Integrating a size 11 hybrid double stack stepper motor, the SRA04 motorized ScrewRail linear actuator from Haydon Kerk Motion Solutions eliminates the need for external rail-to-screw alignment. Highly compact, it can save as much as 80% of the space required by a traditional 2 rail system. The ScrewRail consists of a Kerk precision rolled lead screw supported by sealed ball bearings and contained within a concentric steel guided rail, driving an integrated nut and bushing. KerKote TFE coating and self-lubricating nut/ bushing material ensure long life and zero maintenance. The ScrewRail is available with either a freewheeling (SRA) or anti-backlash (SRZ) nut assembly. When mounted vertically, it can be used to simultaneously lift and rotate (Z-theta motion), making the unit ideal for pick-and-place mechanisms. Up to 72” (1,828 mm) stroke length is available. The stepper motor is available with either flying leads or an integral connector. Rated at up to 3 A, the connector is RoHS compliant and features a positive latch in order to insure high connection integrity. The mating connector handles a range of wire sizes from 22 to 28 gauge. Typical applications for the motorized linear actuator include pick-and-place mechanisms and robotic assemblies in life sciences instrumentation, semiconductor equipment, business machines, packaging and assembly, and a wide range of factory automation applications. Combined with the company’s broad offering of motion control components, the unit can be used to create custom systems for many types of motion. High reliability without the need for maintenance or adjustment makes the motorized ScrewRail well suited to the demands of precision motion applications.
