In utility-scale solar tracker systems, bearings are more than just components—they are the backbone of structural reliability and long-term performance. While some solutions rely on plastic bearings for lower upfront costs, aluminum bearings are increasingly becoming the industry’s preferred option. Here’s why:

✅ Built to Last

Aluminum alloy bearings offer superior mechanical strength, ensuring stable support for PV modules under dynamic wind and snow loads. Their rigidity and durability help reduce deformation and prolong system life.

☀️ Reliable in Harsh Conditions

Plastic bearings tend to degrade under prolonged exposure to UV radiation and high temperatures, leading to cracking or warping. Aluminum bearings maintain their structural integrity and performance even in desert heat, coastal humidity, and other extreme environments.

🛡 Corrosion-Resistant and Low-Maintenance

Surface-treated aluminum bearings provide excellent resistance to corrosion, reducing the risk of rust and wear over time. This translates into lower maintenance needs and improved system uptime.

🎯 Engineered for Precision

Aluminum allows for high-precision machining, which results in better fitment, reduced backlash, and more accurate tracking—critical factors for maximizing solar energy yield.

⚠️ The Real Cost of Plastic

Though plastic bearings may appear cost-effective initially, they often bring hidden costs:

• Deformation due to thermal expansion

• Lower load capacity

• Shorter service life

• Increased maintenance and replacement

These issues can ultimately compromise system performance and increase total lifecycle cost.
