Common tooth profiles and where to use them
When selecting belts and pulleys, match tooth profile and pitch to the application. Typical profiles we stock include HTD for power transmission and GT2 for precise motion control in 3D printers and light robotics. For a broader browse, explore our collections page: Shop by Category.
Specification quick-reference table
| Spec | HTD | GT2 |
|---|---|---|
| Tooth Profile | Curved, high torque | Rounded, high positional accuracy |
| Pitch (examples) | 3M, 5M, 8M | 2 mm |
| Common use | Conveyors, CNC, industrial drives | 3D printers, precision stages |
| Recommended tensioner | Spring/adjuster | Idler or adjustable mount |
Simple selection checklist
- Determine required torque and speed (RPM).
- Match belt pitch to pulley tooth profile and shaft diameter.
- Choose material: neoprene/fibreglass for general use, polyurethane for wear resistance.
- Select tensioning method and compatible accessories (tensioners, idlers, shaft couplers).

Installation notes, calculations and compatibility
Quick calculations help avoid overspec or undersize choices. Use these formulas for initial sizing:
Linear speed (m/min) = pulley circumference (m) × RPM / 60. Pulley circumference = pitch diameter × pi. For torque and power: Power (W) = Torque (Nm) × angular speed (rad/s). These estimates tell you belt load and guide material selection.

A simple two-shaft belt setup:

\__________________________/ (Tensioner/idler above)
Ensure parallel shafts and correct centre distance for your chosen belt length. Small misalignment increases wear and noise.
Troubleshooting common issues
- Slipping: check tension, pulley wear, and correct tooth profile.
- Excessive noise: inspect alignment and change to a softer tooth profile if vibration persists.
- Premature wear: verify material compatibility, contamination, and required service interval for the application.
