Our Linear Actuators are our standard model for medium-high force projects and applications. These actuators provide you with powerful force, precision and the quality you expect only from us.
WHAT IS A LINEAR ACTUATOR
A linear actuator is a piece of equipment which takes the normal motion created by an electric motor, and converts into linear motion through its design. Actuators can move in any direction, provided they have linear space to move, and depending on their design can be moved in either direction. Linear actuators are very simple pieces of equipment – at their most basic, they have a motor, a spindle, and a gear to turn the spindle in the appropriate way. There are of course endless customizations which can make actuators more effective at different tasks.
HOW DOES A LINEAR ACTUATOR WORKS
As has been said, linear actuators function by using a spindle and a gear to turn the regular motion generated by an electric motor into a more specifically linear motion. This is accomplished by attaching the motor to the spindle by means of a special screw called a lead-screw. The direction of the linear motion is determined by which direction the lead-screw turns, be it clockwise or anti-clockwise.
The motor of an actuator is generally set up so that it can only work one way, in much the same way as the spindle can only move one way as determined by the screw, but the wires are easily switched around, allowing for an actuator which moves in the opposite direction. For ease of use, many actuators include a switch which will allow the motor to be reversed.
An actuator is stopped by the use of a small device known as a micro-switch which is generally found on the spindle. When this switch is triggered, a small nut which sits on top of the gear moves to block the linear movement, thereby stopping the motor and bringing the actuator to a stop. It works by having the nut determine the outside limit of the actuator – once this limit is reached, the power to the motor is cut.
LINEAR ELECTRIC ACTUATOR FEATURES
It was mentioned above that quality linear actuators of all kinds have almost endless customising possibilities in terms of modifications, which means that they can be used for almost any type of job possible with minor changes. The general features of linear actuators are as follows:
- 12v actuators are the most common type of actuator, as that type of motor is one which suitable for a very wide range of jobs and situations, but there are others available, including Dc brush, DC brushless, and induction motors. While 12 volt actuators are the most widely used motors, using a different motor can make the actuator more suitable for a specific job, or enable it to be used in a different environment.
- Control box
A gear takes most of the load in any linear actuator and changing it to one which is either bigger or smaller will allow for a greater degree of control over the way in which the equipment moves. Smaller gears will mean a smaller motion, and therefore are good for jobs which require smaller movements and finer control. Larger gears, conversely, will enlarge the field of movement and therefore allow for more movement, though at the expense of slightly less control over that movement. Certain customizations of gears are, like the motors, made for specific tasks, such as using different alloys for higher-intensity work.
A control box is used to control the actuator, hence the name, there a number of different types of control box available without customization, each one of which is more useful or less useful for specific tasks. While most control boxes are separate from the equipment they control, certain types comes with specific add-ons which allow for them to be directly connected.
This is only specific to a few of the more customised electric actuators so far, but a travelling nut is something which is directly connected to the screw, meaning that rather than it being tethered to the motor (and therefore unable to move), it can spin up and down the spindle of the actuator, rather than being confined to one place.

CUSTOMIZED ELECTRIC LINEAR ACTUATORS
It would be next to impossible to have an actuator for every project or application in stock – but we’ve got a solution. Our custom actuators mean that we can provide you with an actuator that’s tailored to your specific project or application.
We can customize actuators to a variety of specifications:
LINEAR ACTUATOR USAGE
Quality Linear actuators can be found in almost every area which requires movable machinery, including robotics, automation in industries, industrial works, and (increasingly) the home.
- The home
- Factory automation
- Industrial machinery
This is something which features mostly small and quiet linear actuators, as we prefer to have the home be somewhere we can retreat to from the hustle and noise of the outside world. The usage in the home is still quite limited, and most turns up in drawer slides, and automated windows, or else in TV and chair lifts.
In this, linear actuators are normally used for endless motions which require strict control. To this end, the linear actuators in factory operations are used mainly in lines which deal with parts of cars and other products which need to be lifted up and down and slid in and out of place absolutely precisely.
This is almost the same idea as the factory automation, with linear actuators being used in machinery which is engaged in heavy, repetitive tasks which require more precision than can normally be extracted from a human. Such equipment would normally include jackhammers, drills, and mining equipment, among other things.
As this is a fairly new field, robotics is something which is still learning where linear actuators can be used. They can be used wherever precise motion is needed, such as in arms which need to move in and out constantly, or up and down at a very precise rate and speed.
ADVANTAGES OF ELECTRIC LINEAR ACTUATORS
There are many reasons why an electric actuator is always the best choice:
- They are quieter than other models;
- Because of the way they are built (with very few moving parts);
- The design is a lot simpler;
- Leading to easy maintenance;
- They allow for a greater degree of control over the process;
- And they are safer, because they incorporate fewer moving parts into their assembly.
