Industrial Lineshaft Driven Roller Conveyors

The Technical Advantage of the AstraRoll Lineshaft
Why do facility engineers choose Lineshaft systems over flat belts or chain-driven live rollers (CDLR) for light-to-medium duty? It comes down to Drive Efficiency and Product Safety:

Unmatched Single-Motor Efficiency: A solid steel drive shaft runs the length of the conveyor beneath the rollers. Elastomeric drive belts (polyurethane bands) connect the spinning shaft to each individual roller. Because of this shared power source, you require far fewer drives compared to conventional systems, slashing both your initial capital investment and long-term energy consumption.

Inherent Minimum-Pressure Accumulation: If a carton jams or an operator temporarily stops a box on the assembly line, the elastomeric bands driving those specific rollers act as a natural slip-clutch. The rollers under the box will simply stop spinning—preventing damage to your product and ensuring operator safety—while the rest of the conveyor line continues running normally.

Product Features & Engineering Specs

Massive Drive Distance: A single 0.37Kw (1/2 HP) drive unit has the torque to power up to 36 meters (approx. 118 feet) of continuous conveyor, minimizing complex wiring and electrical drops.

Modular "Plug & Play" Design: Systems are supplied in 3-meter fully assembled lengths as standard, allowing for rapid factory installation, easy reconfiguration, and quick expansion as your operational needs grow.

Complex Configurations Made Easy: By utilizing flexible universal joints on the main drive shaft, power is seamlessly transmitted around 90-degree, 60-degree, and 45-degree curves, ensuring smooth product flow without the need for independent corner motors.

Versatile Roller Options: Choose from precision 25.4mm, 35mm, or 50mm diameter rollers depending on your carton weight, base footprint, and required load capacity.

Ultra-Quiet Operation: The absence of heavy metal drive chains and the use of precision ball bearings and elastomeric bands mean lineshaft conveyors operate at exceptionally low decibel levels, vastly improving the acoustic working environment for warehouse personnel.

Why Choose AstraRoll?

Precision Engineering & Layout Support

• Turnkey Assembly: Because our sections arrive in 3-meter fully assembled lengths—with rollers, drive bands, and shafts pre-installed—your maintenance team can bolt the system together and get your line running in a fraction of the time compared to flat-pack systems.
• Complete System Integration: We don't just supply straight lines. We engineer complete material flow systems, ensuring your straight runs seamlessly, and power your ancillary modules (curves and merges) via high-quality universal joints for a flawlessly synchronized line.

Frequently Asked Questions (FAQ)

Q: Are lineshaft conveyors suitable for heavy wooden pallets?
A: No. Lineshaft conveyors are specifically designed for light-to-medium duty applications (ideal for cardboard cartons, plastic totes, and lightweight assembly parts, typically up to 25-30 kg per meter). For heavy industrial loads like wooden pallets or heavy castings, you should utilize our Chain Driven Live Roller (CDLR) systems.

Q: What happens if an elastomeric drive band (O-ring) breaks?
A: One of the greatest maintenance advantages of a lineshaft system is redundancy. If a single drive band snaps, only that specific roller loses power. The momentum of the product and the surrounding powered rollers will easily push the box over the single dead roller. Replacement bands can be snapped into place in seconds using a specialized tool, without dismantling the entire conveyor.

Q: Can I run this conveyor in reverse?
A: Yes. Lineshaft systems are completely reversible. Simply reversing the polarity of the main drive motor will change the direction of the entire line, making it highly versatile for loading and unloading dock applications.

Q: Can a 90-degree curve really run off the same motor as the straight section?
A: Yes! We connect the drive shaft of the straight section directly to the curved section using a heavy-duty universal joint. The spinning shaft flexes through the curve, powering the corner rollers without needing a separate, expensive power drop.
