Universal Design for Ultimate Flexibility

The K Series actuators from Exlar provide a truly universal solution for a multitude of rod-style actuator applications. Now available in 60, 75, and 90 mm frame sizes.


Big Performance and Small Form Factor

These robust electric actuators provide an ideal replacement for pneumatic cylinders and feature comparable dimensions with a similar form factor. The optional roller screw drives are a superior replacement for hydraulic cylinders. Better performance, greater flexibility, and longer life culminate to make the K Series a smart choice for many applications.


Multiple Models to Exactly Fit Your Needs

KX Series actuators are offered in three frame sizes, so you can choose the option that best suits your application requirements:


 KX actuators

The high performance planetary roller screw in the KX class offers performance that is far superior to competing actuator technologies. These actuators are ideal for industrial automation, mobile equipment, process control and many other demanding applications.


KM actuators – Legacy product

The standard capacity and lower cost planetary roller screw in the KM class is most appropriate for applications where cost is a higher priority than long life. Nevertheless, these actuators provide twice the life of similarly sized ball screw actuators, along with high efficiency and greater shock resistance.
