In a steam turbine, what role do bearings play?

In a steam turbine, bearings play a critical role in reducing friction and maintaining alignment. This is crucial for the efficient operation of the turbine. Bearings support the rotor and allow it to rotate smoothly by minimizing the contact and friction between moving parts. By reducing friction, bearings help prevent wear and tear on components, leading to increased longevity and efficiency of the machinery.

Additionally, maintaining alignment is essential for the proper function of the turbine, as misalignment can lead to vibrations, which may result in mechanical failure or decreased performance. Hence, the function of bearings goes beyond merely supporting the rotor's weight; they ensure that the rotor operates correctly within its designed specifications, which is vital for the turbine's overall effectiveness and reliability.
