This document refers to the product “Mining Belt Conveyor Tapered Rubber-Covered Idler Roller (Φ108 / 108 mm)” manufactured by Huaibei Hezhong Mechanical Equipment Co., Ltd..

The tapered rubber-lined idler roller is a key component used in mining belt conveyor systems, designed to support the conveyor belt, improve belt tracking stability, and reduce operational resistance and wear.

The rubber-coated (lagged) surface enhances friction performance between the belt and the roller, helping to prevent belt deviation and extend service life under heavy-duty mining conditions.

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

In international engineering practice, similar conveyor components are widely applied and generally aligned with industrial 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 dimensional and structural requirements

This product is an essential mechanical component in conveyor systems rather than a safety certification item, and is widely used in mining, port handling, metallurgy, and power plant conveyor systems.
