting ComponentsAuto-locking for mold sliding blocks and core-pulling structures.

3. Automatic Tooling & Pneumatic FixturesWorkpiece automatically pushes the pin away and gets locked in place.

4. Rotary Indexing Equipment & TurntablesIntermittent positioning for rotating indexing turntables.

5. Precision Instruments & Sliding AssembliesGear positioning for sliding components and limit lock for small transmission mechanisms.
