SHAFT

A shaft is a rotating mechanical element used to transmit power and torque between machine parts such as gears, pulleys, and bearings. It is typically cylindrical and can be either solid or hollow, depending on application needs. Shafts are subjected to torsional, bending, and axial loads, requiring precise material and design selection. They are commonly used in motors, gearboxes, turbines, and automotive systems. Proper alignment and support using bearings are essential to ensure smooth and efficient rotation.
