Functions

Single-axis movement support – allows the solar module structure to move in one direction according to the tracking system mechanism
Friction reduction – helps reduce resistance between moving structural parts
Structure stabilization – provides support for the moving part of the solar module structure
Mechanical load distribution – helps distribute the load more evenly in the bearing and structure assembly
Protection against wear – wear-resistant construction helps extend the service life of the moving mechanism
Corrosion resistance – aluminium housing is suitable for outdoor use where the product is exposed to moisture and temperature changes
Smoother solar module tracking – helps ensure more even module movement according to the position of the sun

Use

For solar power plant installers: This bearing is relevant when installing or repairing single-axis solar tracking systems. It is used as a moving support element, allowing the module structure to change its position according to the tracking mechanism.

For electricians: Useful when working with solar power plant systems where the mechanical part of the structure is integrated with electrical control, drive or automation. The bearing helps ensure that the tracking system moves smoothly and without excessive mechanical load.

For engineers and designers: When designing solar tracking systems, it is important to select components that match the structure loads, movement range and environmental conditions. This bearing can be used in projects where single-axis module movement with a ±10° tilt angle is required.

For solar power plant maintenance specialists: The bearing can be used as a spare or replacement part during solar tracking system maintenance. Worn or corroded bearings may cause uneven movement, squeaking, structural looseness or increased load on the drive.

For household users: Relevant for smaller solar power systems with a moving structure. However, installation is recommended to be carried out by a specialist, as incorrect bearing selection or installation may affect the operation of the entire tracking system.

FAQ

What is this solar tracking system bearing used for?
This bearing is designed for single-axis solar tracking systems where the solar module structure moves or changes tilt according to the position of the sun.

Is this bearing suitable for all solar module structures?
No. The bearing is suitable only for structures where the dimensions, mounting solution and movement angle match the parameters of this bearing. Compatibility must be checked before ordering.

Is the bearing corrosion resistant?
Yes, the bearing housing is made of aluminium, making it more resistant to corrosion and suitable for outdoor use.

Is this bearing suitable for outdoor use?
Yes, it is designed for solar power plant structures, which are usually installed outdoors. However, it is recommended to evaluate specific environmental conditions: moisture, temperature, dust, loads and maintenance frequency.
