Belts
Timing (Synchronous) Belts (XL, L, H, XH, XXH)
Timing belts mesh with toothed pulleys so the driven shaft always turns at a fixed ratio to the driver. They need no lubrication and little tension. Trapezoidal profiles such as XL, L and H are common in inch pitch; check the pitch and width before ordering.
- Positive drive, no slip
- No lubrication needed
- Trapezoidal inch-pitch profiles

Pitch is the distance between neighbouring teeth. Belt and pulley must share the same profile and pitch.
Choosing a belt type
| Belt | Positive (no slip) drive | Typical use |
|---|---|---|
| Classical V-belt | No | General industrial drives, fans, pumps, compressors |
| Wedge belt | No | Compact, higher-power drives in less space |
| Cogged V-belt | No | Small pulleys, high speed and shock loads |
| Poly-V belt | No | Compact multi-rib drives, high speed ratios |
| Timing belt | Yes | Indexing, packaging, textile and precision drives |
| Flat belt | No | High-speed, long-span and light-duty drives |
General guidance. Final selection depends on power, speed, centre distance and the driven machine.
