K90 linear actuators from Exlar (Chanhassen, MN) are compact, 90-mm frame size actuators available in three performance levels, and allow the use of third-party motors. Featuring dimensions and form-factor consistent with ISO Metric pneumatic cylinder specifications, the actuators are designed to provide a universal solution for linear motion rod-style actuator applications. Three models offer two grades of roller screws and one Acme screw. KX90 actuators incorporate a high-performance planetary roller screw for applications in industrial automation, mobile equipment, process control, and other applications requiring millions of inches of travel under load.KM90 models employ a lower-cost planetary roller screw for applications lacking the same longevity requirements offered in the KX Series, while providing resistance to shock. KA90 actuators utilize an Acme screw, making them suited for slow-speed, low-duty cycle applications where the load must occasionally be repositioned during operation. The K Series actuators are available in a variety of special materials and coating options for applications that require a higher level of corrosion- resistance.
