SG-H Spur Gear Slewing Drive: Heavy-Duty Precision Rotation for Industrial and Energy Applications
What is an SG-H Spur Gear Slewing Drive?
The SG-H Spur Gear Slewing Drive is a high-load, high-precision rotary drive system designed for large-scale industrial automation and renewable energy infrastructure. As the heavy-duty model in LDB’s SG Series, the SG-H integrates robust spur gears and large-diameter slewing bearings into a reinforced housing—delivering smooth, bidirectional rotation even under extreme axial and radial stress.
SG-H drives are particularly suited for systems that require fast rotation, long duty cycles, and high torque without the drag or inefficiency of worm gear systems.
Core Features and Engineering Strengths
High Torque Spur Gear Transmission
The SG-H uses hardened, large-module spur gears to achieve fast, efficient, and reliable rotary motion at scale.
Extreme Load Capacity
Engineered for axial and tilting moment resistance, this model can support loads in excess of 100,000 Nm.
Enhanced Durability for Harsh Environments
IP65-rated steel or cast-iron housing protects internal gears from dust, water, and corrosive exposure. Optional marine-grade finishes available.
Multiple Mounting and Motor Interfaces
Supports direct-drive, planetary, servo, or hydraulic motors with customized flange and shaft adapters.
Precision-Cut Gears with Low Backlash
Backlash as low as 0.05° ensures accurate positioning for critical applications like heliostats, crane bases, and tracking platforms.
Application Scenarios
Utility-Scale Solar Farms: Dual-axis heliostats and CSP (Concentrated Solar Power) mirror fields
Heavy Industrial Robotics: Gantry arms and robotic transport platforms
Offshore and Marine Equipment: Deck cranes, shipboard lifts, and radar alignment
Wind and Hydro Energy Systems: Pitch control and nacelle alignment
Large-Scale Automation: Rotating kilns, material handling turntables, and vertical boring machines
