Features
- Set Free: tight length tolerance between belts, so multi-belt drives need no matched sets. Replace one belt or the whole set.
- Low elongation and low shrinkage in service, for stable tension and long belt life
- Wrapped construction: a flexible, wear-resistant cover fabric over high-strength, low-stretch polyester cord and a rubber compound that keeps its shape under load
- Suited to compressors, blowers and heavier industrial machinery
How to order
The letter printed on the belt is the section and the number is the nominal length in inches, for example B-130. If the print has worn off, measure the top width of the old belt and compare it with the table below.
| Section | Top width | Height | Typical use |
|---|---|---|---|
| M | 10.0 mm | 5.5 mm | Small machines, light-duty drives |
| A | 12.5 mm | 9.0 mm | Pumps, fans, general machinery |
| B | 16.5 mm | 11.0 mm | Compressors, blowers, heavier industrial drives |
Narrow wedge belts (SPZ, SPA, SPB) look similar but have a different groove profile and cannot replace A or B belts. Not sure which belt you have? WhatsApp us a photo of the old belt with its measurements and we will identify it.
