SPA1107 Premium SPA Section Wedge Belt - 1062mm Inside Length

Wedge belts, also known as narrow V-belts, are a type of power transmission belt designed to offer superior performance compared to classical V-belts. They have a narrower profile and a deeper cross-section, which allows them to handle higher loads and transmit more power while requiring less space. This design enhances their efficiency and makes them suitable for high-stress industrial and automotive applications.


Key Features of Wedge Belts:

Narrower Profile: Wedge belts have a narrower and deeper profile compared to classical V-belts. This shape allows them to fit into smaller pulley grooves, providing better contact and grip.

High Power Transmission: The design of wedge belts enables them to transmit higher power levels efficiently. Their increased surface contact with the pulley grooves reduces slippage and improves torque transmission.

Durable Construction: Made from high-quality rubber compounds and reinforced with strong tension cords, wedge belts offer excellent durability, flexibility, and resistance to stretching. The materials are often resistant to heat, oil, and wear, ensuring long service life even under demanding conditions.

Efficiency: The efficient design of wedge belts reduces energy loss due to slippage, improving overall system efficiency. This makes them an ideal choice for applications requiring high power transmission and reliability.

Standardized Profiles: Wedge belts are available in standardized profiles (SPZ, SPA, SPB, SPC, 3V, 5V, 8V) that ensure compatibility with a wide range of pulleys and machinery. These standards make it easy to find the right belt for specific applications.

Low Maintenance: The durable construction and efficient design of wedge belts result in reduced maintenance requirements, lowering operational costs and minimizing downtime.


Applications of Wedge Belts:

Industrial Machinery: Used in a variety of industrial applications, including pumps, compressors, conveyors, and milling machines, where reliable and efficient power transmission is crucial.

Agricultural Equipment: Commonly found in tractors, combine harvesters, and other farming machinery, providing dependable power transfer under varying loads.

Automotive: Utilized in engines and accessory drives, such as alternators and power steering systems, to provide consistent and reliable power transmission.

HVAC Systems: Employed in heating, ventilation, and air conditioning systems to drive fans, blowers, and compressors efficiently.

Mining and Quarrying: Suitable for heavy-duty equipment used in mining and quarrying operations where durability and high power transmission capabilities are essential.


Advantages of Wedge Belts:

Higher Load Capacity: The narrower, deeper profile of wedge belts allows them to handle higher loads and transmit more power than classical V-belts.

Space Efficiency: Their design requires less space for installation, making them suitable for applications with limited space.

Increased Efficiency: Reduced slippage and better grip on pulleys improve the overall efficiency of the power transmission system.

Durability and Longevity: Constructed from high-quality materials, wedge belts offer excellent resistance to wear, heat, and oil, resulting in a longer service life.

Versatility: Available in a range of standardized profiles, wedge belts are versatile and can be used in various applications across different industries.


Wedge belts are a highly efficient and durable solution for power transmission needs in industrial, agricultural, automotive, and HVAC applications. Their narrower profile, high power transmission capacity, and superior durability make them an ideal choice for demanding environments where reliable performance is essential. By providing better grip, reduced slippage, and increased efficiency, wedge belts contribute to the smooth operation and longevity of mechanical systems, offering a cost-effective and dependable solution for various power transmission requirements.
