Which component is typically used to convert rotational motion into linear motion in pneumatic systems?

In pneumatic systems, a cylinder is the component that is primarily responsible for converting rotational motion into linear motion. The operation of a pneumatic cylinder hinges on the controlled inflow and outflow of compressed air. When air enters the cylinder, it acts on a piston inside, causing the piston to move linearly along the axis of the cylinder. This linear motion is harnessed to perform various tasks, such as moving loads, applying force, or executing work in automated processes.

It is important to note that while motors and pistons play significant roles in the system, they do not directly fulfill the function of converting rotational to linear motion as effectively as the cylinder does. A motor generates rotational motion, and valves control the flow of air but do not perform the conversion themselves. Hence, the cylinder is the crucial element that achieves the linear action needed in pneumatic applications.
