• Drive roller function: Transmits torque from the drive device to the conveyor belt. Drive rollers are classified into light, medium, and heavy types according to their load-bearing capacity. Various shaft diameters and center distances are available for the same type of roller. The roller surface has a polished steel surface, diamond pattern, and herringbone pattern rubber covering.
• Return rollers (tail rollers) are also called return rollers and are used to guide the conveyor belt back to the drive roller. These tail rollers may have built-in bearings or be mounted in external bearing housings, usually located at the end of the conveyor frame.
Conveyor rollers are a common material handling device, characterized by their simple structure, high reliability, and ease of use and maintenance. Conveyor rollers mainly consist of drive rollers, frames, supports, and drive units. The structural forms of roller conveyors are divided into powered, unpowered, and electric rollers according to the drive form, and into horizontal, inclined, and turning conveyors according to the layout form.
The drive roller is the core component of the roller conveyor, used to support and drive the conveyor belt. It consists of a steel pipe and bearings, and is usually hot-dip galvanized to prevent corrosion. The conveyor belt is the component of the roller conveyor used to convey materials, usually made of rubber, nylon, etc. Different types and specifications of conveyor belts can be selected according to the characteristics of the material and the conveying distance.

| Material: | Tail rollers are usually made of steel, which can be low carbon steel or stainless steel, to withstand wear and tear from continuous use. |
| Application: | Tail rollers are used in conveyor systems to provide tension for the conveyor belt and ensure correct belt tracking. They are typically installed at the tail end of the conveyor, opposite the head roller. |
| Structure: | Tail rollers are cylindrical with a smooth surface to facilitate conveyor belt operation. They are typically mounted on a shaft and supported by bearings. |
| Bearing Type: | Bearings used in tail rollers are typically self-aligning ball bearings or spherical roller bearings, capable of withstanding misalignment and axial loads. |
| Roller Type: | Tail rollers come in various types, including standard, heavy-duty, spiral, and winged types. The required type depends on the specific application and load capacity of the conveyor system. |
| Transportation and Packaging: | Tail rollers are usually transported in wooden crates or on pallets to prevent damage during transportation. |
| Samples: | Some manufacturers may provide tail roller samples upon request to help customers evaluate their quality and suitability. |
| Customization: | Tail rollers can be customized for specific conveyor systems, including dimensions, shaft diameter, and bearing type. |
