High Stoque Small Slew Ring Bearing Geared Drive For Dual Axis
Heliostat And Parabolic
Description
Our SDE series slewing drive mainly used for PV, STP, CSP solar
tracking systems, this model is dual axis for horizonal and
elevation directions. It can be used for 10 square meters of solar
panels.
We are committed to researching, developing and applying high
quality, precision slewing drives, we provides reliable horizonal
single axis, dual-axis slewing bearings and slewing drives for
solar tracking systems, CSP,CPV solar trackings etc. Our
professional and high-quality products will be also applied well as
a steady solution on aerial working platform, truck crane, timber
grab, drilling rig, spray equipment, hydraulic module
vehicle,automated assembly lines, wind yaw systems,etc.
Advantage
1. Strong overturning moment based on slewing ring
2. Adopt enveloping worm drive
3. Drive larger load for using multi tooth contact
4. Self-locking function

Applications
The most common applications of slewing ring bearings or slewing
drives are dual-axis solar trackers and single axis solar trackers,
such as heliostats, parabolic, fresnel and concentrated
photovoltaics (CPV), satellite or radar dishes, flat or oblique
single axis solar trackers etc. Other applications include
automotive lifts , robotic arm positioners , and stage equipment.
