This document refers to the product “Mining Belt Conveyor Tapered Rubber-Covered Idler Roller (Φ194 / 194 mm)” manufactured by Huaibei Hezhong Mechanical Equipment Co., Ltd..

The tapered rubber-lined idler roller is an essential component of mining belt conveyor systems. It is designed to support the conveyor belt, improve belt tracking performance, and reduce deviation during operation.

The rubber-coated surface enhances friction and wear resistance, helping to extend service life and improve operational stability under heavy-duty mining conditions.

The product is manufactured in accordance with relevant Chinese mining industry standards and internal technical specifications, ensuring reliable performance in coal mining and bulk material handling environments.

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

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

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

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 conveyor systems.
