New Exlar K Series Actuators Improve OEM Competitiveness with Multiple Model Types to Suit Every Application & Budget

The new Exlar K Series of linear actuators from INMOCO are designed to improve OEM competitiveness, with a range that offers multiple model types, enabling users to chose the option best suited to their application and budgetary requirements. Providing a truly universal solution for rod style actuator applications, the K Series actuators use Exlar’s patented roller screw technology, with its proven reliability and superior load carrying capacity, and allow the user the choice of multiple - and lower cost - motor technologies.

The price/performance ratio of the K Series electromechanical actuators means that they provide a clean, fast, simple and cost- effective replacement for hydraulic actuation, delivering a solution that offers superior life and performance. In addition, with dimensions consistent to those for ISO Metric pneumatic actuators, the K Series units also provide a simpler, longer- life alternative to pneumatic cylinders.

The K series is available with the option of multiple grades of planetary roller screws and with an option for an ACME screw for applications where backlash cannot be tolerated. The patented roller screw mechanism enables Exlar to provide some of the most reliable, long-lasting electro-mechanical actuators on the market. The design of the roller screws allows them to be accelerated and rotated faster than comparably sized ball screws, while their large contact area allows high force characteristics, and provides long life - typically 15 times that of comparably sized ball screws - even in the most demanding repetitive applications:

The robust design of the K Series actuator design ensures reliable performance in demanding applications. The actuators are enclosed in anodised aluminium housings that ensure excellent corrosion resistance and reliable operation in many arduous environments. They also benefit from main rods manufactured from nickel plated steel as standard, ensuring excellent wear characteristics from the actuators.

Last but not least in terms of environmental performance, the standard body design of the K Series provides an IP65 sealed housing and motor mount, (when allowed by the design of motor used). This allows the actuators to be used in applications where spray is present, without the requirement – and cost - of special options.

For applications not served by the standard K Series product design, Exlar offers a variety of special materials and coating options. The aluminium actuator body components of the K series actuator can be provided with alternative coatings such as Type III hard coat anodising, electro-less nickel plating, epoxy coating, or paint. In addition, the actuator main rod can be provided in stainless steel for greater corrosion resistance.

The K Series actuators provide users with complete flexibility in the type and style of motor to be mounted to the actuator. The user can select mounting provisions for brushless servo motors, stepper motors, DC brushed motors, and any other motor type that will fulfill the actuation requirements.

Complementing its adaptability to multiple motor types, the K Series offers what is probably the most flexible mounting system available with linear actuators today. The mounting options include: front and rear flange, rear clevis, rear eye, adjustable side trunnion, end angles, foot mount and inline Exlar servo motor with rear clevis.

The initial launch of the K Series actuator covers two models, the KM60 and KX60. The KM provides an economical planetary screw design unit, yet with superior performance to ball screw units. The KX delivers maximum thrust and life from its high performance planetary roller screw.
