130103000521B Gearbox Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 130103000521B reducer boasts four major advantages: high efficiency, high torque, stable operation, and strong durability. It is widely used in the traveling, slewing, and mixing mechanisms of construction machinery such as excavators, cranes, and loaders, as well as in heavy equipment in metallurgy and mining. It plays a core role in reducing speed, increasing torque, and stabilizing power transmission. Utilizing a precision planetary gear multi-meshing design, it achieves efficient transmission, low energy consumption, and low noise. It effectively converts the high-speed, low-torque power of electric motors or hydraulic motors into the low-speed, high-torque power required by construction machinery, meeting the demands of heavy-load and stable operation. Adopting a modular design, it offers strong interchangeability, convenient installation and maintenance, and can adapt to complex working conditions such as high dust levels, strong vibrations, and heavy loads. It avoids transmission failures caused by gear wear and structural deformation, ensuring continuous and stable equipment operation. Its adaptability and versatility are extremely high.
This product is made of high-quality materials and precision-machined, strictly following GB/T 24919 and JB/T 10813 standards. The gears are made of 20CrMnTi alloy steel, which is carburized, quenched, and precision ground, resulting in high hardness and strong wear resistance. The housing is made of high-strength ductile iron, which is impact-resistant and structurally stable. It is manufactured through multiple processes such as precision forging, CNC machining, and precision grinding, resulting in a dense and defect-free structure, precise gear meshing, high transmission accuracy, and excellent lubrication and heat dissipation performance. It effectively solves the problems of low transmission efficiency, high noise, easy gear wear, and short service life of ordinary speed reducers, reduces equipment maintenance costs, accurately matches the transmission needs of various engineering machinery, and balances transmission efficiency and service life, significantly improving the service life compared to ordinary speed reducers.
