130301000100A004 Spindle Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 130301000100A004 spindle is an original core transmission component, specially designed for Sany construction machinery equipment (compatible with SY series and other models). As the core hub for power transmission, it can accurately transmit torque, operate stably, and avoid transmission deviation. It is widely used in heavy construction machinery such as excavators and cranes, and is suitable for complex working conditions such as mines and construction sites. It solves pain points such as insufficient precision, rapid wear, and abnormal operating noise, and extends the life of the equipment’s transmission system.
This spindle boasts significant advantages. Precision-machined from high-quality 40Cr alloy steel and subjected to tempering heat treatment, it possesses both ultra-high rigidity and wear resistance. It can withstand high-intensity torque, is not easily deformed or worn, and ensures long-term stable operation. The spindle surface is precision ground to achieve a high degree of smoothness. Combined with precision bearings, it operates smoothly and quietly, offering high transmission accuracy. This effectively reduces power loss and improves equipment operating efficiency. Standard connection interfaces are provided; installation is as simple as tightening bolts, allowing for precise alignment with equipment transmission systems.
The product strictly adheres to original manufacturer standards and ISO international specifications, undergoes rigorous testing, and is resistant to high and low temperatures, aging, and corrosion. It is suitable for extreme operating conditions ranging from -40℃ to +120℃ and can operate stably in harsh environments such as humidity and dust. The combination of high-quality materials and precision manufacturing extends service life, reduces maintenance frequency, balances practicality and economy, and avoids potential equipment failures caused by spindle wear and decreased precision.
