K Series Serpentine Belts

K Series Serpentine Belts – High-Performance Multi-Rib Belts for Automotive and Industrial Applications

K Series serpentine belts, also known as K-section Poly-V belts, are engineered for high-speed, high-torque power transmission in compact drive systems. Featuring a multi-ribbed profile with a rib pitch of 3.56 mm, these belts provide exceptional flexibility, quiet operation, and superior grip across multiple pulley contact points. K Series belts are widely used in automotive serpentine systems, as well as in industrial equipment where consistent and efficient performance is crucial.

Specifications of K Series Serpentine Belts

• Rib Pitch: 3.56 mm (0.140 inches)

• Belt Height: Approx. 4.5 mm

• Top Width: Varies based on number of ribs (e.g., 6 ribs = 21.36 mm)

• Construction Materials: High-strength EPDM or neoprene rubber with tensile cords made from polyester or aramid

• Effective Length Range: Typically from 700 mm to over 2500 mm

• Standards: Conforms to SAE J1459 and ISO 9982 specifications

• Pulley Diameter: Minimum recommended diameter is 50 mm

• Performance: Oil, heat, and abrasion resistant, anti-static, engineered for long service life

Each belt is labeled by rib count and effective length (e.g., 6PK1060 = 6 ribs, 1060 mm effective length).
