SPA Series Narrow Wedge Industrial V Belt

Narrow Your Results By:

SPA Series Narrow Wedge Industrial V Belts are engineered for efficient power transmission in industrial machinery where high torque, speed, and compact design are required. As part of the metric narrow wedge belt family, SPA belts conform to DIN 7753 and ISO 4184 standards, ensuring compatibility with a wide range of European and global power transmission systems.

Specifications of SPA Industrial V Belts

  • Top Width: 13 mm

  • Height: 10 mm

  • Included Angle: 40°

  • Pitch Width: Approximately 11 mm

  • Standard Length Range: 732 mm to 3550 mm (Li)

  • Material: Heat- and oil-resistant rubber with polyester tensile cords

  • Operating Temperature: -30°C to +80°C

  • Design: Solid or cogged construction (optional)

The SPA belt’s narrow profile delivers more power than classical belts of similar top width, making them ideal for high-speed, space-saving drive systems.

Applications of SPA V Belts

SPA Series V belts are widely used in medium-duty to heavy-duty industrial equipment, particularly where space efficiency and performance consistency are essential. Common applications include:

  • Fans and blowers

  • Air compressors

  • Industrial pumps

  • Packaging and conveyor systems

  • Agricultural and forestry machinery

  • Machine tools and textile equipment

Their excellent grip, stability, and longevity make SPA belts ideal for continuous operation in both single and multi-groove drives.

Why Choose SPA Narrow Wedge Belts?

SPA belts offer higher power density, better alignment stability, and reduced maintenance compared to classical V belts. They enable designers and maintenance professionals to reduce pulley sizes and increase energy efficiency—making SPA belts a smart, reliable choice for demanding industrial drive systems.
