The High-Speed Poly-V Belt Roller Conveyor (SR500 Series) is one of the most widely used roller conveyor solutions in modern logistics automation systems. This product is specifically designed for flat-bottom box-type cargo, such as cartons, totes, and pallets, ensuring smooth and efficient straight-line conveying. As an upgraded version of traditional roller conveyors, the SR500 Series adopts the Poly-V belt (also known as multi-ribbed belt) as its core transmission method, achieving high-speed, stable, and synchronized roller driving. It perfectly balances high speed, low noise, and heavy-load capacity, making it an ideal choice for modern automated production lines, sorting centers, and similar applications.
LONGWEI, established in 2004, is a professional Chinese manufacturer dedicated to providing customized conveyor systems, modular conveyor units, various rollers, and related components for logistics systems worldwide.

The SR500 Series does not rely on each roller having its own motor (like conventional motorized rollers), nor does it use a single flat belt pressing against the bottom of the rollers (as in traditional friction drives). Instead, one or more continuously circulating Poly-V belts, tensioned to generate sufficient friction, simultaneously drive multiple rollers. The Poly-V belt typically engages with pulleys mounted on the roller end or wraps around specific grooves on the roller body with a certain wrap angle.
Drive Unit: Can be either a geared motor combined with Poly-V belt transmission, or a Poly-V motor drive roller (built-in motor with Poly-V grooves on the outer surface, directly driving the belt) as the direct power source.
Idler Rollers: Non-powered rollers that make up the majority of the conveying surface.
Poly-V Belts: The core transmission elements, with multiple parallel longitudinal V-ribs on the inner surface that perfectly mesh with the pulley grooves, providing a large contact area and high transmission efficiency.
Frame & Bearing Housings: The main supporting structure of the entire system.
Designed specifically for high-speed applications, the SR500 Series achieves a conveying speed of up to 60m/min (higher speeds available upon request), significantly outperforming traditional friction-driven roller conveyors and greatly improving system throughput. The Poly-V belt drive offers high efficiency with minimal energy loss.
The multiple V-ribs of the Poly-V belt engaging with the pulley grooves create a "averaging effect," ensuring very smooth transmission without impact or vibration. Noise levels during high-speed operation are significantly lower than chain drives and some friction drives, improving the working environment.
A single Poly-V belt can drive multiple rollers simultaneously, ensuring consistent surface linear speed across all driven rollers. This feature effectively reduces slipping and skewing of box-type cargo during high-speed conveying.
The large contact area and high friction between the Poly-V belt and pulleys allow for greater torque transmission, enabling the conveyor to handle heavier box-type loads.
The simple structure means the main wear part is the Poly-V belt itself, which can be replaced quickly and conveniently, resulting in low maintenance costs. The belts are made of high-strength, wear-resistant rubber or polyurethane materials, offering a long operational life.
The transmission system is relatively enclosed, minimizing oil contamination, which meets cleanliness requirements for certain industries. With no exposed gears or sprockets, it provides improved operator safety.
The SR500 Series High-Speed Poly-V Belt Roller Conveyor is especially suitable for high-speed, stable conveying of flat-bottom box-type goods. Typical use cases include:
Parcel Sorting Systems: Infeed and main lines in large sorting centers, quickly and smoothly transporting cartons and totes to scanning and sorting areas.
E-commerce Warehouse Conveyor Lines: High-speed inbound/outbound conveying for "goods-to-person" picking workstations, as well as rapid transfer on packaging lines.
Airport Baggage Handling Systems: High-speed conveying of checked suitcases (flat-bottom hard cases) from check-in to sorting areas.
Beverage & Food Industry: Rapid conveying of full cases of beverages and food packaging boxes after high-speed filling lines.
Automated Assembly & Inspection Lines: High-speed transfer of component totes between workstations in industries such as electronics and automotive.
When selecting the appropriate model, please consider the following parameters:
Conveying Speed: Maximum speed and adjustable range (m/min)
Effective Conveying Width: Determined by cargo dimensions
Roller Pitch & Diameter (50mm): Determines support for small items – ensure at least 3 rollers support the smallest box-type cargo
Load Capacity: Maximum load per unit length (kg/m) or maximum weight per piece
Poly-V Belt Type & Quantity: Common types include PH, PJ, PK, etc., and the number of belts used (single, double, or multiple)
Drive Option: Geared motor + Poly-V belt transmission, or Poly-V motorized roller direct drive (the latter offers a more compact structure, ideal for space-constrained installations)
Control Method: Variable frequency speed control, fixed-speed operation, etc.
The High-Speed Poly-V Belt Roller Conveyor (SR500 Series) is a technically mature and high-performance solution for high-speed box-type cargo transportation. By cleverly applying Poly-V belt transmission technology, this product successfully combines high speed, low noise, strong load capacity, and smooth operation. It has become an indispensable component in modern high-efficiency logistics automation systems, particularly suited for applications that require high-speed conveying of regular box-type goods.
