PJ Type Poly-V Pulleys for Professional Conveyor Rollers


This product is a high-precision, high-performance plastic Poly-V pulley specifically designed for roller drive in industrial conveyor systems. It strictly adheres to the ISO 9982 international standard and utilizes the PJ type groove specification. Renowned for its exceptional transmission efficiency, stable operation, and long-lasting durability, it stands as the ideal choice for modern production line drive systems.


Core Features & Advantages

1. Standardized Design, Excellent Compatibility & Interchangeability

Strict conformity to the PJ type specifications within the ISO 9982 standard ensures perfect matching with Poly-V belts of the same specification available on the market. This eliminates selection and fitting concerns, facilitating equipment maintenance and spare parts management.


2. High-Precision Grooves Ensure Smooth & Efficient Power Transmission

Utilizing precision molds and manufacturing processes, the pulley maintains a stable groove pitch of 2.34mm. This high-precision design effectively prevents belt misalignment and wear, enabling smooth power transfer, significantly reducing vibration and noise, and enhancing the overall operational quality of the conveyor system.


3. High-Quality Engineering Plastic Material, Lightweight & Durable

Compared to traditional metal pulleys, this product is manufactured from high-strength engineering plastic, offering lightweight properties, low inertia, and corrosion resistance. This helps reduce energy consumption during roller startup and operation, while also avoiding rust issues, making it particularly suitable for industries with cleanliness requirements such as food, packaging, and electronics.


4. Integrated Design, Ready-to-Use

The product features a unitary design and **can be equipped with standard bearings and protective end caps. This integrated structure greatly simplifies the installation process – users can simply press the pulley into the roller tube for quick assembly. The end caps effectively prevent dust, fibers, and other foreign matter from intruding into the bearing, extending the service life of core transmission components and reducing maintenance needs.
