WE
WE horizontal slew drive for solar trackers
The tracker workhorse. Sized on wind back-torque rather than module weight, with IP65 sealing and an encoder option for closed-loop tracking.

Structure
What the structure gives you
A tracker drive spends most of its life holding still, and the load that matters is the storm gust that wants to rotate it. The worm ratio is chosen so that the back-torque cannot drive the worm backwards, which is why no brake is needed.
- Holding torque specified against site wind speed
- Breather positioned above the grease line to stop condensation
- UV-stable seals and paint
- Encoder ready for closed-loop tracking
- Cold-climate grease for -40 °C starts
Typical equipment
Single-axis horizontal trackers, fixed-tilt seasonal adjustment, agrivoltaic and floating tracker systems.
Options you can add
- IP66 sealing set for coastal sites
- Absolute encoder
- Cold-climate grease to -40 °C
- Anti-backlash worm start
- Controller-specific connector

Outside diameter, bore, mounting holes, gear module and the load case are enough for a quote. If you are replacing an existing ring, the old part number also works.
