Poly V belts give mainly drive solution, but sometimes also are used for transportation. Materials used for Poly V belt manufacturing are of polibutadiene group of materials.
Our main supplier of Poly-V belts is HUTCHINSON® company.
Our Poly V belts have H, J L profiles. Profiles M and K are also available but per special request. Additionally we offer Poly V pulleys, that are not a standard group of products and therefore need to be discussed with our specialists.
Poly V belts cover a wide range of application and are ideal where you have high torque drives and small pulley diameters. They can be used on smooth pulleys due to avoiding the belt to jump off pulley.
The application of overlays allows to use the belt as a drive and transportation element.
Poly V belt structure enables to use those belts for shafts of lower precision. Poly V belts are resistant to elongation, oil and temperatures.
Poly V belts are used for drive and conveyor elements for heavy industry machines like:
- press machines
- grinding machines
- wood processing machines
- conveyor belt drives
- roller conveyor drives
