Haydon Kerk Motion Solutions (www.haydonkerk.com) has unveiled the SRA04 Motorized ScrewRail Linear Actuator that features an integrated size 11 stepper motor.
Unlike traditional two rail system, this motorized ScrewRail saves space by as much as 80 percent. The simplified design, assembly and manufacture of its motion system eliminate the need for an external rail-to-screw alignment.
The ScrewRail is comprised of a Kerk precision rolled lead screw contained in a concentric steel guide rail and supported by sealed ball bearings. Its self-lubricating nut/bushing material and KerKote TFE coating guarantees zero maintenance and longer life. Capable of simultaneously lifting and rotating (Z-theta motion) when mounted vertically, the ScrewRail is suitable for pick-and-place mechanisms. It is available both in anti-backlash (SRZ) and freewheeling (SRA) nut assembly and is offered in up to 72-inch stroke length.
It utilizes a size 11 Haydon hybrid double stack stepper motor, which comes with an integral connector or flying leads. Its RoHS-compliant connector that is rated up to three amps, provides a positive latch to deliver high connection integrity. Meanwhile, its mating connector supports various wire sizes that range from 22 to 28 gauge.
Aside from pick-and-place mechanisms, the SRA04 motorized ScrewRail is also ideal for robotic assemblies in semiconductor equipment, life sciences instrumentation, packaging and assembly, business machines, and a vast array of factory automation applications. Used together with the company’s extensive offering of motion control components, customers can create their own custom systems for numerous kinds of motion.
