Bearings in electric generators are essential for supporting the rotating components, such as the rotor and shaft, while minimizing friction. They ensure smooth and efficient rotation, which is crucial for optimal power generation. Bearings handle both radial and axial loads, allowing the generator to operate reliably under varying loads and speeds. High-quality bearings reduce energy loss, improve performance, and extend the lifespan of the generator by preventing wear and maintaining precise alignment of moving parts.
