FGE7 Slewing Drive for Precision Rotary Applications
FGE7 Slewing Drive is a compact rotary transmission solution designed for equipment requiring controlled rotation, high torque output, and reliable positioning.
The FGE7 Slewing Drive is a compact rotary transmission solution designed for equipment requiring controlled rotation, high torque output, and reliable positioning. With an enclosed housing and effective sealing structure, it helps protect internal components from dust and water ingress while reducing routine maintenance requirements. The drive is suitable for applications where stable 360° rotation, compact installation, and dependable load handling are essential.
Built for demanding rotary equipment, the FGE/FGA series is available across a 3 to 25 inch range in mass production, with multiple precision levels available to accommodate different application requirements. Installation dimensions and input interfaces can also be customized, providing greater flexibility for equipment manufacturers and integrators.
High Torque Performance in a Compact Design
The FGE7 Slewing Drive combines a high-strength gear transmission with a compact housing to deliver substantial torque within a relatively small installation footprint. Its performance is designed to support equipment exposed to both rotational loads and tilting moments, making it suitable for demanding positioning and lifting applications.
The drive provides an output torque of up to 1500 N·m, with a tilting moment torque of 13,500 N·m and holding torque of 10,600 N·m. It can also accommodate an axial load of up to 135 kN and a radial load of up to 53 kN, providing a balanced solution for equipment requiring stable rotary movement under load.
Hourglass Worm Gear for Improved Contact
A key feature of the FGE7 Slewing Drive is its hourglass worm gear design. Compared with conventional worm configurations, the hourglass profile provides a larger contact area between the worm and gear, helping distribute transmission forces more effectively.
Greater gear contact can contribute to smoother torque transfer, reduced localized loading, and longer operating life when the drive is correctly selected and maintained. This design is particularly valuable for applications that require frequent rotation, precise positioning, or sustained torque transmission.
Self Locking for Controlled Positioning
The FGE/FGA series incorporates a self-locking gearset that can help maintain the output position when the drive is not actively rotating. This feature is beneficial for equipment where unwanted movement could affect positioning accuracy or operational safety.
For positioning platforms, solar tracking equipment, aerial working platforms, and welding equipment, controlled holding performance can reduce the need for additional mechanical locking arrangements. Actual self-locking performance depends on operating conditions, installation orientation, load characteristics, and the complete drive configuration.
Continuous 360 Degree Rotation
The FGE7 Slewing Drive supports continuous 360° clockwise and counterclockwise rotation, allowing equipment designers to achieve flexible rotary movement without limiting the operating direction.
This capability makes the drive suitable for rotary platforms, tracking mechanisms, positioning equipment, and other machinery that requires repeated angular movement. Its compact transmission arrangement also simplifies integration where installation space is limited.
Multiple Precision Levels and Custom Options
Different rotary applications have different accuracy and positioning requirements. The FGE/FGA series therefore provides multiple precision levels, allowing customers to select or customize the drive according to their equipment requirements.
Backlash can be controlled to ≤0.2° for the specified configuration, supporting applications where stable positioning is important. Metric and British options are available, while installation dimensions and input interfaces can be customized to simplify integration with different motors, mounting structures, and mechanical assemblies.
Enclosed Housing and Sealing Protection
The enclosed housing of the FGE7 Slewing Drive helps protect the internal transmission components from external contaminants. Shaft sealing and lip seal arrangements provide an additional barrier against dust and water entering the drive during operation.
This enclosed configuration is especially useful for equipment working outdoors or in environments where airborne dust, moisture, and changing weather conditions can increase maintenance demands. By limiting contamination inside the transmission, the design helps support more consistent operation and longer service intervals.
FGE7 Slewing Drive Performance Parameters
| Parameter | Performance |
|---|---|
| Output Torque | 1500 N·m |
| Tilting Moment Torque | 13,500 N·m |
| Holding Torque | 10,600 N·m |
| Axial Load | 135 kN |
| Radial Load | 53 kN |
| Gear Ratio | 73:1 |
| Backlash | ≤0.2° |

These specifications provide a practical reference for preliminary equipment design. Final selection should consider the actual load distribution, rotation speed, duty cycle, mounting arrangement, environmental conditions, and required positioning accuracy.
Applications of FGE7 Slewing Drive
The FGE7 Slewing Drive is suitable for a wide range of rotary equipment where torque transmission and controlled positioning are important. Typical applications include aerial working platforms, high accuracy rotating platforms, solar trackers, and welding positioners.
For solar tracking equipment, continuous rotational capability and positioning control can support accurate movement of tracking structures. In welding positioners, controlled rotation helps maintain the required workpiece orientation during fabrication. High-accuracy rotary platforms can also benefit from the combination of controlled backlash, compact construction, and customizable precision.
FGE and FGA Series for Equipment Integration
The FGE/FGA series provides a broader selection of slewing drive configurations for equipment manufacturers requiring different dimensions and performance levels. With models ranging from 3 to 25 inches, the series can accommodate applications ranging from compact rotary mechanisms to larger industrial equipment.
For OEM projects, customization of installation dimensions and input interfaces can simplify mechanical integration. Customers can also select different precision levels according to the required positioning performance rather than using the same configuration for every application.
