VCN325 POM Threaded Type Conveyor Ball Rollers

POM Threaded Ball Plunger Product Introduction

●Product Overview

  This product is a springless threaded ball plunger with housing fully made of POM (Polyoxymethylene) engineering plastic. The threaded outer shell is integrally injection-molded from high-rigidity POM material, fitted with a freely movable stainless steel ball at the top, with no internal compression spring inside the structure. It presents an all-white appearance with complete external thread structure.

●Key Features

1. Outstanding POM Material Performance: 

2. POM features inherent self-lubrication with an ultra-low friction coefficient, enabling smooth sliding of the steel ball inside the housing. It delivers exceptional wear resistance and anti-fatigue performance; the housing resists cracking and thread stripping under long-term reciprocating contact. The material withstands weak acid and alkali corrosion without rusting, making it suitable for humid environments and mild chemical media. As an electrical insulator with zero magnetism, it avoids signal interference to electronic components and precision sensors.

3. Soft POM Thread Prevents Mating Workpiece Damage: 

4. The soft POM external thread eliminates scratching to mating workpieces including aluminum parts, plastic housings, anodized panels and PCBs during tightening. No extra gaskets are required, and no indentations, paint peeling or surface abrasion will occur during locking assembly.

5. Ultra-Lightweight & Silent Operation:

6.  It drastically reduces weight compared to stainless steel spring ball plungers to lower dynamic load on moving equipment. Contact friction between steel ball and POM housing generates minimal noise with no metallic impact or spring vibration sound, ideal for silent miniature instruments and low-load automation equipment..

7. Integral Dustproof Corrugated Shell Design: 

8. The thickened corrugated threaded shell forms a compact one-piece structure that blocks dust and fine debris from entering the internal cavity, preventing ball sticking and maintaining consistent sliding performance for long-term continuous use.

●Application Scenarios

1. Plastic & Aluminum Profile Static Automation Tooling: 

2. Plastic mold fixed positioning accessories, stationary indexing locating for aluminum alloy frames, fixed limit stops on production lines; protects anodized aluminum and plastic surfaces from assembly scratches.

3. Magnetically Sensitive & Non-Conductive Equipment: 

4. Magnetic laboratory testing instruments, precision magnetic detection equipment, positioning parts for carbon fiber and plastic frames; non-magnetic design eliminates detection data distortion caused by metal springs.

5. Light-Duty Manual Fixed Tooling & Toy Components: 

6. Miniature stationary manual fixtures, permanent mold positioning blocks, precision fixed gear snaps for toys; lightweight construction reduces operator handling burden with zero spring maintenance

7. Precision Electronic Testing Equipment: 

8. Testing jigs, fixed-position tooling fixtures, static housing latches, PCB inspection fixtures; ideal for insulation-required equipment to eliminate short-circuit risks and magnetic interference on circuit board components.
