Shaft

A shaft is a long, cylindrical component used in machinery to transmit power or rotary motion between parts. Commonly found in engines, turbines, and gear systems, it acts as a central axis around which various mechanical parts rotate or operate. Shafts can be made from metals like steel or aluminum and are designed to handle forces, torque, and sometimes support bearings. They are essential for transferring energy efficiently within machines, keeping mechanical systems functioning smoothly and reliably.
