■Solar Tracker Split Bearings
GSQB is a split bearing specially developed for solar trackers. It has the characteristics of high load capacity, simple installation, self-lubricating and maintenance-free, and high UV resistance. In order to simplify on-site assembly and improve assembly efficiency, the internal ball and the external bearing housing with a split design; To further extend the service life of the bearing and reduce operating noise, a metal friction pad is added between the bearing ball and the base to optimize frictional performance.
■Bearing material design
The inner ball is made of corrosion-resistant, UV-aging resistant and friction-optimized composite material DURAPLAS® MN527, the bearing housing is made of high-strength and UV-aging resistant composite material DURAPLAS® M163, The metal clamp and the friction pad are made of high-strength galvanized steel.
