14185511 Planetary Carrier II Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 14185511 Planetary Carrier II, relying on professional manufacturing technology and strict quality control, is specially designed for the harsh working conditions of heavy engineering machinery. It is widely used in the gearboxes, slewing and traveling mechanisms of main models such as excavators, crawler cranes, and loaders. It is suitable for complex scenarios such as mining, infrastructure, and construction hoisting, effectively solving pain points such as deformation, cracking, and uneven load distribution, helping to improve the transmission efficiency of equipment and extend its service life. It is the preferred component for aftermarket maintenance, foreign trade export, and parts wholesale.
As a core component of the transmission system, this planetary carrier is made of high-quality ZG42CrMoA alloy structural steel, formed by integral forging, and subjected to multiple processes such as carburizing, quenching, low-temperature tempering, and precision grinding to improve overall rigidity, dimensional accuracy, and load-bearing capacity. The surface hardness is HRC58-62, and the core hardness is HV380-450, combining wear resistance and toughness to withstand heavy impacts and prevent deformation and fracture. The optimized double-side plate integral structure, with evenly distributed support columns to enhance heat dissipation and stability, and precisely pre-drilled mounting holes ensure accurate meshing, uniform load distribution, and stable operation under long-term harsh conditions.
