SE21 Solar Tracker Slew Drive High Torque and Stability with Hourglass Worm Technology
SE21 Solar Tracker 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.
SE single-axis slewing drives are assured for a 30-year field life
of precise 3D positioning. SE horizontal single axis slewing 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.

Applications
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.The azimuth & elevation combined and enclosed designing can improve the tracking precision and power generation efficiency.
