LA40

The LA40 is a low-noise and powerful actuator, available in a 1,500 N, 4,000 N, 6,000 N and 8,000 N version.

It enables LINAK to offer a durable actuator with high speed/high performance and mechanical endstop for first failure safety. This makes it the right choice for the future market. The LA40 versions are rated up to IPX6 Washable DURA™, except for the LA40 PL version which is rated up to IPX6.

The LA40 (8,000 N) is available in three versions:

  • LA40 (Standard)
  • LA40 HP (High Performance)
  • LA40 PL (Patient Lift)

Based on the extensive knowledge and experience from previous actuator families, LINAK has developed new gear and braking principles that improve the efficiency of the LA40. These innovative solutions are covered by several patents.

Equipped with a socket for exchangeable cables, the LA40 has the same flexibility as previous families, and existing minifit cables can be used.

The LA40 family has a very smooth design, expanding its field of application thanks to easy cleaning and mounting flexibility.

The LA40 is designed for a wide range of applications within both the medical and beds market, such as care and hospital beds, couches, and dental chairs. The LA40 can be ordered with an optional spline function (push only) and/or quick release.

LA40 8,000 N range:

  • The standard version runs 8,000 N from 0-50 mm stroke length with a subsequent decreasing load on the rest of the stroke length
  • The High Performance version can perform 8,000 N on full stroke length 
  • The Patient Lift version can perform 8,000 N on full stroke length.

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 favour fast movement of lower loads.

Initialising a single actuator system for comfort beds

How to initialise a single actuator system for comfort beds

  1. Connect to the mains
  2.  Actuators on the bed must be in inner position
  3. Press the "down" button of the actuator on the hand control for approx. five seconds
  4. The actuator now initiates and can drive outwards
  5. Repeat this for each actuator by pressing the matching "down" button on the hand control
  6. The actuator system is now initialised

What are the different types of electric linear actuators?

There are many types and sizes of electric linear actuators. From small and compact that fit into tight spaces, such as 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 customisation 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.

LINAK business areas for electric linear actuators

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 a 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, surgery tables among others in for example hospitals and medical centres.

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 tests that 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.
