Shafts are cylindrical mechanical components designed to transmit rotational motion and power between different machine parts. Constructed from durable materials like steel, aluminum, or titanium, they feature precise dimensions and surface finishes to ensure smooth operation and minimal friction. Shafts come in various shapes and sizes, including straight, stepped, and splined, to suit specific applications. They play a crucial role in machinery such as engines, pumps, conveyors, and gearboxes, transferring torque from a power source to driven components. Shafts are integral to the functionality of numerous industries, including automotive, aerospace, manufacturing, and robotics, facilitating the efficient operation of mechanical systems.
