- Poly-V belts (7Mb)
- Poly-V Pulleys (0,8Mb)
Poly-V belts have triangular section longitudinal ribs. Thanks to the reduced thickness, these belts are very flexible and can be wind up on very small diameters. Poly-V belts can achieve higher peripheral speed than V-belts.
Belt characteristics
- Standard profiles: H – J – K – L – M
- Static Conductive (ISO 1813)
- Temperature: -20/+80 °C
- Tensile member: Polyester
- Compound: Chloroprene
- Available belts with Aramid tensile members for heavy applications
Benefits
- Compact dimensions
- High Flexibility
- High peripheral speed
- High efficiency
- Low noise
- Possibility of using flat pulleys reducing the cost of the system
SIT Poly-V pulleys for mounting taper bushing are designed and manufactured with extreme accurancy to ensure optimal lifetime and performance of the transmission systems. The pulleys are manufactured in accordance with ISO 1940.

Poly-V CONVEYXONIC® belt drives
Cinghie Poly-V Conveyxonic (0,07Mb)
Poly-V Conveyxonic® is an elastic belt that can be installed on a fixed center distance. Thanks to its 97% efficiency and no need for lubrication, these belts are a valid and cheaper alternative to chains. With this type of belt is possible to put in motion up to 50 rolls with one motor. Depending on the profile shape (J, K) they can handle loads from 300Kg up to 2 tons. These elastic belts are fully compatible with all POLY-V pulleys.
