About V-Belts

V-belts are indispensable components in various industries that use them for power transmission in many types of machinery. Available in numerous kinds, each V-belt has specific features to meet the unique requirements of different applications. MRO offers V-belts with unique characteristics and critical advantages in diverse industrial applications.


Cogged V-belts have cogs or notches on their inside surface, offering significant advantages over conventional flat belts. The unique cogged profile enables increased flexibility, superior heat dissipation, and reduced slippage. The greater flexibility reduces stress on the belt and extends its lifespan, while improved heat dissipation helps prevent overheating and belt failure. The cogs also enable the belt to operate effectively on smaller pulley diameters, making cogged V-belts an ideal choice for compact, high-performance drive systems.


Standard V-belts have a distinctive V-shaped cross-section, which increases the frictional grip. This design allows them to transmit power efficiently between different machine components. Typically, these belts are made of rubber or similar materials, with enhancements for durability and resistance to heat and wear.


Multi-V-ribbed belts have distinct, multiple longitudinal ribs that run along the inner surface of the belt. These ribs correspond to matching grooves on the pulley system, enabling efficient power transmission while minimizing slippage. Their compact design allows them to operate at high speeds, making them an ideal choice for engines with high RPM requirements. Plus, durable materials like rubber and polyester offer high resistance to wear and tear, contributing to their longevity.


Banded V-belts offer several notable advantages, making them a superior choice for many industrial applications. First, their unique construction design reduces vibration and enhances stability, resulting in smoother operation and increased belt life. Second, banded V-belts are better equipped to handle higher load capacities, making them an ideal choice for heavy-duty machinery. Furthermore, they are less susceptible to misalignment issues than traditional belts, reducing maintenance and downtime. Finally, their robust design offers excellent resistance to wear and tear, heat, and oil, contributing to their reliability and efficiency.


Double-V or Hex-V are unique drive belts used primarily in industrial and mechanical applications. The distinguishing feature of these belts is their hexagonal or double V-shaped cross-section. This design ensures a large contact area with the pulley, leading to efficient power transmission and less slippage than conventional V-belts. They are typically used in serpentine drives or multiple pulley drives where both sides of the belt are required to transmit power.
