Description

• The function of the drive roller: It 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-bearing capacity. Each type of roller is available in multiple variations, offering different shaft diameters and center spans for selection. The roller surfaces come with options such as smooth steel, diamond-patterned textures, and rubber coverings featuring herringbone patterns.

• The return roller (tail roller), also known as the return idler, is used to guide the conveyor belt back toward the drive roller. These tail rollers may feature built-in bearings or be mounted in external bearing housings, 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. It primarily consists of components such as the drive roller, frame, supports, and drive unit. Conveyor rollers can be classified based on their drive type—into powered, non-powered, and electrically driven models—and according to their layout—encompassing horizontal, inclined, and curved conveying systems.
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, typically treated with hot-dip galvanization to prevent corrosion. The conveyor belt, which is used to transport materials on the roller conveyor, is usually made from materials such as rubber or 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.

Materials:	The tail pulley drum is typically made of steel—either low-carbon steel or stainless steel—to withstand wear caused by continuous use.
Applications:	The tail roller is used in conveyor systems to provide tension for the conveyor belt and ensure proper tracking of the belt. It is typically installed at the tail end of the conveyor, positioned opposite the head roller.
Structure:	The tail roller is cylindrical with a smooth surface, ensuring easy conveyor belt operation. They are typically mounted on a shaft and supported by bearings.
Bearing Type:	The bearings typically used in tail pulley drums are either self-aligning ball bearings or spherical roller bearings, which can handle misalignment and axial loads.
Drum type:	The tail roller comes in various types, including standard, heavy-duty, spiral, and wing-type designs. The type required depends on the specific application and the load capacity of the conveying system.
Shipping packaging:	The tail pulley drum is typically transported in wooden crates or on pallets to prevent damage during transit.
Sample:	Some manufacturers may provide tail pulley roller samples upon request, helping customers evaluate their quality and suitability.
Customization:	The tail pulley roller can be customized according to specific conveyor systems, including dimensions, shaft diameter, and bearing type.
