GF Bearing vs. Plain Bearing: Smarter Design for Solar Trackers
Introduction
In solar tracking systems, bearing performance is critical to long-term stability and smooth operation. This article compares two commonly used structures: the GF Bearing Assembly and the traditional Plain Bearing Assembly. Here's why GF Bearings offer a smarter solution.
Features of GF Bearings
High Mechanical Strength
Designed to withstand extreme conditions and heavy loads
Durability
Long-lasting performance with minimal degradation over time
UV & Weather Resistance
Superior resistance to environmental factors
Maintenance-Free
No regular maintenance or lubrication required
±10° Swing Angle
Allows for greater flexibility in tracker movement
Environmental Adaptability
Performs well in diverse climatic conditions
Easy Installation
Simplified installation process reduces labor time
GF Bearings vs. Plain Bearings
| Feature | GF Bearing Assembly | Plain Bearing Assembly |
|---|---|---|
| Swing Angle |
  |
 |
| Installation | Easy and fast; no need for high-precision alignment | Slower; high installation accuracy required |
| Inner Bearing Retention | Ball core securely fixed, not easy to fall out | Ball may fall out under long-term radial stress |
| Tolerance to Structural Deformation | Can accommodate slight tracker deformation or misalignment | Sensitive to misalignment; performance degrades with structure shift |
| Maintenance | Low friction, low noise, maintenance-free | May require periodic inspection or lubrication depending on material |
Why GF Bearings Are Superior
±10° Swing Angle
Allows self-alignment and absorbs structural deformation, accommodating installation inaccuracies and ground settling.
Easy Installation
No need for perfect alignment or ground flatness. Reduces installation time and labor costs significantly.
Secure Inner Core
Ball core is tightly fixed and won't fall out under long-term axial load, ensuring consistent performance.
More Reliable
Better long-term performance with lower failure risk, reducing maintenance costs and downtime.
Conclusion
GF Bearings offer a smarter, more robust solution for solar tracker systems by combining flexibility, easy installation, and long-term reliability. For developers and EPC contractors seeking lower maintenance and better performance, the GF Bearing is the clear choice over traditional plain bearing designs.
