Flange Gear Hub Description
The YNF18405 flange coupling gear hub is a precision-engineered drivetrain component used in excavator and heavy machinery transmission systems. It functions as a coupling interface, transmitting torque between connected shafts while maintaining alignment stability.
Manufactured from high-strength forged steel, the hub is processed through CNC machining to achieve accurate dimensions including ID50-57, OD175.5, and height 75mm. The integrated 48×17 tooth structure ensures stable engagement and efficient torque distribution under load conditions.
A controlled heat treatment process increases surface hardness and fatigue resistance, allowing the component to withstand continuous vibration, impact load, and high torque environments. It is widely applied in construction machinery and industrial power transmission systems requiring reliable coupling performance.
