A linear actuator is a device or machine that converts rotational motion into linear motion and linear movement (in a straight line). This can be done through electric AC and DC motors, as we do at LINAK, or the movement could be powered by hydraulics and pneumatics.
However, electric linear actuators are a preferred option when precise and clean movement is needed. They are used for all types of applications where tilting, lifting, pulling or pushing with force is needed.
Electric linear actuators are used in everything from private homes, the offices where we work, all areas of a hospitals, in production in factories, to farming equipment, and many other places. LINAK electric actuators create adjustment in both
Electric linear actuators can also replace hydraulic and pneumatic solutions in industrial and rugged environments – for example those found in agriculture, construction, and in industrial automation equipment.
A common type of linear actuator is an electric linear actuator. It is made up of three main components: spindle, motor and gears. The motor can be AC or DC depending on the power needs and other influencing factors.
Once a signal is sent by the operator, which can be through a control as simple as a button, the motor converts the electric energy into mechanical energy, rotating the gears connected to the spindle. This rotates the spindle and causes the spindle nut and piston rod to travel outwards or inwards depending on the signal to the actuator.
As a rule of thumb, a high thread count and smaller spindle pitch will cause slow movement but a much higher load capacity. On the other hand, a low thread count, and higher spindle pitch, will favour fast movement of lower loads.

LINAK lifting Columns are hi-tech electrical devices able to convert rotational motion in low voltage DC motors into linear push/pull movement. Lifting columns are designed to deliver elegant height adjustment of modern office desks, a wide variety of workstations, couches and tables in hospitals and general healthcare and many other places.
Electric linear actuators increase efficiency and give users precision movement through a variety of control options and accessories. Control options for electric linear actuators include handsets, footswitches, desk controls, computer software, mobile apps and much more.
With no need for hoses, oils, or valves, electric linear actuators require no maintenance and create a safe environment for users. High-quality electric actuators are also put through a
making it easy for anyone to add precision movement where they need it. Being electric enables the addition of smart features like CAN bus (LINAK offers CAN SAE J1939 and CANopen for actuator controls).
