SG-H Spur Gear Slewing Drive: Heavy-Duty Rotation with High Torque and Precision

What Is an SG-H Spur Gear Slewing Drive?

The SG-H Spur Gear Slewing Drive is a high-performance rotational drive unit designed for applications that require precise, powerful motion control. Utilizing a hardened spur gear mechanism instead of a worm gear, this model offers superior transmission efficiency, high output torque, and rapid response.

The “H” in SG-H stands for “Heavy-duty,” reflecting its enhanced structure for tough industrial environments such as construction cranes, mining loaders, solar trackers, and aerial platforms.

Key Advantages of SG-H Spur Gear Slewing Drives

High Transmission Efficiency

Spur gear engagement offers efficiency levels up to 95%, significantly reducing energy loss and enabling faster rotation speeds compared to worm drives.

Robust Load Handling

SG-H units are engineered to support extreme axial, radial, and tilting loads, ideal for lifting mechanisms, turning tables, and robotic joints.

Compact and Modular Design

The gear mechanism is housed within a compact, fully enclosed casing with IP65 sealing. Modular options allow easy motor integration and flexible orientation.

Fast Dynamic Response

Because spur gears avoid self-locking, the SG-H design is favored in systems requiring high-speed adjustments, frequent starts/stops, or bidirectional movement.

Applications Across Industries

IndustryApplication Examples
ConstructionBoom rotation, lifting mechanisms
Solar PowerFast-response tracking for CPV and heliostats
Military EquipmentArtillery platforms, armored vehicle turrets
RoboticsJoint actuation, base rotation units
MiningConveyor swings, drill head positioning
