Collection: K Section Poly V
K Section Poly V Belt
The K Section Poly V-Belt is designed for heavy duty performance in industrial and commercial applications. With a 3.56mm rib pitch, this belt delivers exceptional power transmission and a quieter, smoother operation across multi ribbed pulleys. Ideal for HVAC systems, compressors, large conveyors, and power tools, K section belts reduce slippage and increase drive efficiency.
Crafted from high strength synthetic rubber and reinforced with durable tensile cords, these belts maintain flexibility under load while resisting wear, heat, and oil. Precision molded ribs ensure consistent grip and alignment, even at high RPMs.
Compatible with major brands and available in multiple lengths and rib counts. Cross reference options make it easy to replace worn OEM belts without guessing.
