Exlar, a business group of Curtiss-Wright Controls (Chanhassen, MN), offers the K Series™ linear actuators with a 75-mm frame size. They combine roller screw technology in varying performance levels, and allow the use of third-party motors. Along with 60-mm and 90-mm frame sizes, the actuators feature dimensions and form-factor consistent with ISO Metric pneumatic cylinder specifications for pneumatic and hydraulic replacement. They are compatible with any type and style of motor such as DC, stepper, and servo, and offer universal mounting configurations. They offer standard stroke lengths up to 48 inches. The standard body design provides an IP54S sealed housing with options available for IP65S sealing. A variety of materials and coatings is also offered, such as Type III hard coat anodizing, electroless nickel plating, and epoxy coating.
KX75 actuators incorporate a planetary roller screw, and are suited for industrial automation, mobile equipment, process control, and other applications requiring millions of inches of travel under load. KM75 actuators employ a planetary roller screw for applications lacking the same longevity requirements. KA75 actuators utilize an Acme screw, making them suited for slowspeed, low-duty-cycle applications where the load must occasionally be repositioned during operation.
