130802000852A Flange Coupling Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

130802000852A Flange Coupling Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 130802000852A flange coupling is an original equipment manufacturer (OEM) core transmission component, specially designed for Sany construction machinery equipment (compatible with SY series and other models). As the “power bridge” connecting the equipment’s shaft system, it plays a crucial role in transmitting torque and compensating for shaft misalignment. It is widely used in heavy construction machinery such as excavators, cranes, and pavers, and is suitable for complex transmission scenarios such as mines, construction sites, and infrastructure projects. It solves pain points such as unstable transmission, vibration and abnormal noise, and installation deviation, helping equipment to transmit power efficiently, operate stably, and extend the service life of the equipment’s transmission system.
As a core component of shaft transmission in engineering equipment, this flange coupling offers significant advantages. It is integrally machined from high-quality 45# carbon steel and features a polyurethane elastomer buffer structure, combining excellent rigidity and flexible transmission performance. It can stably transmit torque, effectively buffer vibration and impact during equipment operation, reduce shaft wear, and compensate for axial, radial, and angular misalignments. This avoids transmission failures caused by installation deviations, ensuring precise and smooth transmission, noiseless operation, no lubrication required, and convenient maintenance. The flange end face is precisely machined with pre-drilled standard connection holes, allowing for quick connection with motor shafts and reducer shafts, resulting in efficient installation and significantly reduced assembly time.
The product strictly adheres to original manufacturer standards and ISO international specifications, undergoing rigorous torque load capacity, impact resistance, and airtightness testing. It exhibits excellent high and low temperature resistance, aging resistance, and corrosion resistance, making it suitable for extreme operating conditions ranging from -40℃ to +120℃. It can operate stably for extended periods in harsh environments such as humidity and dust. The surface is treated with an electrophoretic anti-rust process, effectively resisting rust, extending service life, reducing the need for frequent maintenance, lowering operating costs, and balancing practicality and economy. It is well-suited for the long-term, high-intensity transmission requirements of heavy equipment.
