What are Pneumatic Rotary Actuators?

Rack and pinion rotary actuators are essential components in automation and control systems, known for their ability to provide precise rotary motion. They operate on the principle of a rotating gear (the pinion) engaging with a linear toothed bar (the rack). This mechanism ensures accurate and repeatable positioning in various industrial settings.
