Hydraulic actuators convert hydraulic energy into mechanical motion and come in two types: linear actuators, which produce linear motion, and rotary actuators, which produce rotational motion. Linear actuators include single acting cylinders, double acting cylinders, and double rod cylinders. Rotary actuators include rotary vane actuators and rack and pinion actuators, which can be single or double cylinder designs.
