Trina Tracker, a tracker manufacturer and business unit of Trina Solar Co, has released the white paper "Trina Tracker Spherical Bearing: Unique three-dimensional long-lasting patented component". The document proves the advantages of the spherical bearing’s unique geometric design through rigorous testing and long-term outdoor reliability.
The white paper describes the advantages of spherical bearings over conventional cylindrical bearings after performing numerous tests in real installations.
More than 6 GW of assembly
Trina Tracker, always at the forefront of solar industry innovation and technology, designed and implemented a spherical geometry bearing, adding significant value to the plants. Its three-dimensional articulation improves terrain adaptability and eliminates risks of misalignment and additional forces that create extra friction. Additionally, the assembly of spherical bearings reduces installation time and costs, and it does not require any maintenance during the operation phase of the installation.

According to the white paper, the spherical bearing has proven reliable over more than ten years and accounts for more than 6 GW of assembly.
Increasing return of investments and lower BOS cost
An example of its long-term efficiency is the Zuera project, an 11 MW plant installed in Zaragoza (Spain), where the first spherical bearings were deployed. Since the interconnection of this PV plant in 2008, no cases of bearing failure have been reported.
