Testing industrial actuators against salt and chemical ingress

At the LINAK® Test Center, electric linear actuators for industrial applications are tested – often to the extreme. Salt and chemicals are some of the harshest compounds to expose your actuator to. See how we test the level of ingress protection against both elements and learn why it matters.

LINAK has one of the most advanced test centers for electric actuators in the world. Every actuator must pass an extensive regime of tests before it leaves the factory. None more so than the ones for industrial and agricultural applications.

Exposed to salt and chemicals
For actuators creating movement in agricultural machinery, such as spreaders and sprayers, it is almost inevitable that they will be exposed to various chemical compounds. For actuators operating on board blue water yachts, exposure to salt is sure as fate. LINAK manufactures solutions for both types of applications, and to ensure flawless and reliable performance, we test the actuators thoroughly.

LINAK industrial actuators have spent 500 hours in a salt spray chamber with a temperature of 40 °C and a relative humidity (RH) level of 93%. They have been brushed with various chemicals repeatedly, each time leaving the compound on the actuator for at least 100 hours.

That is why you can rely on your LINAK actuator!

Why corrosion tests are important
When it comes to corrosion due to salt or strong chemicals, defective equipment is not only a costly affair. In a worst-case scenario, it can be dangerous to the person operating the application, if the actuator stops working properly.

Dealing with corrosive compounds in agriculture
For farmers using fertilizers, reliability is a number one priority. Actuators on, for example, a spreader or a sprayer are frequently exposed to some very aggressive substances. Their housings and sealings must be able to withstand these substances, allowing the actuator to operate unhindered for many years.


To ensure the necessary ingress protection, our industrial actuators are applied with chemicals, such as diesel, hydraulic oil, ethylene glycol, urea nitrogen, and NPK fertilizer. The actuators must pass a full performance test following these ordeals.

Wear and tear from the ocean’s salt
Electric actuators are used to increase comfort on yachts all over the world. But as every experienced sailor knows, nothing takes a toll on a ship and its gears as much as the combination of salt and sun. Fluctuating temperatures and changes in humidity do nothing to help either.

Extensive testing against concentrated salt vapors helps ensure that actuators continue to deliver full performance throughout their life, operating in one of the harshest and most demanding environments on Earth.
