Belts
Wedge Belts (SPZ, SPA, SPB, SPC)
Wedge belts have a narrower, deeper profile than classical belts, so a drive can use fewer belts and smaller pulleys for the same power. Fit them only in pulleys grooved for the SP profile, and do not mix them with classical belts.
- SPZ, SPA, SPB and SPC profiles
- Higher power per belt than classical sections
- Requires SP-grooved pulleys

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.
