Bearings and Their Challenges in Renewable Systems
Renewable systems rely on precise motion; from turbine blades pitching to solar arrays tracking, and hydro turbines spinning. The smooth rotation and consistent efficiency of this equipment are ensured by high-quality bearings. The quality of bearings matters because even a small fault can halt a turbine, which can put a pause to power generation for weeks or months. Therefore, bearing performance is as important as the blades or panels themselves. Key Challenges for Bearings in the Field Bearings are supposed to endure harsh weather conditions and variable loads. The following are some challenges that bearings have to face: Misalignment and Deflection: Heavy blades and flexing shafts can misalign bearings. This demands a type of bearing that can tolerate such mounting errors and has the ability to self-align under load — like spherical-roller bearings. Corrosion and Climate: Wind turbines located in humid conditions face the risk of corrosion and grease contamination due to co...
