3V Wedge Industrial V-Belts – Compact, Efficient Power Transmission for High-Speed Applications
3V wedge industrial V-belts are engineered for modern power transmission systems that require high efficiency, compact design, and superior torque capacity. With a narrower, wedge-shaped profile, 3V belts deliver more horsepower per inch of width than classical V-belts, enabling the use of smaller pulleys and tighter drive assemblies without compromising performance. This makes them ideal for applications where space savings and high-speed capability are essential.
High-Strength Construction for Demanding Environments
Manufactured from premium neoprene or EPDM rubber, 3V belts offer excellent resistance to heat, oil, abrasion, and environmental wear. Strong polyester or aramid tensile cords provide exceptional dimensional stability and reduced stretch, ensuring long service life under continuous load. The belt’s wedge profile enhances frictional engagement within the pulley groove, minimizing slippage and improving energy transfer efficiency. This results in smoother operation, improved tension control, and reduced vibration in high-speed drives.
For applications requiring even greater flexibility, 3VX cogged belts incorporate precision-molded notches on the inner surface. These cogs reduce bending resistance, increase airflow for better cooling, and allow the belt to operate effectively on smaller-diameter pulleys.
