Cummins engine spare parts V-shaped multi wedge belt C6451315

Built as a high-efficiency power transmission component, this belt features a V-shaped multi-wedge structure (10 wedges) that maximizes contact with pulley grooves. The wedge design increases the friction area by 60% compared to traditional flat belts, enabling it to transmit 15kW of power—sufficient to drive multiple accessories (water pump, alternator, air conditioning compressor) simultaneously. The evenly distributed wedges reduce stress concentration, minimizing slippage even under sudden load changes (e.g., a truck accelerating with full A/C). For the ISX15 engine, this design maintains accessory rotation stability (±20rpm), ensuring consistent cooling and electrical power supply, and reducing fuel consumption by 2% compared to worn or mismatched belts

Engineered to endure continuous tension and bending, the belt uses a premium composite structure. The core layer is made of high-tensile aramid cords (tensile strength 3000MPa), resisting elongation (≤1% after 1000 hours of use) and preventing belt slack. The adhesion layer (chloroprene rubber) bonds the cords to the wedge layer, ensuring structural integrity. The wedge surface is made of hydrogenated nitrile rubber (HNBR) with a Shore hardness of 75±5, enhancing wear resistance. This composite structure enables the belt to withstand 10 million bending cycles (equivalent to 300,000km of operation) without cracking, far exceeding the service life of ordinary rubber belts (80,000km)

Designed to adapt to the high-temperature and oil-contaminated environment of engine compartments, the belt exhibits exceptional resistance. The HNBR wedge layer operates stably at temperatures ranging from -30℃ to 120℃, resisting thermal aging and hardening. It withstands short-term exposure to 150℃ (e.g., during engine overheating) without melting. The belt’s surface is coated with a oil-resistant film that repels engine oil and coolant, with volume swelling ≤3% after 24-hour immersion. The aramid core is inert to chemical degradation, ensuring performance in dusty construction sites or high-humidity marine environments. It passes 500-hour thermal cycle testing (from -30℃ to 120℃) with no performance loss

The multi-wedge belt is optimized for low noise and long-term cost savings. The smooth wedge surface and precise fit with pulleys reduce operating noise to ≤60dB(A)—40% quieter than traditional V-belts, enhancing driver comfort. Its high durability extends service intervals to 150,000km, reducing replacement frequency by 60% compared to aftermarket belts. The belt’s resistance to slippage prevents premature pulley wear, avoiding costly pulley replacement (up to $300 per unit). Installation is simplified by its flexible design and length accuracy—no specialized tools are needed, reducing maintenance time by 30%. Backed by a 1-year/150,000km warranty, it minimizes unplanned downtime for fleet operators and ensures reliable accessory operation
