Dayco Poly-V Belt - Premium Automotive Drive Belt Technology
Revolutionary Design Excellence
Dayco developed the first Poly-V BELT® or Multirib belt for the Ford Mustang in the USA in 1979, establishing the industry standard that continues today. This innovative belt features a multiple rib and flat design that provides superior belt-to-pulley contact for significantly less slippage than conventional V-belts.
Advanced Engineering Features
- Superior Grip & Performance: The precision-engineered grooved design provides flexural stress relief for increased flexibility in both normal and backside bending
- Environmental Resistance: Grooves render the belt less susceptible to environmental factors such as dust and splash-induced slip
- Heavy-Duty Construction: Features diesel-grade construction with higher performance capabilities over conventional light-duty belts
- Noise Reduction: Rubber impregnated fabric backing maximizes load carrying capability and minimizes noise often associated with competitor belts
Technical Specifications
- Length: 1555mm (61.2")
- Number of Ribs: 6
- Section: K (PK) - 3.56mm
- Width: 21.36mm
- Material: High-grade EPDM compounds with specially treated cords
Premium Materials & Construction
The belt cord is saturated with a specially formulated treatment that ensures length and belt stability for the life of the belt. Engineered with high-grade EPDM compounds, it’s built to resist heat and harsh under-hood environments experienced in both over-the-road and off-road conditions.
Performance Benefits
- Multiple ribs eliminate the need for matching belts
- Controlled slippage capability in overload situations (such as when A/C compressor engages)
- Specially treated cords resist stretching and ensure length stability
- Heavy-duty construction provides additional integrity without sacrificing flexibility
- Enhanced belt-to-pulley compatibility
