Linear actuators

LA28 Compact

Strong, silent, and very reliable linear actuator, originally designed for healthcare applications such as wheelchairs, patient lifts, and treatment chairs. Max thrust: 3,500 N.

LA28 Compact

The LA28 Compact is a small and powerful actuator designed for use in system solutions for healthcare equipment or industrial applications .

Ideal applications include wheelchairs, treatment chairs, or patient lifts. Some benefits of the LA28 compact are:

  • Compact design and small installation dimensions
  • Metal back fixture makes the actuator capable of withstanding high static pull force and ensures high safety
  • Quiet operation
  • 3,500 N in push (with strong motor) and 2,000 N in pull
  • Options such as spline and safety nut to ensure safe operation at all times
  • Available with protection class IPX6

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 that fits into tight spaces, such as 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.

Electric linear actuators LA20 inline, LA14 with low built-in dimensions, LA40 with quick release, heavy-duty LA36, and lifting columns LC3 and DL19 IC.

What is an electric 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, 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.

What is an electric linear actuator used for?

Electric linear actuators are used in everything from private homes, the offices where we work, all areas of hospitals, in production in factories, to farming equipment, and many other places. LINAK electric actuators create adjustment in both desks, kitchens, beds, and couches, as well as hospital beds, patient lifts, and surgery tables, among other things, in hospitals and medical centers, for example.

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.

Why use an electric 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 teststhat push the actuators to extremes. This is done to ensure optimal performance at any given time in any situation. They are also 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 enables the addition of 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.
