Helical Gear Enclosed Housing Dual Axis Slew Drive Model SDE21 With AC 380 Motor For Solar Tracker
Enclosed Housing Dual Axis Slew Drive Description
Slew drives use patented hourglass worm technology to give maximum control and movement support. Our worm gears engage 5 to 11 teeth on the pitch line of the ring gear from the hourglass screw, which is higher tooth engagement than standard worms, giving the gearbox greater stability and strength. Learn more about hourglass technology.
The most common slewing drive application for the dual-axis slewing
drivesare dual-axis solar trackers, such as heliostats and
concentrated photovoltaics (CPV), and satellite or radar dishes.
Other applications include automotive lifts, robotic arm
positioners, and stage equipment.
SDE Dual-Axis Positioner Specifications
SDE dual-axis slewing drives are assured for a 30-year field life
of precise 3D positioning. SDE drives create an efficient and
reliable solution in a single drive. We qualify all of our
components and raw materials using standards set by ISO 9001,
CE certifications to maximize field life.
