⚡ At a Glance
  • Power Transfer: Precise tooth engagement from a 3mm pitch for consistent motion
  • Best for: Maintenance and repairs where accurate timing and low slippage matter
  • Not ideal for: Applications that require adjustable-length or repairable joined belts

Rubber closed-loop construction with a 3mm synchronous pitch for accurate engagement. Available in multiple widths and circumferences to match common pulley setups.


Accurate timing and smooth engagement – thanks to 3mm pitch

A 3mm pitch spaces teeth to match HTD 3M pulleys so teeth mesh precisely without skipping. Regular tooth spacing keeps rotational phases stable across the drive train.

Consistent motion reduces vibration and timing error, important for CNC, printers and robotics. Expect repeatable positioning when pulley selection matches belt pitch.

Secure, maintenance-lite operation – with rubber closed-loop construction

Closed-loop rubber eliminates joins and heat-sealed splices, creating a continuous band that distributes load evenly. The elastic backing helps absorb shock and resists slipping under steady loads.

Fewer failure points mean less frequent replacements and easier long-term upkeep. Suitable for projects where downtime must be minimised.

Flexible fit for many setups – thanks to multiple widths and circumferences

Widths available include 6, 9, 10, 12, 15 and 20 millimetres, while circumferences cover C=366 to C=399 mm in listed increments. A specific example size listed is 3M 384 with 128 teeth.

Choice of width and length makes matching pulley width and centre distance straightforward. Select the exact combination to reduce the need for idler adjustments.

✨ The 4 Key Reasons for GatherTOOL Timing Belt
  1. Closed-loop rubber construction – Ensures no joins and dependable continuous operation under steady load
  2. 3mm pitch tooth profile – Matches standard HTD pulleys for precise timing engagement
  3. Multiple width options – Choose suitable width for torque demands and space constraints
  4. Range of circumferences – Select exact belt length for accurate fit and minimal adjustment
