RS PRO 471-691 Drive Belt is a classical A section V belt designed for reliable and efficient power transmission in industrial and commercial equipment. The belt has an outside length of 1040 mm and inside length of 1041 mm, providing precise fitment for standard drive systems and pulleys, especially SPA section applications.
Constructed with high modulus, low stretch polyester cords, this drive belt offers excellent length stability, minimizing the risk of premature elongation or slack during continuous operation. The base rubber is specially compounded to resist cracking while maintaining flexibility, contributing to longer belt life and consistent performance even under demanding conditions.
The rubber and polyethylene terephthalate materials provide durability, resistance to heat, oil, and abrasion, and extended operational reliability. A polychloroprene impregnated poly-cotton jacket further enhances resistance against environmental factors, making the belt suitable for environments with exposure to static and oil, as well as mechanical wear.
The belt is precision-built and does not require matching or coding during installation, simplifying replacement in industrial power transmission systems. It complies with DIN 2215, API 1B, RMA IP 20, ISO 4184, and BS3790 standards for performance and reliability.
Applications include SPA section V belt pulleys used in machinery, HVAC systems, manufacturing, conveyor drives, and other mechanical equipment requiring classical V belt design. The minimum pulley diameter for A section belts is recommended at 80 mm to ensure optimal performance and reduced wear.
The RS PRO 471-691 Drive Belt is manufactured with an adhesion rubber layer, heat-pre-stretched polyester cord, base rubber, and polyester cotton fabric components for robust construction and increased service life. Its anti-static properties and precise dimensions make it ideal for industrial, laboratory, and mechanical power transmission tasks.
