SH200 Swing Carrier Description
The YNF17896 swing second stage planetary carrier assembly (OEM 19-071) is a critical component in the Sumitomo SH200 excavator swing reduction gearbox system. It is responsible for transmitting and distributing torque within the upper structure swing mechanism, ensuring smooth and stable rotation of the excavator body.
The assembly integrates a 22-tooth carrier structure, 18-tooth planetary gear configuration, and 23-tooth sun gear engagement system. This multi-stage gear coordination ensures balanced load distribution and efficient power transfer during swing operation.
Manufactured from forged alloy steel and processed with precision CNC machining, the carrier provides excellent dimensional accuracy and structural strength. Heat treatment enhances hardness and fatigue resistance, allowing it to perform reliably in continuous heavy-duty excavation environments.
