120701080027A Automotive V-belt Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

120701080027A Automotive V-belt is a factory-customized power transmission component for automobiles and construction machinery. It is primarily used for power transmission between engines and auxiliary equipment such as fans, generators, water pumps, and air conditioning compressors. It features high transmission efficiency, wear resistance, tensile strength, high and low temperature resistance, and easy installation. It is suitable for various scenarios such as construction sites and highways. Its trapezoidal cross-section structure can stably transmit power, preventing slippage, breakage, and wear failures. It adapts to the transmission layout of equipment to ensure smooth operation of the power system.
As the core “high-efficiency transmission unit” of automotive and construction machinery power transmission, this product relies on a precise trapezoidal cross-section design and high-quality material ratio to achieve efficient and stable power transmission. It also has transmission, protection and tensile strength functions. The material is corrosion-resistant and durable, with outstanding transmission performance. It is easy to install and maintain, and complies with GB/T 12732-2008 and ISO 2790 industry standards. It is a high-quality original part for repair and replacement and bulk stocking, and is widely used in automotive and construction machinery after-sales service, complete machine matching and parts procurement.

【Core Technical Parameters】

— Product Model: 120701080027A
— Product Type: Automotive V-belt (Original Equipment Manufacturer, Core Component for Power Transmission in Automobiles and Construction Machinery)
— Compatible models: Sany, XCMG, Caterpillar and other construction machinery as well as various passenger cars and commercial vehicles. It is compatible with the engine auxiliary power transmission and replacement of excavators, loaders, cars, trucks and other equipment.
— Material: The main body is made of high-temperature resistant EPDM rubber, the core rope is made of high-strength polyester fiber, and the outer layer is made of wear-resistant polyester canvas. It is made of precision vulcanization process, with a smooth and burr-free surface, high tensile strength, weather resistance and anti-aging, and suitable for high-temperature oil and sludge conditions in engine compartment.
— Operating temperature range: -30°C to +120°C (wide temperature stability, no brittleness at low temperatures and no softening at high temperatures, suitable for various transmission environments in engine compartments).
— Structural Specifications: Trapezoidal cross-section edge structure, fitting the pulley groove, compact structure, good flexibility, sufficient transmission contact area, compatible with the original transmission layout, achieving smooth and efficient power transmission, with no obvious noise.
— Transmission and wear resistance performance: Transmission efficiency ≥98%, tensile strength ≥15MPa, elongation ≤3%, excellent wear resistance, oil and ozone resistance, not easy to slip or break, can stably transmit power, and is suitable for long-term high-load transmission requirements.
— Size: Compatible with original factory pulleys, tolerance level IT7-IT8, belt width, belt thickness, and effective length fully match the original factory standard, no modification required, models cover common specifications such as AV10 and AV13, and can be customized as needed.
— Installation method: Direct kit installation, compatible with original pulleys and tensioning mechanism, easy to install, can be repeatedly disassembled, easy to maintain and replace, and fits tightly after tensioning, not easy to fall off.
— Protective performance: oil-resistant, water-resistant, and oil stain-resistant; salt spray resistant for ≥96 hours; corrosion-resistant, vibration-resistant, wear-resistant, and ozone aging-resistant; suitable for dusty construction sites, high-temperature oil stains in engine compartments, and other working conditions; not prone to aging or cracking.
— Service life: ≥3 years under normal conditions, ≥1.5 years under harsh conditions. Stable transmission performance and wear resistance are 45% higher than ordinary V-belts, reducing power transmission failures and maintenance costs.

Regardless of the application scenario, such as construction sites or highways, this product can achieve efficient power transmission for automotive and construction machinery engine auxiliary equipment. It is wear-resistant, durable, and provides smooth transmission, ensuring the smooth operation of the power system and reducing the equipment failure rate caused by slippage and breakage. It is the preferred original part for automotive V-belt replacement.
