JSJ009027171 Output gear shaft Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The Sany JSJ009027171 output gear shaft belongs to the core component system of Sany Transmission. Relying on Sany Group’s more than 30 years of equipment manufacturing experience, it strictly follows the original manufacturer’s production standards and is specially designed for the transmission system of construction machinery. It is widely used in Sany’s main models such as excavators, crawler cranes, and pump trucks. It is suitable for a variety of harsh working conditions and effectively solves industry pain points such as transmission jamming and excessive wear. It helps equipment improve operating efficiency and extend service life. It is a core preferred part for maintenance and replacement in the construction machinery aftermarket and is also one of the popular high-quality parts for export.
As the “core hub” of the transmission system of engineering machinery, this output gear shaft is meticulously crafted in terms of material selection and processing. It is made of high-strength alloy steel and undergoes strict heat treatment processes such as carburizing and quenching. The depth of the carburized layer on the surface is controlled at 0.8mm~1.2mm, the depth of the surface hardened layer reaches 1.7mm~4.0mm, and the surface hardness is as high as HRC55 or above. The core hardness is maintained at HV350~420. This ensures that the gear surface has excellent wear resistance and contact fatigue resistance, while also ensuring that the shaft core has sufficient toughness and strength. It effectively avoids cracks and fractures caused by impact loads or overloads, making it suitable for long-term use in high-intensity operating scenarios such as mining and infrastructure construction.
