U20K Linear Actuator with Grip-Type Mounting for Solar Trackers
Grip-Type Mounting Configuration for Photovoltaic Solar Tracking Structures
The TOMUU U20K is an electric linear actuator developed for photovoltaic solar tracking structures. A key feature of this configuration is its grip-type mounting structure, which provides a dedicated mounting interface for integration with the tracker structure.
For solar tracker projects, actuator selection is not only about load and stroke. The actuator mounting position, installation dimensions and connection with the tracker structure should also be confirmed according to the actual mechanical design.
The U20K combines this mounting configuration with 20,000N push and pull rated load, 24V DC power and IP66 protection for photovoltaic solar tracking applications.

Key Features
Final mounting position, stroke and installation dimensions should be confirmed according to the actual solar tracker structure.

Grip-Type Mounting for PV Tracker Structures
The U20K uses a grip-type mounting configuration for integration with photovoltaic solar tracking structures. This mounting structure provides a defined actuator mounting interface while allowing the final mounting position to be matched to the tracker design.
Different solar tracker structures can have different mounting points, actuator angles and available installation space. For this reason, the U20K mounting configuration should be evaluated together with the required stroke and installation dimensions rather than selected separately.
Please provide the actuator mounting position, required stroke, installation dimensions and tracker structure drawing when available. TOMUU can evaluate the appropriate U20K configuration before production.
U20K Dimensions & Mounting Reference
The U20K has a minimum installation dimension of 150mm, while the overall actuator length is calculated as Stroke + 375mm.
These dimensions should be considered together with the required actuator stroke and the mounting position on the photovoltaic tracker. Final installation dimensions should be confirmed according to the project structure.

The drawing above shows the U20K actuator structure and mounting reference. Final stroke, installation dimensions and mounting configuration should be confirmed according to the tracker design.
Matching the U20K to Your Solar Tracker Structure
Solar tracker structures do not always use the same actuator mounting layout. Before selecting the final U20K configuration, the actuator should be checked against the mechanical structure of the tracker.
If a tracker drawing or mounting layout is available, providing it during actuator selection can help confirm the mounting and dimensional requirements more clearly.
Feedback & Connection Options
The standard U20K configuration is supplied without feedback. For projects requiring actuator movement feedback, a Hall sensor can be selected as an optional configuration.
Cable and connector configurations can also be selected according to project requirements, including tinned leads, connector options and different cable lengths.
Feedback and electrical connection requirements should be confirmed together with the tracker controller and project wiring requirements.
Photovoltaic Solar Tracker Applications
The U20K is designed for photovoltaic solar tracking applications where actuator load, stroke, installation dimensions and mounting structure need to work together as part of the tracker system.
The grip-type mounting configuration gives this U20K version a clear installation-oriented role within the solar tracker actuator range, while the final configuration can be evaluated according to the actual tracker structure and 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.
Load, stroke, installation dimensions, mounting configuration, feedback and connection requirements are evaluated according to the actual solar tracker project.
Why TOMUU for Solar Tracker Actuators
TOMUU has been developing linear actuator solutions for solar tracking applications since 2017. Our solar actuator production and testing process focuses on practical outdoor tracker requirements, including load performance, protection, durability and operating performance.

Production & Manufacturing
TOMUU operates dedicated production capacity for solar actuator products. Manufacturing and assembly are carried out according to the confirmed actuator configuration and project requirements before shipment.
For project orders, key configuration information such as load, stroke, installation dimensions, mounting requirements and electrical connections is confirmed before production.


R&D & Testing
Solar tracker actuators operate outdoors over long service periods, so product evaluation involves more than checking basic movement. TOMUU carries out testing for key areas including load, protection, durability and operating performance according to the actuator configuration and project requirements.




Select the Right U20K Mounting Configuration
For a photovoltaic solar tracker project, please provide the required load, stroke, installation dimensions, actuator mounting position, tracker structure or drawing, feedback requirements and project quantity.
If the mounting structure differs from the standard configuration, please include the relevant mounting dimensions or drawing so that the actuator installation can be evaluated before production.
