Twin Power
Double Sided Timing Belts

Our twin power double sided timing belts are built for a more demanding use case than typical serpentine routing: applications where both belt faces are actively driving substantial loads at the same time, not simply passing through idler contact on one side. This requires a fundamentally more robust construction than a standard double-sided belt, since both tooth rows must independently withstand full working tension without one face's loading compromising the other's performance.

Material & Construction

Both tooth rows are reinforced by independent high-modulus steel cord layers positioned to give each face its own dedicated load path rather than sharing a single central cord layer designed for lighter, single-active-face applications. The body compound is a heavy-duty polyurethane selected for high fatigue resistance under the combined stress of two simultaneously loaded tooth rows.

Design & Performance

In simultaneous dual-drive applications — such as a single belt powering both a main conveyor and an auxiliary counter-shaft at meaningful torque on each face — cord layout and compound fatigue resistance become critical in ways that light-duty serpentine belts, designed for one active face at a time, are not engineered to handle. Twin Power series belts are rated with both faces' load ratings specified independently and validated together under simultaneous dynamometer loading.

Manufacturing Excellence

Production includes simultaneous dual-face load testing on a specialized dynamometer rig capable of applying independent torque to both belt faces at once, replicating true twin-power operating conditions rather than testing each face in isolation. This is a meaningfully different validation standard than typical double-sided belt testing.

Customization & Flexibility

Available in heavy-duty T10 and T20 pitch, sized for genuine simultaneous dual-face loading, with custom width and cord configuration available based on the specific torque split between your two active drive faces.

Applications Across Industries

Our twin power double sided timing belts are deployed in:

• Dual-Output Gearbox Drives – simultaneous power delivery to two output shafts.
• Heavy Conveyor Systems – main and auxiliary conveyor driven from one belt.
• Industrial Mixers – dual-shaft mixing mechanisms.
• Printing Press Dual Drives – simultaneous cylinder and feed roller power.
• Extrusion Line Auxiliary Drives – main screw plus auxiliary puller drives.
• Heavy Agricultural Machinery – dual-implement simultaneous power take-off.

When both sides of the belt are genuinely doing work at the same time, a belt engineered and tested for exactly that condition is the difference between reliable service and premature fatigue failure. Real power, from both sides, at once.
