Aluminum vs. Plastic Bearing Housings: Which Performs Better?

Choosing the right bearing housing material is key to optimizing cost, durability, and performance in solar tracker systems. This article compares two common types: aluminum housings and plastic (polymer) housings.
























































Conclusion
Aluminum housings offer superior strength, UV resistance, and thermal performance, making them the better choice for demanding environments and long-term durability. Plastic housings, on the other hand, provide a cost-effective and lightweight solution for less demanding applications.

When selecting a bearing housing, consider not only the upfront cost, but also the long-term performance, installation environment, and structural requirements of your solar tra
cking project.
