Product Description

Conveyor rollers (also known as rollers or drums) are cylindrical rotating components used in material handling systems. They serve as either driven or idler components to move goods along a conveyor line by rotating on fixed axles, powered by friction, chains, belts, or integrated motors. They are widely used in straight, curved, inclined, and diverting conveyor systems to transport cartons, totes, pallets, and other flat-bottomed items.

Rollers come in powered (motor-driven, chain-driven, belt-driven) and unpowered (gravity or manual) types. Powered rollers are driven by motors or motorized rollers, while unpowered rollers rely on external forces such as gravity or manual pushing. Key components include the roller tube, shaft, bearings, and mounting fixtures.

Applications

Conveyor rollers are widely used across industries for handling unit loads with flat bottoms:

Logistics & Warehousing: Sorting lines, distribution centers, warehouse inbound/outbound systems

E-commerce & Express Delivery: Parcel sorting, package conveying

Manufacturing & Assembly: Production lines, assembly operations, heavy-duty conveying

Food & Beverage: Bottling lines, packaged goods transport (stainless steel rollers for hygiene)

Automotive & Heavy Industry: Component conveying, mining, bulk material handling

Suitable materials: Hard paper cartons, plastic totes, metal bins, pallets, trays, and drums. Soft or irregular items require pallets or totes for support.

FAQ

Q1: What is the difference between powered and unpowered rollers?
Powered rollers are driven by motors or external drive systems, enabling automatic, controlled conveying – ideal for production lines. Unpowered rollers rely on gravity or manual force – simpler, lower cost, suitable for accumulation or short-distance transport.

Q2: What roller materials are available?
Common materials include: Carbon steel (zinc-plated) – economical and versatile; Stainless steel – corrosion-resistant for hygiene-critical applications; Plastic/POM – lightweight and rust-proof; Rubber-coated (PU/PVC) – anti-slip, protects items, reduces noise.

Q3: What drive methods are available for powered rollers?
Options include single chain drive, double chain drive, O-ring belt drive, flat friction belt, multi-wedge belt, synchronous belt, and integrated motorized rollers.

Q4: What is the recommended roller spacing?
A general rule: at least three rollers must support the item at any point during conveying to ensure stability. Recommended spacing = item length / 3 to item length / 4.

Q5: Can rollers be used for curved paths?
Yes. Curved sections are available with tapered rollers to maintain proper tracking. Standard turning inner radii: 300mm, 600mm, 900mm, 1200mm.

Q6: What is the maximum load capacity?
Standard roller conveyors handle up to 60kg per item. Heavy-duty designs can support up to 1000kg or more, depending on roller diameter and configuration.

Q7: Is the roller easy to maintain?
Yes. Regular cleaning of roller surfaces and periodic inspection of bearings, chains/belts, and alignment are recommended. Damaged rollers can be replaced individually without dismantling the entire conveyor.

Q8: What is the maximum conveying speed?
Standard powered rollers typically operate up to 60m/min, with variable speed control via frequency inverter available for specific applications.
