This document refers to the product “Mining Belt Conveyor Tapered Idler Roller (Φ159 / 159 mm)” manufactured by Huaibei Hezhong Mechanical Equipment Co., Ltd..

The tapered idler roller is an important component used in mining belt conveyor systems. It is designed to support the conveyor belt, enhance belt tracking stability, and reduce deviation during operation.

Due to its tapered structure, the roller helps guide the belt back to the center position automatically, improving operational stability and reducing wear on both the belt and roller system. It is widely used in heavy-duty material handling environments such as coal mines, ports, metallurgy, and power plants.

The product is manufactured in accordance with relevant Chinese mining industry standards and internal technical specifications, ensuring reliability, wear resistance, and long service life under harsh working conditions.

In international engineering practice, similar conveyor components are commonly aligned with global standards such as:

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

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

DIN 22107 / DIN 22112 (Germany) for conveyor roller structure and dimensional standards

This product is a mechanical conveyor component rather than a safety certification item, used for belt support and alignment in industrial conveyor systems.
