About LINAK
LINAK is a Danish family-owned company (A/S) headquartered in Guderup, southern Denmark, that develops and manufactures electric linear drive technology. The portfolio includes electric linear actuators, lifting columns, dual actuators, control boxes, control panels and digital solutions such as OneConnect™, LCi™ and Desk Control™. The systems are used, among other things, in hospital and care beds, patient lifts, treatment tables, height-adjustable desks, agricultural and construction machinery, industrial automation, marine applications, renewable energies, as well as HVAC and building technology. Products for electromedical devices are certified to EN IEC 60601-1, in cooperation with UL International Demko in Denmark. Production takes place at sites in Denmark, China (Dongguan), the USA, Thailand and Slovakia; a significant share of manufacturing remains in Denmark, supported by automation and robotics. In the 2025 fiscal year, LINAK achieved revenue of €564 million with around 2,500 employees in more than 25 countries and supplies customers in over 100 countries.
