Why Do Tracking Brackets Require Metal Bearing Housings?

Let's Discuss the Advantages of Metal Bearings

In many mechanical and industrial applications, bearings are crucial components. They not only help support heavy loads but also ensure smooth operation of machine parts. Among the many bearing materials, metal bearings stand out due to their unique properties and are the most widely used, especially in high-demand applications like tracking brackets.

Key Advantages of Metal Bearings

High Load Capacity

Tracking brackets are often used in large-scale ground-mounted photovoltaic (PV) power plants, playing a critical role in supporting and adjusting the angle of solar panels. Metal bearings have excellent load-bearing capabilities, effectively dispersing the pressure from the equipment and ensuring stable operation.

Superior Temperature Resistance

In desert regions where ground temperatures can reach 60°C to 70°C (140°F to 158°F), metal bearings maintain stable performance and dimensions under long-term high-temperature conditions without deformation or failure.

Excellent Wear Resistance

Metal bearings can maintain a low friction coefficient over extended periods, reducing wear and improving the efficiency and lifespan of the system. Our GF Bearing is designed for more than 25 years of use.

Temperature Performance Testing

Our rigorous testing demonstrates how metal bearings maintain structural integrity and performance across extreme temperature ranges.
