• Function of the drive roller: The drive roller transmits the torque provided by the drive unit to the conveyor belt. Drive rollers are classified into three types—light, medium, and heavy—based on their load-carrying capacity. For each type of roller, multiple shaft diameters and center spans are available for selection. The roller surfaces can be equipped with smooth steel surfaces, diamond-patterned textures, or rubber coverings with herringbone patterns.

• The return roller (tail roller), also known as the return idler, is used to guide the conveyor belt back to the drive roller. These tail rollers may be equipped with built-in bearings or mounted in external bearing housings, and they are typically located at the end of the conveyor frame.

The conveyor roller is a common material-handling device characterized by its simple structure, high reliability, and ease of use and maintenance. A conveyor roller primarily consists of components such as the drive roller, frame, support brackets, and drive unit. From the perspective of drive mechanism, conveyor rollers can be categorized into powered rollers, non-powered rollers, and electric rollers. According to their layout configuration, they can be classified into horizontal conveyors, inclined conveyors, and curved conveyors.
The drive roller is the core component of a roller conveyor, serving to support and drive the operation of the conveyor belt. It consists of a steel tube and bearings, and is typically coated with hot-dip galvanizing to prevent corrosion. The conveyor belt is the component of the roller conveyor used for transporting materials; it is usually made from materials such as rubber and nylon. Depending on the characteristics of the material being conveyed and the length of the conveying distance, different types and specifications of conveyor belts can be selected.
