A Fenced Type Slewing Drive, also known as Series SE slewing drive, is an enclosed gear mechanism that integrates a slewing bearing with a worm gear.
The housing or “fence” provides protection against dust, water, and harsh environmental conditions.
It is widely used in solar tracking systems, industrial automation, and construction machinery.
Series SE slewing drives are designed with an enclosed structure for higher durability and safety.
They feature compact design, high torque transmission, precise rotation control, and excellent resistance to outdoor conditions.
The protective housing makes them suitable for long-term outdoor installations such as photovoltaic and CSP solar tracking systems.
The fenced design protects internal gears and bearings from dust, rain, and debris.
It ensures longer service life and reduces the risk of mechanical failure.
Other benefits include smooth operation, high load capacity, and compatibility with both horizontal and vertical installations.
Fenced Type Slewing Drives are commonly used in single-axis and dual-axis solar trackers for photovoltaic and CSP systems.
They are also applied in aerial work platforms, cranes, construction machinery, wind power systems, and satellite communication equipment.
Any application requiring stable rotation and outdoor protection benefits from the SE series.
The drive integrates a worm gear mechanism with a slewing ring bearing inside a fully enclosed housing.
The worm transfers torque to the gear, enabling smooth and precise rotational movement.
The enclosed “fence” design prevents contamination and ensures stable operation in harsh environments.
The SE series offers multiple size options to match different torque and load requirements.
Common models include SE3, SE5, SE7, SE9, SE12, SE14, SE17, SE21, and SE25.
Each model provides specific torque ratings, gear ratios, and load capacities to suit diverse applications.
The housing is typically made from high-strength cast steel for durability.
The slewing bearing and worm gear use alloy steel with precision heat treatment for wear resistance.
In some models, seals and gaskets are used to enhance waterproof and dustproof performance.
Load capacity depends on the model size and application.
Smaller SE models can handle light loads for solar trackers, while larger models are suitable for heavy-duty machinery and cranes.
Both axial and radial load capacities are optimized for long-term outdoor use.
The slewing drive must be mounted on a flat and stable surface using high-strength bolts.
Proper alignment is essential to prevent uneven load distribution.
Manufacturers recommend following torque specifications for secure installation and long service life.
Yes, SE series drives are versatile and support both horizontal and vertical mounting orientations.
The choice depends on the application, such as solar tracking systems (horizontal) or machinery rotation (vertical).
SE series slewing drives require periodic lubrication to reduce friction and wear.
Grease is commonly used for both the slewing bearing and worm gear.
Regular maintenance intervals depend on load conditions and environmental exposure.
Routine inspections should check for lubrication levels, bolt tightness, and seal condition.
Re-lubrication should be performed as recommended by the manufacturer.
Avoid overloading and protect the drive from extreme vibrations to extend service life.
Industries such as renewable energy (solar tracking), construction, lifting machinery, mining, and communication benefit greatly.
The enclosed design makes them ideal for applications where reliability and environmental protection are priorities.
Yes, manufacturers can customize gear ratios, torque requirements, sealing protection, and motor compatibility.
Electric and hydraulic motor adapters are available for different drive systems.
Customization ensures optimal performance in unique application environments.
