J Series Serpentine Belts

J Series Serpentine Belts – Compact, High-Efficiency Power Transmission Solutions

J Series serpentine belts, also known as J section Poly-V belts or micro-V belts, are precision-engineered for high-speed, compact drive systems. These belts are widely used across industrial, automotive, and commercial equipment due to their slim profile, exceptional flexibility, and consistent power transmission performance. With a multi-ribbed design that combines the benefits of flat and V-belts, J Series belts offer optimal traction, reduced slippage, and low-noise operation.

Specifications of J Series Serpentine Belts

J Series belts adhere to the ISO 9982 and RMA standards, ensuring compatibility across global applications.

• Rib Pitch: 2.34 mm (0.092 inches)

• Height: Approx. 3.5 mm

• Width: Determined by the number of ribs (e.g., 4 ribs = 9.36 mm, 6 ribs = 14.04 mm)

• Effective Lengths: Typically range from 250 mm to 3000 mm

• Material: EPDM or neoprene rubber with polyester or aramid tensile cords

• Minimum Pulley Diameter: 18 mm
