VE5 Single Axis Solar Tracker Slew Drive, Low Backlash IP66 Worm Gear Drive
Slew Drive Description
The VE5 single axis solar tracker slew drive is a compact and robust rotary drive designed for photovoltaic tracking systems. It combines a slewing ring bearing and worm gear transmission into an integrated housing, providing reliable rotation, high holding torque, and precise positioning for solar tracker applications.
With low backlash, IP66 protection, self-locking capability, and a 0–180° rotation range, the VE5 slew drive is suitable for outdoor solar tracking systems where stable movement and reliable load holding are essential.
The drive can be installed with the motor on either the left or right side, making it easier to adapt to different tracker structures and installation layouts.
VE5 Slew Drive for Single Axis Solar Trackers
Solar tracking systems can generally be divided into flat single-axis, inclined single-axis, and dual-axis configurations. The appropriate slew drive depends on the tracker structure, array size, wind conditions, installation angle, and required tracking accuracy.
The SE and VE series slew drives can be used for various single-axis solar tracking applications, while the SDE series is commonly used for dual-axis solar trackers.
For inclined single-axis tracker applications, the VE series provides a high-torque solution for rotating and holding PV arrays under outdoor operating conditions.
Key Features of VE5 Solar Slew Drive
Low backlash: backlash as low as ≤0.1° for accurate solar tracking.
High holding torque: designed to securely hold the PV array when the drive is stopped.
Self-locking worm gear: helps prevent reverse rotation caused by external loads, reducing the need for an additional mechanical brake in suitable applications.
IP66 protection: suitable for outdoor photovoltaic tracking environments.
0–180° rotation: supports a wide tracking range for single-axis solar trackers.
Flexible motor installation: motor can be mounted on the left or right side.
Compact integrated design: slewing bearing and worm gearbox are integrated into one unit.
Factory-filled grease: supplied ready for installation, reducing commissioning work.
Easy installation: suitable for integration into different solar tracker structures.
Low maintenance: enclosed transmission helps simplify routine maintenance.
Smooth start and stop: provides stable rotational movement for solar tracking.

Applications
VE series slew drives can be used in:
Single-axis solar tracking systems
Inclined single-axis PV trackers
Flat single-axis solar trackers
Utility-scale photovoltaic power plants
Ground-mounted solar tracking systems
Solar thermal tracking equipment
Other outdoor rotary positioning equipment
How to Select a Solar Tracker Slew Drive
Selecting the correct slew drive should not be based only on the weight of the PV modules. The required drive capacity also depends on:
Total PV array area
Total moving weight
Center of gravity and eccentric load
Operating wind speed
Survival wind speed
Tracker configuration
Installation orientation
Required tracking angle
Required positioning accuracy
For a specific solar tracker project, Hangtuo can recommend a suitable slew drive based on the complete mechanical and environmental parameters.
