Motorized Screwrail Linear Actuator

Motorized Screwrail Linear Actuator

Haydon Kerk Motion Solutions Inc.'s SRA04 Motorized ScrewRail Linear Actuator with an integrated size 11 stepper motor is compact, and can save as much as 80 percent 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 guide 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, the ScrewRail can be used to simultaneously lift and rotate (Z-theta motion), making the unit useful for pick-and-place mechanisms. Up to 72 inch stroke length is available.

The motor used on the unit is the Haydon size 11 hybrid double stack stepper motor. The stepper motor is available with either flying leads or an integral connector. The connector is RoHS compliant and features a positive latch in order to insure high connection integrity. The connector is rated up to 3A and the mating connector will handle a range of wire sizes from 22 to 28 gauge. Typical applications for the SRA04 motorized ScrewRail 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
