Low Noise
Arc Tooth Timing Belts

Our low noise arc tooth timing belts address a requirement that pure precision specifications often overlook: audible and structure-borne noise. Using a sound-dampening compound formulation and a tooth-facing material selected specifically for acoustic performance, these belts are engineered for medical devices, office equipment, laboratory instruments, and any installation where a whining or clicking belt drive is simply not acceptable.

Material & Construction

The belt body uses a vibration-dampening polyurethane blend with internal damping characteristics tuned to attenuate the high-frequency components of meshing noise, paired with a soft-touch nylon tooth facing that cushions tooth-to-pulley contact. Tension cords remain fiberglass or steel depending on load class, selected and positioned to avoid introducing their own resonance at typical operating speeds.

Design & Performance

Noise in a timing belt drive originates primarily from air displacement at tooth entry/exit and from structure-borne vibration transmitted through the pulley and mounting frame; this belt line addresses both through tooth-facing material selection and compound damping characteristics, measured and optimized on an anechoic test rig rather than by estimation. The arc-tooth profile itself retains full precision positioning characteristics, so noise reduction does not come at the cost of accuracy.

Manufacturing Excellence

Every compound formulation batch is tested on a calibrated acoustic test bench measuring sound pressure level at standardized speed and load, with results referenced against IEC 60204 machine-noise guidance. Production tolerances on the tooth facing are held tightly, since inconsistent facing thickness is a common hidden source of noise variation between otherwise identical belts.

Customization & Flexibility

Offered in AT5 and AT10 pitch ranges most common in noise-sensitive equipment, with custom widths and reduced-backlash grades available for applications that need both quiet operation and precision positioning simultaneously.

Applications Across Industries

Our low noise arc tooth timing belts are deployed in:

• Medical Devices – patient-facing diagnostic and imaging equipment.
• Office Equipment – printers, scanners, and shredders in shared workspaces.
• Laboratory Instruments – noise-sensitive analytical equipment.
• Home & Light Commercial Automation – quiet-operation consumer-adjacent equipment.
• Broadcast & Recording Studios – camera and lighting rig drive systems.
• Library & Archive Equipment – quiet scanning and retrieval systems.

When the sound of your machine matters as much as its accuracy, a belt engineered for acoustic performance from the compound up makes a measurable, audible difference. Precision that doesn't announce itself.
