In solar photovoltaic (PV) systems, bearings are essential components that provide support and enable smooth movement for solar trackers. These components allow solar panels to follow the sun’s path, maximizing energy production. To meet the demands of long-term outdoor use, bearings need to possess excellent load-bearing capacity and be resistant to harsh environmental conditions. GF bearings were developed with these requirements in mind and have become an innovative solution for solar tracking systems.

1. Rigorous Testing to Ensure High Quality

GF bearings undergo multiple strict tests during development and production to ensure they perform reliably under various loads and environmental conditions. Here are some of the main tests and their applications:

• Push-out Test: This test verifies the bearing’s assembly strength. Since solar panels move in multiple directions, the bearing must withstand push-out forces to ensure long-term stability.

• Tensile Test: The tensile test assesses the bearing’s strength when subjected to pulling forces. This ensures the bearing’s stability, preventing deformation or breakage during installation or under mechanical tension.

• Compression Test: The compression test evaluates the bearing’s performance under high compressive loads. GF bearings show excellent results in this test, indicating they can handle the significant compressive force required for solar panel operation.

• Shear Test: This test checks the bearing’s stability against lateral forces, such as those caused by wind. GF bearings demonstrate strong shear resistance, allowing them to maintain stability under such forces.

• Salt Spray Test: The salt spray test is essential for assessing the bearing’s durability in corrosive environments, which is especially crucial for outdoor solar tracking systems. In a 480-hour salt spray test, GF bearings performed exceptionally well, demonstrating high corrosion resistance, making them suitable for various climate conditions.

2. 25-Year Design Life

GF bearings have a design life of 25 years, which ensures stable and durable performance throughout the lifecycle of the solar system. The robust structure and superior material selection not only provide reliable short-term performance but also support solar tracking systems for decades, minimizing replacement and maintenance costs.

3. Innovative Materials and Design

The outstanding performance of GF bearings is due to their innovative materials and design. Constructed from high-performance materials, GF bearings offer excellent corrosion and aging resistance, and they operate with low friction. Compared to traditional bearings, GF bearings deliver consistent performance in extreme conditions, including low temperatures, high temperatures, humidity, and salt spray environments.

4. Extensive Global Application

After years of research and testing, GF bearings have been successfully implemented in solar projects worldwide, receiving high praise from customers. Whether in hot deserts, cold highlands, or humid coastal regions, GF bearings provide reliable support for solar tracking systems in diverse environments.

Conclusion

The impressive performance of GF bearings in photovoltaic applications is the result of strict quality control and rigorous testing. Designed specifically for solar tracking systems, GF bearings not only excel in durability, corrosion resistance, and load-bearing capacity but also leverage innovative materials and design to ensure suitability across various extreme environments. Choosing GF bearings means reliable support for solar tracking systems and ensuring high efficiency over the next 25 years.
