14190471 Planetary Axis II Assembly Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 14190471 Planetary Shaft II assembly, relying on professional shaft component manufacturing technology and a strict quality control system, is specially designed for the harsh working conditions of construction machinery. It is widely used in the gearboxes, slewing mechanisms, and traveling mechanisms of major construction machinery such as excavators, crawler cranes, and loaders. It is suitable for various complex scenarios such as mining, infrastructure construction, and building hoisting, effectively solving industry pain points such as planetary shaft deformation, wear, breakage, and loosening. It helps improve the transmission efficiency of equipment and extend the service life of the whole machine. It is a core preferred component for maintenance and replacement in the construction machinery aftermarket, and is also one of the popular high-quality parts for foreign trade export and parts wholesale.
As the “core support” of the planetary gear transmission system, the Planetary Shaft II assembly is meticulously crafted in terms of material selection and processing. It utilizes high-strength alloy structural steel and employs multiple machining processes including precision forging, CNC turning, and grinding, combined with heat treatment processes such as carburizing, quenching, and low-temperature tempering. This effectively enhances the overall strength and dimensional accuracy of the assembly. The shaft surface hardness reaches HRC58-62, while the core exhibits excellent toughness, enabling it to withstand heavy loads, impacts, and other complex operating conditions, preventing shaft bending, wear, or breakage. Simultaneously, the shaft structure design is optimized, with precise machining of positioning steps and mounting slots to ensure assembly accuracy with the planetary gears and planetary carriers. This reduces vibration and wear during operation, improves transmission smoothness, and adapts to high-speed, heavy-load, and other complex operational requirements, allowing for long-term stable operation under harsh conditions.
