Product Introduction
The motor‑driven directional roller is one of the key transmission components of belt conveyors, categorized into drive rollers and idler rollers, and widely used in various types of belt‑conveying equipment. It performs functions such as power transmission, changing the belt’s running direction, and adjusting its tension. The cylinder is fabricated from thick‑walled steel plates that are bent and welded, with nondestructive testing conducted after welding. The main shaft is made of high‑quality round steel that has undergone heat treatment and is paired with a heavy‑duty bearing support, providing high structural strength, torsional resistance, and shock resistance, suitable for continuous operation under heavy‑load conditions.
Product Features
1. Optional wear-resistant rubber coating
The roller surface can be coated with rubber—either smooth, diamond‑patterned, or zigzag—to increase the friction coefficient with the belt, prevent slippage, cushion material impacts, reduce belt wear, and ensure stable operation in humid and dusty environments.2. High stability for heavy loads, reliable sealing
Equipped with heavy-duty self-aligning roller bearings and housings featuring effective protection against dust and mud, the roller generates less heat during prolonged continuous operation, reducing maintenance requirements and extending service life.3. Customizable specifications
The roller diameter and cylinder length can be customized according to belt width, conveying capacity, and required tension. It features mounting brackets for lifting rings, allowing adaptation to various installation conditions in mines, quarries, and power plants.4. Robust construction, resistant to deformation
After welding, the cylinder undergoes stress-relief treatment, preventing deformation or eccentricity and ensuring stable belt operation while minimizing misalignment.Application Scenarios
It is widely used in belt conveyor systems across industries such as mining, quarrying, metallurgy, cement plants, ports, and power stations. The drive pulley transmits power to move the belt; the idler pulley changes the belt’s direction, adjusts its angle, and regulates its tension.

FAQ
How often should the support roller be replaced?
There is no fixed service life; it depends on the working conditions. In dry environments with little dust, the service life is long; in mines, quarries, and humid environments with heavy dust, wear occurs more rapidly. Regular inspections are recommended, and if jams, abnormal noises, or roller damage are detected, the rollers should be replaced immediately to prevent scratching the conveyor belt.
What are the main types of support rollers?
They can be classified by application: channel-type bearings, parallel bearings, damping bearings, self-aligning bearings, and return bearings; and by material: steel bearings, high-polymer nylon bearings, ceramic bearings, etc.
What is the main use of a conveyor belt?
Conveyor belts are widely used in mining, ports, power plants, the construction materials sector, the chemical industry, metallurgy, grain processing, and other industries, primarily for the continuous transport of bulk materials, boxes, parts, bags, bottled products, and other regular or irregular goods.
How to choose the right conveyor belt?
The selection of the model must take into account the weight of the material to be conveyed, the material’s temperature, the conveying distance, the operating environment (indoor/outdoor, acidic/alkaline, oil‑contaminated), the operating speed, the drum diameter, and other parameters; you may also provide the operating specifications, and we can help you identify the appropriate model.
