Product Details

Product Introduction

Our steel double-sprocket conveyor rollers are built to handle the rigorous demands of modern logistics and manufacturing. Unlike standard friction-fit rollers, the steel sprockets are professionally welded directly to the tube body. This creates a unified structure capable of transmitting significantly higher torque, making them the ideal choice for heavy pallet loads and continuous-duty cycles.

Superior Load Capacity and Durability

⚙️

At the heart of each roller is a precision-machined ball bearing secured within a stamped steel housing. This all-metal internal assembly provides a "firm-fit" that resists deformation under pressure. Compared to plastic bearing seats, our steel-housed design offers vastly superior impact resistance and load-bearing performance, ensuring a much longer service life in high-traffic facilities.

Frequently Asked Questions

Q What is the difference between welded sprocket rollers and friction-fit sprocket rollers?

Welded sprocket rollers have the steel sprockets permanently fused to the tube body, creating a unified structure that transmits significantly higher torque. Friction-fit sprockets can slip under heavy loads, making welded variants far more reliable for continuous-duty and heavy pallet applications.

Q What tube diameters and wall thicknesses are available for these double-sprocket conveyor rollers?

We offer a wide range of sizes including Φ50, Φ60, Φ76, Φ80, and Φ89mm tube diameters, with wall thicknesses from 1.5mm up to 3.75mm. Both galvanised steel and stainless steel (SS) tube materials are available across all sizes.

Q Are these rollers suitable for use in cold storage or high-temperature environments?

Yes. These rollers are engineered to maintain peak performance across a wide operating temperature range of -20°C to +80°C, making them suitable for both cold storage warehouses and high-heat industrial processing environments.

Q How are the internal bearings protected from dust and water?

Each roller features a protective plastic end cap fitted over the sprocket, which acts as a secondary seal. Combined with the stamped steel bearing housing, this effectively shields the internal ball bearings from dust, debris, and water splashes in demanding facility environments.

Q Can these rollers be configured with guide flanges for automated conveyor systems?

Yes. Optional guide flanges (guide rims) can be added to maintain strict linear alignment during transport. This is especially important for accurate pallet positioning in automated systems involving robotic arms, sorting equipment, or other precision-driven conveyor applications.

Q Why choose a steel bearing housing over a plastic bearing seat?

Steel bearing housings offer vastly superior impact resistance and load-bearing performance compared to plastic alternatives. The all-metal "firm-fit" assembly resists deformation under high pressure, resulting in a significantly longer service life — particularly critical in high-traffic logistics and manufacturing facilities.
