Gear type slewing drive features

High Transmission Efficiency: The gear meshing structure offers higher transmission efficiency than worm gears and reduces energy loss.

High Torque Output: Provides strong output torque and load-bearing capacity, suitable for heavy-duty conditions.

Compact Structure: The integrated design of the gear pair and slewing bearing minimizes space and facilitates installation.

Smooth Operation: Precision-machined tooth surfaces ensure smooth meshing and low noise, making it suitable for long-term continuous operation.

Gear type slewing drive advantages

High-precision transmission with minimal positioning error

High torque capacity and strong impact resistance

Multi-scenario adaptability and flexible installation

Low-noise operation and energy saving.
