Actuators in the Defence industry
Olsen Actuators & Drives have a wealth of expertise in supplying Electric Roller Screw Actuators, rugged Defence rated Motor Drives and electro-mechanical solutions to the Defence sector.
Actuators are the component in a mechanical system which brings about linear or rotary movement. In the Defence Industry, we understand actuators need to be dynamic, robust, reliable, fast responding and often very powerful to replace legacy hydraulic fluid power systems.
Olsen Actuators & Drives have helped provide solutions for applications as varied as mounting controls, door-assist actuators, electric handling systems, subsea door actuators and loading mechanisms. We also specialise in designing motion platform solutions for simulation systems as well as testing rigs and process control on equipment from submarines to helicopters.
If there is something you need to move with more reliability, for longer and with significantly reduced maintenance then simply put, we can help find a solution to move it better.
Designed and tailored in the UK but shipped globally, our actuator solutions can incorporate integrated drive electronics, require no pipes or cooling and are incredible lightweight and compact in comparison with hydraulic or pneumatic systems. Electrical roller screw actuators deliver a highly accurate level of force and position control to solve some of the most challenging defence and security applications.
The longevity and low maintenance offered through our unique roller screw technology is particularly popular where product failure or downtime can be critical and very costly. Without the need for corrosive hydraulic fluids, which require a huge amount of maintaencance with the constant possibility of leaks or bursts, an electric solution has significantly lower through life support requirements.
The efficiency benefits are also significant. The huge operational energy, weight and space savings available, our actuators and solutions are proving even more desirable in an increasingly efficiency driven market.
Olsen Actuators & Drives are leading the way in pushing forward roller screw electro mechanical control systems. We are always happy to explore new applications, requirements and restrictions to find and develop new solutions to help drive the industry forward. If you have any questions regarding an existing project, or one in the pipeline, we would be happy help you.
