SE14 Gear Ratio 85 / 1 High Accuracy Slew Drive For Single Axis And
Dual Axis Solar Trackers
High Accuracy Slew Drive Description
Slewing worm drive is consisting of worm gear, worm shaft, housing,
bearing, motor and so on. Motor drive the worm shaft, the worm and
envelop worm and gear are engaged to increase the torque, stable
and reliable. Slewing drive is able to sustain more axial load,
radial load and tilting moment. Turntable or frame rotate at
azimuth and elevation driven by slewing drive.

Application
Typical applications include solar trackers, wind turbines,
satellite and radar dishes, truck cranes, man lifts, utility
equipment, hydraulic equipment attachments, oil tool equipment,
tire handlers, digger s, and automotive lifts.
There are more than 10 different sizes, starting from 3' size to
25" inch size, among them are 5", 7", 9" 12", 14", 17", 19" and
21". They are both widely used in solar tracking systems (PV, CPV,
HCPV and heliostat) and regular vehicles, such as man lifts, truck
cranes, as well as modular vehicles.
