Product Description

Basic Info

Poly V-Belt

A Poly V-Belt, also known as a multi-rib or serpentine belt, is a power transmission component with multiple parallel V-shaped ribs on its inner surface.

Crafted from durable synthetic rubber reinforced with tensile cords like polyester, it functions as several small V-belts merged together, ensuring efficient power transfer with minimal slippage. The ribbed design provides high flexibility, smooth operation with reduced vibration and noise, and ensures uniform stress distribution for an extended lifespan.

Structure

1. These visible identifiers enable technicians to quickly recognize belt type, size, or manufacturer details, simplifying replacement and maintenance.

2. The synthetic tension members (the yellow, twisted parts) are crucial for strength. The "balanced twist cord" design ensures the belt remains centered on pulleys (neutral tracking), preventing misalignment, reducing wear, and maintaining efficient power transmission.

3. The rubber layer bonds the belt's components (like tension members and outer rubber), preserving structural integrity to prevent layer separation, ensuring consistent performance and longevity. 4. EPDM (Ethylene - Propylene - Diene Monomer) rubber serves as the outer material, offering durability and resistance to heat, weather, and wear. Its "highly engineered" formula ensures quiet operation and long-lasting performance, even in harsh conditions like hot engine bays.

5. Precisely shaped ribs ensure the belt fits snugly in pulley grooves, maximizing contact area. Increased contact enhances power transfer, reduces slippage, and ensures smoother operation.
