U20K 20,000N Solar Tracker Linear Actuator with Fisheye Front End
20,000N Push & Pull · 24V DC · Ø20mm Spherical Rod Front End
The TOMUU U20K is an electric linear actuator designed for photovoltaic solar tracking brackets. It provides a rated load of 20,000N in both push and pull directions for solar tracker drive applications.
A standard Ø20mm spherical rod front end, also commonly described as a fisheye connection, provides the U20K with a distinct mounting configuration for connection with the tracker structure.
The standard configuration operates on 24V DC with a 7.0A rated current. Maximum static load reaches 65,000N, depending on stroke.

*Maximum static load varies according to stroke. Final configuration should be confirmed according to stroke, installation dimensions and tracker structure.
Fisheye / Spherical Rod Front End
The U20K uses a Ø20mm spherical rod front end as its standard front-end configuration. This connection is also commonly described as a fisheye connection and is used to connect the actuator with the solar tracker structure.
For project selection, the front-end connection should be evaluated together with the actuator mounting position, stroke and tracker installation geometry. Customized front-end and installation configurations are available according to project requirements.
20,000N Push & Pull Configuration
The U20K provides a 20,000N rated load in both push and pull directions. The standard parameter configuration also specifies an extreme load of 35,000N in both directions and a maximum static load of up to 65,000N depending on stroke.
For solar tracker projects, load should be evaluated together with stroke, installation dimensions, mounting geometry and the mechanical requirements of the tracker structure rather than selected as an independent parameter.
Load & Speed Configuration
| Parameter | Specification |
|---|---|
| Voltage | 24V DC |
| Rated Load | 20,000N Push & Pull |
| Extreme Load | 35,000N Push & Pull |
| Rated Speed | 1.3mm/s |
| Rated Current | 7.0A |
The rated speed for the 20,000N configuration is 1.3mm/s. The specified 1.6mm/s ±10% value is the no-load speed.
Installation & Configuration
The U20K follows an overall actuator length of Stroke + 375mm with a minimum installation dimension of 150mm.
The standard front end is a Ø20mm spherical rod. Feedback is supplied without a feedback device as standard, while a Hall sensor is available as an option. Cable, connector, front-end and installation configurations can be selected according to project requirements.
57GW+ Solar Project Experience
By the end of 2025, TOMUU linear actuators had been applied in more than 57GW of solar projects worldwide, supporting solar tracking systems across different project scales and installation structures.
For U20K applications, actuator selection should be confirmed according to the required load, stroke, mounting geometry, installation dimensions and feedback requirements of the tracker structure.
Project Applications
TOMUU heavy-duty linear actuators are used in solar tracking projects for reliable movement and positioning of tracker structures under long-term outdoor operation.
