VE Series Slew Drives: A Vertical Mounting Solution for Space-Constrained Applications
What Is a VE Series Slew Drive?
The VE Series Slew Drive—short for “Vertical Enclosed”—is a fully enclosed worm gear slewing unit engineered specifically for vertical axis mounting. With a compact profile, high torque density, and weather-resistant casing, the VE series is ideal for solar trackers, vertical booms, robotic arms, and directional antennas that require upright rotation without sacrificing reliability.
What sets VE series apart from standard slew drives is its optimized vertical mounting configuration. This means the housing, seals, and internal geometry are reinforced to manage gravity-affected loads and maintain performance over long-term vertical operation.
Key Features of VE Series Slew Drives
Vertical Axis Compatibility
VE drives are purpose-built for installation where the rotational plane is parallel to the ground. This makes them ideal for vertical tilting solar systems, signboard pivots, and telescoping structures.
Fully Sealed Enclosure
With IP65 or higher ingress protection, VE drives feature:
Aluminum or alloy steel housings
Reinforced shaft sealing
Anti-rust coatings and internal grease channels
This ensures reliability in dusty, humid, or corrosive outdoor environments.
Self-Locking Worm Gear System
The worm drive mechanism provides mechanical self-locking, meaning the load can be held in position without external braking—critical for safety and energy efficiency.
Motor Integration Options
VE drives are compatible with:
DC brushed/brushless motors
AC gearmotors
Planetary reducers or servos
They support flexible mounting configurations for OEMs across industries.
Typical Use Cases
| Application | Role of VE Series Drive |
| Vertical Solar Trackers | Tilt adjustment for concentrated PV systems |
| Signage & Billboards | Rotation and wind deflection mechanisms |
| Military Radar Systems | Directional scanning and stabilization |
| Mobile Robot Platforms | Sensor mast rotation, vertical articulation |
| Weather Stations | Anemometer and antenna control |
