SE Worm Gear Single Axis Small Slew Drive For High Accuracy PV
Tracking System
Small Slew Drive Description
Solar tracker must have smooth, slow and sturdy motion. The tracker
should possess high position accuracy and high degree of
reliability. These requirements can be attained by specially
designed drivers known as slewing drivers.
Accuracy: 0.1 Degree
Available: 3 inch - 12 inch
Horizontal installation
It is advised to mount the slewing drives upside down on the
azimuth axis in solar applications for better protection and add
protection for the elevation axis. For other applications, the
mounting directions shall be based on the evaluation of the
protection level and it shall be better for better protection.
Vertical installation
It is advised to mount the slewing drives referring to attached
drawing upside in solar applications for better protection. For
other applications, the mounting directions shall be based on the
evaluation of the protection level and it shall be better for
better protection.

Features
1. By adopting slewing bearing as its core component, slewing drive
can bear axial force, radial force and tilting moment
simultaneously.
2. Slewing drive is widely applied in modular trailers, all types
of cranes, aerial working platform, solar tracking systems and wind
power systems.
3. Electric and planetary gearboxes can be designed according to
customer's requirement.
4. Slewing drive has the advantage of saving space in facilities,
max load capacity in a compact design, extensive lifespan, reduced
maintenance costs, etc.
