Linear Actuators


Attuatori Lineari - K


The KX 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. Two grades of planetary roller screws and an ACME screw alternative give you flexibility to select the configuration that is best suited for your application and budget.

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.


K Series actuators are offered at three performance levels, so you can choose the option that best suits your application and budgetary requirements:


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.



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.



The ACME screw alternative in the KA actuator is best suited for low duty cycle applications. It provides a non-back-driving solution with a 2.54 mm lead. These actuators are a good choice for applications that simply need to position and hold a load or those that only require low duty cycle, electro-mechanical motion.
