Linear Actuator Applications

Linear Actuators are part of our motion product portfolio. They are described as a device which converts rotary motion into linear motion.

Linear actuators are available in different styles and configurations this makes them suitable for many different applications in a wide range of industries. Linear actuators are fast becoming a vital device within motion control.

Linear Actuators comprise of an AC or DC motor, gearing and a lead or ball screw with driving nut. As the motor rotates, the screw also rotates forcing the nut along the shaft and whatever is being controlled by the actuator will move linearly.

Linear Actuator Applications

Because a linear actuator can be used to either push or pull with the same force, its applications involve lifting, lowering, sliding, adjusting and tilting objects.

Linear Actuators are very versatile and can be used for applications in many different industries. They are used to either push, pull, lift, lower, slide, adjust and tilt objects. Some areas for use are;

Food processing – With specialised washdown variants available

Robotics – Linear actuators are used within robotics to control repetitive movements; they can control the acceleration rate and the force applied. As robotics becomes more prevalent within automation, this is a more common use for linear actuators than ever before.

Packaging – Linear actuators have long been used in packaging applications, flexibility is key in this industry and linear actuators can provide a reliable solution.

Agriculture – Applications including adjusting spreading flow in various machines, providing motor accelerator, adjusting header cutting angles and more.

Factory automation – Linear actuators are often selected for applications in factory automation as they are highly accurate, efficient and reliable.

Automotive inc Mobile off-highway vehicles – Within these types of applications linear actuators need to be resistant to various factors including; vibration, shock and aggressive chemicals whilst still delivering high precision.

HVAC – Within heating ventilation and air conditioning there are various applications for linear actuators.

Materials handling – Linear actuators are required in every type of manufacturing operation.

Marine – Linear actuators are used to adjust helms, operate doors, lift tables and regulate valves.

Other applications using linear actuators include;

  • Machine tool
  • Lawnmowers
  • Printing
  • Construction
  • Defence
  • Aerospace
  • Industrial Machinery
  • Clean Energy

Linear Actuator Benefits
