14185667 Planetary Axis II Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 14185667 Planetary Shaft II, relying on professional shaft manufacturing technology and strict quality control, is specially designed for the harsh working conditions of construction machinery. It is widely used in the gearboxes, planetary transmission mechanisms, and travel mechanisms of main models such as excavators, crawler cranes, and loaders. It is suitable for complex scenarios such as mining and infrastructure construction, effectively solving pain points such as shaft deformation, wear, and breakage, helping to improve equipment stability and extend service life. It is the preferred component for aftermarket maintenance, foreign trade export, and parts wholesale.
As the “supporting core” of the planetary transmission system, the planetary shaft II is made of high-strength alloy structural steel and employs precision forging, CNC turning, grinding, and carburizing and quenching processes to improve overall strength and dimensional accuracy. With a surface hardness of HRC58-62 and excellent core toughness, it can withstand heavy loads and impact conditions, preventing shaft bending and breakage. The optimized shaft structure, with precisely machined positioning steps and mounting slots, ensures accurate assembly with the planetary gears and planetary carrier, reducing operational vibration and wear, and enabling stable operation under long-term harsh conditions.
