Common specifications and when to use them
Choosing the right belt profile and pulley pitch is critical for performance. Typical profiles we stock:
| Profile | Pitch (mm) | Use cases |
|---|---|---|
| GT2 | 2.0 | 3D printers, small CNC, precise micro-stepping |
| HTD (5M/8M) | 5.0 / 8.0 | Medium-duty conveyors, robotics arms |
| T5 / T10 | 5.0 / 10.0 | Power transmission in automation, high torque |
Quick compatibility checks
Match belt pitch to pulley teeth count and belt width. Example formula for linear travel per motor revolution with a pulley:
Linear travel (mm/rev) = Pulley circumference / Motor steps per rev = (pi * D) / steps. For toothed pulleys, use: D = (pitch * teeth) / pi.

Specification callouts, accessory bundles and compatibility guidance
We recommend ordering pulleys and belts as matched sets where possible to avoid mismatches in tooth profile or width. Typical bundles we offer include belt + driver pulley + idler pulley + tensioner bracket - ideal for students building motion stages or engineers prototyping drives. For belt tension and life, select belts with reinforcing cords (fibreglass or aramid) for lower stretch under load.
Representative spec table
| Part | Key spec | Typical use |
|---|---|---|
| GT2 6mm belt | 2 mm pitch, 6 mm width | 3D printers, light CNC |
| HTD 5M 15mm belt | 5 mm pitch, 15 mm width | Medium torque conveyors, robotics |
| Aluminium 20T pulley | Matched to profile, bore options | Stepper shaft mounting for precise stages |
Troubleshooting common issues
- Skipping or backlash - check pulley tooth profile and belt tension; consider a wider belt or stiffer reinforcement
- Noise - inspect pulley alignment and add proper idlers or dampers
- Premature wear - verify pulley material and edge finishing; remove sharp flanges
