V-belts PUR - 3M, 5M, 7M, 11M
V-belts PUR are made of polyurethane with a 60° V-angle. They are specially designed for drives which are required to transmit maximum power as well as to be quiet and vibrationless in operation. The belts are made of highly durable polyurethane and reinforced with special tensile filaments. Their tops are cross-dented.

Application:
These belts are used in drives for special machines that require high revolutions, smooth operation and high accuracy, e.g. machine tools and wood-working machines.
Properties:
- high power transmission at high revolutions (up to 10,000 rev/min)
- outstanding efficiency, long lifespan
- small pulley diameters, compact drives, low vibrations even at high revs
- operation temperatures up to 90°C
Cross-sections:
V-belts PUR are manufactured either as single belts in cross-sections PUR - 3M, 5M, 7M, 11M or as multiple belts in cross-sections 5MS, 7MS and 11MS
Marking:
5M/1150
5M - cross-section; 1150 - La outer length in mm
3/5MS/1150 = 3-ribbed
5M - cross-section; 1150 - La outer length in mm
Cross-sections and length ranges:
| Cross-section | Length Ranges La in mm |
| 3M | 180 - 750 |
| 5M | 280 - 1850 |
| 7M | 500 - 2300 |
| 11M | 710 - 2300 |
| 5MS | 280 - 1320 |
| 7MS | 500 - 2300 |
| 11MS | 710 - 2300 |
