Linear actuators are used to perform most assembly operations because they do not require complicated motion. This linear actuators serve a multitude of functions and there are various linear actuators website like www.actuatorzone.com that offer information on this. Linear actuators either move side–to-side or up-and-down. There are different types of linear actuators and some factors are taken into consideration when choosing the actuator to use. Some of the factors that are considered include: speed, load, flexibility, accuracy, speed etc.

Some of the uses of linear actuators include:

• During performance of assembly operations, it’s used to snap a stack of parts together or clamp parts in place.
• In a semiautomatic leak testing station it’s used to apply sealing fixtures to an assembly.
• For set of fixtured screw driving spindles or dispensing valve it retracts and extends.
• Used to move pallets and machine-tending robots.

Some of the commonly used linear actuators are:

• Pneumatic Actuators
• Electric Actuators
• Specifying Actuators

Pneumatic Actuators.

This actuators are inexpensive, fast, simple and light weight. They are the standard technology for linear motion. The greatest advantage that pneumatic actuators have over electric actuators is that they produce more force at the end-stroke, this is a high force density. This actuators are very simple and are structured to move only two position.

Electric Actuators

The chef advantage that this actuator has over pneumatic actuators is that it is flexible and easy to control. Unlike pneumatic actuators that can only move two positions, electric actuators can move to a hundred different positions. This actuators allow the user to improve the process for maximum efficiency since one can control both the acceleration and velocity at every position.

Specifying Actuators

This actuators are built in accordance to the specification of the engineer. The engineer is required to provide sufficient information considering all the requirements. He should account for speed, frequency, acceleration and deceleration, direction it would be mounted among other things.
