SE Series Slew Drives: Compact, Enclosed Power for Precision Rotation
What is an SE Series Slew Drive?
The SE Series Slew Drive is a fully enclosed rotary drive system that integrates a worm gear, slewing bearing, and housing into a compact, self-contained unit. Built for durability and precision, the SE (Standard Enclosed) series delivers smooth, controlled rotational movement in applications requiring tight space utilization, environmental protection, and high torque output.
Unlike traditional open-gear slewing mechanisms, the SE series protects internal components from dust, water, and corrosion—making it ideal for outdoor, mobile, and heavy-duty applications.
Key Features and Advantages
Enclosed Housing for Weatherproof Protection
SE series units are IP65-rated, shielding the worm gear and slewing ring from water, dust, and debris. This extends product life in challenging environments.
High Torque in Compact Form
Through the worm gear mechanism, SE drives deliver high torque at low rotational speed—critical for safety and precision in lifting and solar tracking systems.
Self-Locking Capability
The worm gear design provides natural self-locking ability, preventing back-driving and improving safety in vertical installations.
Multiple Mounting Interfaces
Flange and square housing options simplify installation in equipment such as cranes, booms, aerial lifts, and solar trackers.
Motor Compatibility
Compatible with hydraulic, DC, or AC motors. LDB also provides integrated drive-and-motor units on request.
Applications of SE Series Slew Drives
Single-Axis and Dual-Axis Solar Trackers: Offering reliability in daily positioning for PV and CSP systems.
Construction Equipment: In aerial work platforms, telescopic handlers, and concrete pumps.
Military and Defense Systems: For precise targeting and positioning in radar, surveillance, and weapon platforms.
Industrial Automation: Enabling precise movement in assembly lines, welding arms, and logistics.
Marine and Offshore Equipment: Corrosion-resistant models support ship deck cranes and offshore manipulators.
