RS PRO SPZ Drive Belt 1200mm Outer Length, 1162mm Inner Length, 9.7mm Width, Rubber/Polyester 136-8428

RS PRO 136-8428 SPZ drive belt is a high-quality, high-performance mechanical power transmission belt, engineered for robust and long-lasting use in industrial drive systems. This wedge-type belt features an SPZ profile, with a precisely formed outer length of 1200mm and an inner length of 1162mm, ensuring compatibility with standard industrial pulley systems. Its 9.7mm width and 8mm height deliver reliable, efficient performance for compact spaces where consistent power transfer is essential.

Constructed from heavy-duty wear-resistant rubber and reinforced with low stretch polyester cords, the belt's robust build ensures excellent load capacity, flexibility under tension, and resistance to flex fatigue and shock loads. Its advanced rubber compound base is fiber-loaded, supporting high tension operation and reducing the risk of slippage during demanding tasks. These attributes make it an ideal choice for continuous industrial use and critical drive applications.

Designed to exceed conventional V belt capabilities, this RS PRO wedge belt transmits significantly more power, allowing for higher torque in reduced installation spaces. The belt's deep wedge profile increases its contact area for more effective force transmission, while also providing consistent length as specified by ISO standards for accurate fit and predictable maintenance cycles.

The operating temperature range is -40°C to 70°C, making the belt suitable for diverse environments, from refrigerated facilities to high-temperature mechanical rooms. Additional features include oil, ozone, and heat resistance; abrasion and wear resistance; antistatic properties in line with ISO 1813; and full compliance to DIN 7753 and ISO 4184 standards, ensuring both safety and interoperability in international and quality-critical settings.

For multi-belt drive systems or replacement needs, the model 136-8428 represents the small pack size reference in RS PRO's range.
