• Functions

1.Torque Amplification: Reduces motor speed by 150–200x while multiplying torque, enabling the upper structure to rotate even with full boom loads.

2.Smooth Operation: Precision-machined gear teeth (with tight backlash control: ≤0.15 mm) minimize vibration and noise during swing, improving operator comfort and control.

3.Load Resistance: Alloy steel gears and cast iron housing withstand radial and axial forces from swing operations, preventing deformation or gear tooth breakage.

4.Integrated Sealing: Equipped with oil seals (e.g., Hyundai 39Q6-12350) and O-rings to retain lubricating oil and block dust, dirt, or water—critical for durability in construction environments.
