LA44
The LA44 is available in powerful 10,000 N and 12,000 N versions, ensuring safe patient handling.
With the actuator LA44, LINAK offers a product which, with its wide range of safety options, low noise level, and outstanding performance, is the right choice for medical applications such as patient lifts ,beds, dental chairs, etc.
- Heavy duty actuator
- Max. thrust: 12,000 N for push application only
- Max. speed: 14 mm/s
- Manual lowering: makes it possible to turn the inner tube down by hand in case of emergency, or if electrical power is not available
- Spline: potential work injuries are prevented by the spline, as the actuator can only push and not pull, in case something touches, e.g., the lifting boom on a patient lift
- High side load capacity for high safety: Side load of up to 1,000 N is possible without breaking or damaging the actuator
- Safety nut: to ensure safe patient handling even when the actuator is no longer new
- Unique and improved brake to ensure no unintended movement

How do linear actuators work?
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 favor fast movement of lower loads.

What are the different types of electric linear actuators?
There are many types and sizes of electric linear actuators. From small and compact to fit in tight spaces, like in wheelchairs, to large and powerful to move heavy items like a wheel loader engine hood. In addition to size and power, there are also many different designs of electric linear actuators.
The original design has a motor housing that is outside of the gear and spindle profile. But when space is limited, an inline actuator is used so that the motor only extends the shape of the profile. For desks and some medical applications, lifting columns are used for an inline motor housing with two and three stage options.
Since the founder and CEO of LINAK, Bent Jensen, made his first electric linear actuator in 1979, the company has continued to develop new actuators and refine the innovative technology behind them to improve movement solutions for several industries.
LINAK designs and manufactures many types of linear actuators and lifting columns with various speeds, stroke lengths, and capacities. From the compact, inline LA20 to the robust LA36, LINAK actuators are built to fit almost any application.
With an almost endless list of customization options to help design an actuator specifically to fit unique applications, the range of LINAK actuators is even greater than the vast product range listed.
What is a linear actuator?
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, or the movement can be powered by hydraulics and pneumatics.
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.

What is a linear actuator used for?
Actuators can be found anywhere, in homes, offices, hospitals, factories, farms, and many other places. Our electric actuators bring movement to the office and home with adjustable options for desks, kitchens, beds, and couches. In hospitals and medical centers, you will find actuators adding movement to hospital beds, patient lifts, surgery tables and more.
For industrial and rugged environments, electric linear actuators can replace hydraulic and pneumatic solutions found in agriculture, construction, and in industrial automation equipment.
Why use a linear actuator?
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 variety of tests that push the actuators to extremes. This is done to ensure optimal performance at any given time in any situation. They also are designed, along with their accessories, to be easily mounted and installed in a variety of applications.
Making it easy for anyone to add precision movement where they need it. Being electric adds opportunities for additional smart features like CAN bus (LINAK offers CAN SAE J1939 and CANopen for actuator controls). Integrated Controller (IC) solutions can provide various position feedback options, virtual limits, soft start and stop, current limitation, and adjustable speed.
