Rotary actuators are used to provide torque from hydraulic pressure. Examples include locks used in combination with rotary actuators; valve units for converters; and grease for lubricating the operation of line flow channels and sliding parts.

Electric linear actuators meet the sophisticated needs of robotics. Depending on the design, the air pressure forces the piston or the diaphragm to move creating linear or rotary motion. Ideal for: High-speed production applications and situations where low wear and long life are important, Our PTR Series of rack and pinion rotary actuators are one example of this type of actuator. The Direct Drive Motor is a rotary actuator that directly drives a rotary table with a motor without using any speed reducing mechanism such as a belt or reduction gears. The cracking pressure of the meter-in check valves is set high enough to prevent flow into rotary actuator 2 while rotary actuator 1 is rotating, but lower than the pressure that develops once rotary actuator 1 reaches its hard stop. A good definition of an actuator is it is a device that causes motion and it can cause linear motion or rotary motion. The hydraulic actuator includes a cylinder or a fluid motor that works through hydraulic power for mechanical operation. Tritex II rotary motors and gear motors provide a high response and precise control of a rotatable shaft, similar to that found in any electric motor.

They work on exactly the reverse principle, to that of rotary pumps. This does not mean, however, that a gear motor is automatically a rotary actuator. A linear pneumatic actuator can move something in a straight line. If, conversely, we are referring to a device that needs to perform a tugging motion or roll something up, it will be simpler to use a rotary actuator. Linear actuators, on the other hand, move an object along a straight line, generally in back and forth motion. gear (1) and only two moving parts: the central shaft with an integrated bearing and mounting flange (2),
