U18C Manual Linear Actuator for Solar Tracker Bracket
Manual Angle Adjustment for Outdoor Solar Tracker Structures
The TOMUU U18C is a manual adjustment actuator designed for solar tracker bracket structures that require simple and reliable angle positioning without continuous motor-driven movement.
It can be integrated into different solar tracker bracket designs, with the stroke and installation dimensions selected according to the required adjustment range and mounting structure.
The current configuration provides a rated push and pull load of 6,000N, with maximum static load up to 30,000N when fully retracted.

Designed for Solar Tracker Bracket Adjustment
Solar tracker bracket structures may require periodic angle adjustment to match different project layouts and seasonal operating requirements. The U18C provides a simple manual adjustment method for these structures.
By selecting the appropriate stroke and installation dimensions, the actuator can be matched to different bracket geometries and required adjustment ranges.
Typical Application:
Manual angle adjustment for outdoor solar tracker brackets where positioning is changed periodically rather than continuously.
Stroke & Installation Selection
The required actuator stroke depends on the solar tracker bracket geometry and the target adjustment angle. The minimum installation dimension is based on Stroke + 250mm ±3mm.
Both the front and rear mounting ends use Ø14.2mm holes. Stroke and mounting dimensions should therefore be confirmed together with the tracker structure during product selection.
Solar Tracker Bracket Applications
U18 series manual adjustment actuators can be integrated into solar tracker support and bracket structures for periodic angle adjustment. Actual stroke and installation dimensions are selected according to the mechanical layout of the tracker.
