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 Exlar 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.

 

Other Advantages

  • Flexible design suitable for numerous applications and configurations
  • Universal mounting options compatible with DC, stepper, and servo motors
  • Preconfigured parallel and inline motor mounts available for most motors
  • Multiple models for maximum flexibility
  • Anodized aluminum housing with sealed body options for harsh environments
  • Specialized material and coating options
  • Built for long life and low maintenance

1 - Input torque should be limited such that Max Force is not exceeded. For a parallel belt ratio, the input torque ratings must be divided by the belt ratio for allowable motor torque. The output force ratings remain the same.
2 - Maximum allowable actuator–generated force that can be applied routinely. Exceeding this force may result in permanent damage to the actuator. For maximum allowable externally-applied axial forces, consult factory. For high force, short stroke applications, consult factory.
