Renewable energy is a new energy source developed by humans, and bearings play a role in photovoltaic and wind power generation equipment as well as the manufacturing equipment for these devices. For example, our bearings are used in wire saws for cutting solar cell silicon wafers, etching equipment, diffusion furnaces for battery processes, conveyor robots used in various processes, solar tracking devices used in photovoltaic power generation equipment, and main shafts, gear reducers, generators, and rotating components in wind turbines in the field of wind power generation.
