RS PRO SPZ Wedge Drive Belt Rubber Polyester 1437 mm Outside Length, 1399 mm Inside Length 136-8438

RS PRO 136-8438 SPZ Wedge Drive Belt is a high-performance mechanical power transmission component designed for demanding industrial applications. With an outside length of 1437 mm and inside length of 1399 mm, it features a wedge-shaped SPZ section that ensures efficient and reliable power transmission, especially suitable for compact drive assemblies.

The belt is manufactured from wear-resistant rubber and incorporates specially treated low-stretch polyester cords, which are engineered to provide high flexibility, resistance to flex fatigue, and robust dynamic load capacity. This construction allows the belt to withstand high belt tensions and shock loads, delivering superior longevity and reliability in continuous operation.

RS PRO wedge belts are formulated with a fibre-loaded rubber base, affording consistent length as per ISO standards. The belt resists oil, heat, ozone, and abrasion, and is antistatic as defined by ISO 1813. Its robust design is compliant with DIN 7753 and ISO 4184 standards, supporting quality assurance and compatibility across a range of equipment.

Operating temperature spans from -40°C to +70°C, making it ideal for use in environments subject to temperature fluctuations. The belt height is 8 mm, width is 9.7 mm, and its efficient design allows space-saving installation on industrial machinery.

Common applications include drive systems in manufacturing facilities, mechanical power transmission in conveyors and pulleys, HVAC equipment, and any setting requiring reliable, high horsepower transfer in limited spatial configurations. The abrasion and wear-resistant properties safeguard performance even under harsh conditions.
