| The basic function of a rotary actuator is to convert fluid power into limited rotary motion. | ||

Rotary motion is accomplished by applying fluid pressure to a cylinder piston which drives a (linear) gear rack. The gear rack then drives a pinion gear mated to it, imparting rotary motion to the pinion shaft. The pinion shaft is mounted between two support bearings and is connected to the load either directly, through a coupling or by linkage. Actuator output is measured in lbs.-in., lbs.-ft., or Newton meters and is directly proportional to the net applied pressure (Differential Pressure = delta P). |
