LINAK Company Review: Electric linear actuators, lifting columns and coordinated control systems
LINAK is a Danish family-owned manufacturer of electric linear actuator systems, lifting columns and associated controls. Its products address industrial and off-highway mechanisms, care equipment and ergonomic furniture, with different variants and system requirements across those applications.
Engineering verdict
LINAK is a strong candidate to evaluate when a design needs controlled electric push-pull motion with an established actuator and control-system ecosystem. Its advantage is the system approach around the actuator. Selection still requires an exact force, speed, stroke, duty and feedback configuration; a familiar actuator housing does not establish suitability for another application.

Company history and current scope
LINAK traces its roots to a Danish blacksmith business in 1907, identifies an early electric actuator milestone in 1979 and dates adoption of the LINAK name to 1984. These are distinct milestones rather than competing dates for one unchanged modern product business. The company describes family ownership and an international organization. This review focuses on actuator technology and application support rather than relying on a current executive name or an unverified headcount figure.
Actuators, columns and the surrounding system
Linear actuators convert motor rotation into controlled extension and retraction, while lifting columns combine movement with a structural arrangement intended for a defined lifting task. LINAK also supplies control boxes, user controls and selected integrated-controller configurations. Catalogue entries such as LA12, LA31 and LA36 belong to different application contexts. An industrial actuator, a care-equipment actuator and a furniture lifting system should not be treated as interchangeable solely because each produces linear motion.
Force, speed and duty belong together
For an actuator, maximum force and maximum speed may describe different configurations or load conditions. Specify the force-versus-speed requirement over the chosen stroke, including acceleration, dwell and repetition. Check push and pull ratings, orientation and ambient temperature. Duty-cycle restrictions can be decisive in repetitive automation: a mechanism that performs one successful move may still exceed its thermal limit when the same cycle runs continuously on a production line.
Mechanical guidance and installation
The actuator’s permissible axial force does not imply unlimited side-load capacity. Define the mounting pivots, guides and alignment so the mechanism does not impose unintended bending on the rod or housing. Check extended length, retracted length and service clearance in the real assembly. For a lifting column, the load center and moment requirements are as important as the vertical load. Validate the complete structure rather than transferring a component rating directly to the finished machine.
Feedback, networks and synchronization
Specify whether the application needs simple end-to-end travel, position feedback or controlled coordinated motion. Available feedback signals and network interfaces depend on the selected product code and electronics. Multiple actuators moving a common load require an appropriate synchronization and fault-response strategy; separate units do not remain aligned merely because their nominal speeds match. Preserve control-box compatibility, cables and validated parameters when documenting the production configuration.
Environmental and application boundaries
Industrial, outdoor, medical-care and furniture environments impose different cleaning, ingress, noise and service requirements. An IP rating belongs to a defined product condition and does not automatically cover the installed machine’s connectors, cables or cleaning process. Self-locking behavior or a holding-load specification is also not a universal safety safeguard. Patient-support and gravity-loaded equipment require a system-specific assessment of normal operation, overload, loss of power and foreseeable faults.
Buying decision and lifecycle support
Compare a LINAK system with a pneumatic cylinder, hydraulic arrangement or other electric actuator at the actual cycle and installation conditions. Include the energy supply, controls, fittings, noise, maintenance and downtime implications without assuming one technology always wins. Ask for a complete bill of materials, model-specific documentation, replacement compatibility and lifecycle information. A coordinated actuator system can simplify procurement, but its value depends on correct sizing and preserving the qualified controls and mounting arrangement.

Frequently asked questions
What does LINAK manufacture?
It manufactures electric linear actuators, lifting columns and associated control systems for several markets, including industrial equipment, care applications and ergonomic furniture.
Was LINAK founded in 1907 or 1984?
The company traces its business roots to 1907 and says the LINAK name was adopted in 1984. These describe different historical milestones.
Can an actuator deliver maximum force and speed simultaneously?
That depends on its configuration and load curve. Do not combine separate maximum values without documentation for the exact selected actuator.
Does an actuator replace a linear guide?
Not automatically. Its permitted axial load and side-load limits must be respected. External guidance and alignment may be needed to prevent bending loads.
Do two identical actuators remain synchronized?
Not inherently. Coordinated lifting requires a compatible control strategy and a defined response to mismatch, overload or loss of feedback.
Is every LINAK actuator suitable for washdown or medical use?
No. Check the exact variant, connectors, installation and applicable documentation. A market application or family-level IP statement is not a blanket approval.
Does self-locking eliminate the need for a holding assessment?
No. Load direction, wear, overload and power-loss behavior must be evaluated for the complete mechanism and its intended use.
When should LINAK be shortlisted?
It is relevant where an OEM needs electric linear movement with compatible controls and application support, and can define the complete mechanical duty and system acceptance criteria.
