This document refers to the product “Mining Belt Conveyor Polyurethane Rubber-Lined Idler Roller (Φ133 / 133 mm)” manufactured by Huaibei Hezhong Mechanical Equipment Co., Ltd..

The polyurethane rubber-coated idler roller is a key component used in mining belt conveyor systems. It is designed to support the conveyor belt, reduce friction resistance, and improve operational stability and wear resistance under heavy-load and continuous working conditions.

The polyurethane coating provides excellent abrasion resistance, corrosion resistance, and impact resistance, significantly extending the service life of the roller while enhancing belt tracking performance and operational efficiency.

The product is manufactured according to relevant Chinese mining industry standards and internal technical specifications, ensuring stable performance in coal mining and bulk material handling environments.

In international engineering practice, similar conveyor components are widely used and generally comply with industrial standards such as:

CEMA standards (USA) for conveyor idler rollers and bulk material handling systems

ISO 1537 / ISO 5048 for conveyor system design and performance

DIN 22107 / DIN 22112 (Germany) for conveyor roller structural and dimensional requirements

This product is a mechanical conveyor component rather than a safety certification item, widely used in mining, metallurgy, ports, and power plant material transport systems.
