Exlar KX
Mechanical roller screw actuator

• Roller screw actuator up to 15,6 kN
• Including motor adapter and coupling
• 150-900 mm stroke - 833 mm/s

The KX series linear actuator from EXLAR provide a universal solution for a wide variety rod style actuator applications up to 15,6 kN. Depending on the loads the K series actuator is available with multiple grades of high-performance planetary roller screw.

Multiple models to fit your needs The KX series provides an ideal replacement for pneumatic cylinders, with dimensions and form factor consistent with ISO Metric pneumatic cylinder specifications. Additionally, the high-performance roller screw drive allows the K series to replace hydraulic cylinders, providing a solution that offers superior life and performance to ball screw actuators, for high forces up to 15,6 kN. The K series offers users the choice of motor brand and type, including brushless servo, stepper, DC or AC motor. Input transmission options include parallel motor mounts with belt transmissions. Ratios of 1:1 to 2:1 are offered standard. Additional options include a direct drive inline mount or a base unit without motor mounting provisions. The standard K series actuator design provides an anodized aluminum housing for excellent corrosion resistance use in many environments. The standard main rod is nickel plated steel providing excellent wear characteristics. For extreme conditions the aluminum actuator body components can be provided with alternative coatings, such as Type III hard coat anodizing, electroless nickel plating or epoxy coating. The actuator's main rod can be provided in stainless steel construction. The K series offers a wide variety of fixed and adjustable mounting accessories, consistent with ISO Metric pneumatic cylinder standards. EXLAR also offers the user the rare option to have an inline mounted EXLAR servo motor with a rear clevis or rear eye mount for pivoting applications. Mounting options include:

• front flange
• rear flange
• rear clevis
• rear eye
• adjustable side trunnions
• end angles
• foot mount

X-Y manipulator with Exlar actuator

Optimize an existing X-Y manipulator by improving the cycle time by approximately 30%. By replacing a pneumatic cylinder with an electric actuator from Exlar, it is possible to make a parabola-like controlled movement and realize the desired time savings.

The actuator (duty cycle = 24/7) must be able to lift a load of approximately 75 kg with a high frequency in a dirty environment with dust, grease, welding spatters, etc.
