Used in a variety of distinct ways, furniture actuators are one of the more common uses of linear actuators. Linear actuators can be found in many different appliances and machinery, but one of its most prevalent uses is in the application and creation of furniture. In furniture making, they help automate a number of processes and functions such as eliminating the monotony of everyday tasks, which in turn speeds up production as well as helpin...

Learn everything you need to know about linear actuators. Last time we talked about the basic definition and uses of simple actuators, and introduced the concept of the electric linear actuator (screw-based). To review, a linear actuator is called such because it transforms energy into a linear direction; that is, straight back and forth. This is valuable because most actuators derive their motive force from a rotational source, such as a gea...

An actuator is a motor that transfers energy from whatever is powering it into motion. This explanation may sound simplistic, but at heart, that's what it does. Within that simplicity lies a great deal of utility; the majority of modern devices that involve motion of any kind could not exist without these components. For example: In NASA's Mars Rover: It's full of actuators. The most important power the wheels and the sample collection tool. ...

The first step in determining the size of a linear actuator needed to move a specific load requires the user to calculate translational force. To calculate the translational force, four components must be considered: mass, friction, gravity, and other counter-forces within the system. Each component must be solved for in the equation to yield the appropriately sized actuator. A sample calculation will be provided to help users determine the si...
