Haydon Kerk Motion Solutions Inc.'s SRA04Motorized ScrewRail Linear Actuator with an integrated size 11 stepper motor iscompact, and can save as much as 80 percent of the space required by atraditional 2 rail system.

The ScrewRail consists of a Kerk precision rolledlead screw supported by sealed ball bearings and contained within a concentricsteel 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 afreewheeling (SRA) or anti-backlash (SRZ) nut assembly. When mountedvertically, the ScrewRail can be used to simultaneously lift and rotate (Z-thetamotion), making the unit useful for pick-and-place mechanisms. Up to 72 inchstroke length is available.

The motor used on the unit is the Haydon size 11hybrid double stack stepper motor. Thestepper motor is available with either flying leads or an integralconnector. The connector is RoHScompliant and features a positive latch in order to insure high connectionintegrity. The connector is rated up to3A and the mating connector will handle a range of wire sizes from 22 to 28gauge. Typical applications for the SRA04 motorized ScrewRail includepick-and-place mechanisms and robotic assemblies in life sciencesinstrumentation, semiconductor equipment, business machines, packaging andassembly, and a wide range of factory automation applications
