RS PRO Drive Belt Wedge Belt SPA Rubber Polyester 1800 mm Outside Length, 1755 mm Inside Length, 136-8371

The RS PRO 136-8371 is a wrapped high-performance wedge drive belt specifically designed for mechanical power transmission applications that demand reliability under challenging operating conditions. This model features a SPA profile, offering an outside length of 1800 mm and an inside length of 1755 mm, both precision-manufactured for optimal fit and consistent performance. The construction deploys heavy-duty wear-resistant rubber in combination with specially treated low-stretch polyester tension cords, enabling the belt to transfer high loads efficiently and to resist flex fatigue and shock.

The belt is engineered for industrial users seeking durability, high load capacity, and resistance to environmental contaminants like oil, heat, ozone, and dirt. Thanks to its consistent length per ISO standards, it is particularly suitable for synchronizing power transmission in multi-belt installation, making it a trusted choice in large machinery, HVAC drives, mixers, pumps, and material-handling systems where reliability is critical. Its operating temperature range spans from negative 40 to 70 degrees Celsius, making it suitable for a wide variety of climates and environments.

With an abrasion-resistant composition and antistatic properties to ISO 1813, the RS PRO 136-8371 wedge belt ensures safe, dependable operation in workplace environments where static electricity could pose a risk. The deep SPA section profile enables higher horsepower transmission in a compact form factor - ideal for machinery where space constraints are a concern. The robust polyester cords deliver excellent power transfer characteristics while preventing elongation under sustained loads, supporting system efficiency and prolonging belt life.

The RS PRO wedge belt is used across industries including industrial automation, process manufacturing, HVAC, agriculture, and material-handling equipment. The compatibility with ISO 4184 and DIN 7753 standards ensures that this drive belt can readily replace or work alongside other standard-compliant belts. Maintenance is simplified by the durable construction - resisting oil, heat, and environmental wear ensures less frequent replacement and reduced downtime.

The SPA section, with a width of 12.7 mm and height of 10 mm, is a popular size for compact, powerful drives. The rubber is fiber-reinforced and designed to handle high tension, supporting both high start-up torque and sustained load operation. Superior protection against soiling and overhead conditions is built into its fabric-wrapped exterior. As a result, this belt is a dependable selection for power transmission across demanding applications where both efficiency and longevity are required.

RS PRO’s industrial drive belts represent a commitment to quality manufacturing and international compatibility, giving maintenance engineers and equipment builders confidence in belt selection for demanding projects.
