ACTUATORS

Actuator: Actuator is a device that produces motion (displacement).

ACTUATOR TYPE :

ROTARY ACTUATOR: The rotary actuator is a device use to alternate the rotated positionof an object. Just like the human wrist the actuator enables the rotation of an object,except that rotary actuators are available in a wide variety of models with different -Sizes, Torques, Rotation angles. The energy for the rotation is delivered by pneumatic

pressure. The rotary actuator converts the air pressure from a linear motion to a rotatingmotion.

LINEAR ACTUATOR: Electric actuators with an output rod that provides linear motion viaa motor driven ball or ACME screw assembly. The actuator's load is attached to the endof screw, or rod, and is often unsupported.

Electric actuators whose load is attached to a fully supportedcarriage. Rod less linear actuators provides linear motion via a motor driven ball screw,acme screw, or belt drive assembly.ELECTRICAL ACTUATOR: Electrical actuators use a motor to drive a combination of

gears that generate the desired torque or thrust level.Based on Operating Media Actuator Classified asPNEUMATIC ACTUATOR & HYDRAULIC ACTUATOR : Hydraulic actuators and pneumaticactuators use pressurized fluid such as air or hydraulic oil to produce Linear or Rotarymotion in mechanical components.

Though hydraulic and pneumatic power shares many characteristics incommon, there are some key differences. For example, because hydraulic fluid is muchless compressible than a gas, Hydraulic power is preferred over pneumatic when precise

position control is required. On the other hand, pneumatic power has an edge inapplications where the presence of hydraulic oil could cause problems (e.g. in food

processing machines). Pneumatic systems are also typically less expensive to build thanhydraulic.

ACTUATOR ACTION: SINGLE ACTING/DOUBLE ACTING:

SINGLE ACTING cylinders would extend by pneumatic or hydraulic pressure on the ram,and retract by spring force or gravity.

DOUBLE ACTING cylinders operate by fluid pressure in both directions: in other words,there is a pressure connection on both sides of the ram to force it one way or the other within the cylinder, depending on the valve setting. These actuators are therefore capableof a power stroke in both directions. Sometimes the piston is even fixed and the cylinder moves back and forth around it.In the world of double acting cylinders, you can find single rod types and double rodtypes.The most common type of pneumatic (or hydraulic) actuators is a cylinder.

SINGLE ROD CYLINDERS have a rod leading off the piston on one side, and are smoothon the other. The difference in area (and therefore action) between the rod end and the

smooth end of a single rod cylinder's ram will of course cause a slight difference in actioneach direction, but this is usually small and therefore usually ignored.DOUBLE ROD TYPES have a rod coming off both ends of the piston. This may be

perhaps so that the piston can do work in both directions, or it may just be to equalize theareas on both sides so that the force and speed of the actuator will be perfectly the samein both directions.

Sometimes, however, the system may require that the force and speed are NOT equal both directions. In this case you would need to install a 'differential' piston. The unevencylinder areas will create a slow powerful work stroke in one direction, and a fast retractstroke back.
