The bearings have a thick layer consisting of a fluorpolymeric compound, which is said to have better tribological properties compared with traditional bearings. The new bearings reliably avoid the stick-slip effect that occurs if the static friction is too high. Consequently, the mirrors can follow the sun smoothly and nearly vibration-free. At the same time, the energy consumption caused by tracking is kept low.

Saint-Gobain guarantees a 25-year lifespan without the need for additional maintenance efforts. Solglide bearings are available with different base materials. They range from normal steel with corrosion protection to aluminium and stainless steel layers. In order to meet high environmental requirements, Saint-Gobain does not use heavy metals or other critical materials, such as Chromium VI. Additionally, no lubricants are used, in order to avoid cleaning costs.
