The 28000 series size 11 double-stack non-captive hybrid linear actuator features a design in which the lead screw runs axially through the center of the motor and must be restrained from rotating for proper operation. This is usually accomplished by attaching the screw to a non-rotating member of the mechanical assembly, and as the internal threaded rotor rotates the lead screw moves axially but does not rotate.
The linear actuator is available in resolutions from 0.003175 to 0.0508 mm per step and delivers thrusts of up to 133 N. The device suits applications requiring precise positioning and rapid motion such as medical equipment, semiconductor handling, valve control, X-Y tables, and handheld instruments.
