Motor Drive Roller (MDR) is a highly integrated conveying unit that incorporates core components such as the motor, gear reducer, transmission mechanism, and sensors inside the roller body, forming a self-powered integral roller. Unlike traditional rollers that rely on external motors connected via belts or chains, the MDR features a compact structure, easy installation, and space-saving design. When paired with an intelligent controller, it enables precise start-stop, speed regulation, and directional control, making it easy to integrate into automated production lines or smart logistics systems. It serves as an efficient solution for achieving intelligent and modular conveying equipment.
Gravity roller (or non-powered conveyor roller) is a type of conveyor system component that moves flat-bottom goods or materials using the force of gravity or manual pushing. Engineered for conveyor systems requiring zero external power source. These rollers are commonly used in material handling applications where simplicity, cost-efficiency, and low maintenance are priorities.
Driven roller is a fundamental component in systems ranging from simple material handling to complex, automated distribution and sorting centers. It is powered by gear motors via belt or chain transmission systems, ensuring accurate speed control and reliable transportation for industrial automation systems.
Accumulation roller is specially arranged to meet the requirements of goods accumulation. The difference to a driven roller is the connection type between the driving head and the roller itself. The ordinary driven roller is a fixed connection; the accumulation roller is a movable connection. Accumulation transportation is also called piled transportation. It has not only the function of common drive transportation, but also the feature that goods stop and pile up on the conveyor line in the condition of the driving element still operating, while the operating resistance is not obviously increased.
Tapered roller is a conical-shaped conveyor roller with varying diameters at each end, specifically designed for curved sections of conveyor systems. It effectively guides products smoothly around corners, preventing items from skewing, jamming, or falling off during turning. Depending on their structure, they can be classified into welded steel plate type and taper sleeve type, and, based on the driving method, into non-powered type and powered type.
Drum motor roller is a kind of oil-cooled motor drive roller, special for the belt conveyor. Unlike traditional gear-motor-driven conveyors, the drum motor drive roller integrates all parts into a single unit as the conveyor's power drive. It can replace the widely used motor-reducer type external drive device to form a belt conveyor, which can transport bulk materials such as coal, ore, sand, cement, flour, etc., and can also transport packaged items such as sacks and equipment.
Longwei Automation provides a complete range of high‑strength, high‑quality belt conveyor pulleys and rollers, manufactured with precision machining and advanced welding technology. Our standardized, serialized product line offers reliable solutions for every part of the conveyor system. Driving Pulley: BCP‑D series. Used as the main driving component in under‑belt conveyor systems, delivering power through a rotating shaft. Head/Tail Pulley: Designed for installation at conveyor ends, available in different drive types and structural configurations. Bend / Snub / Take‑up Pulley: BCP‑R fixed‑shaft pulley or R1200 series roller. These pulleys help correct belt tracking, adjust tension, and increase wrap angles. Selection should account for both belt tension and lateral forces. Carrying Idler: R1200 series conveyor roller (anti‑static) Supports the belt, simplifies structure, and reduces friction during operation.
Brake rollers (or speed controllers) are used in gravity flow racks to ensure safe and steady movement of pallets or cases. They prevent excessive acceleration, protect both operators and goods, and automatically adjust to different loads. With constant braking force, they require no maintenance or external power. Through ongoing design improvements based on client feedback and real-world applications, we now offer both internal and external types of brake rollers in a full range of models—light (10–100 kg), medium(200-500 kg), and heavy (1000–1500 kg)—to meet diverse needs.
Founded in 2004, Longwei is a specialized Chinese manufacturer dedicated to providing customized conveyor systems, modular conveyor units, various rollers, and components for logistics systems.
