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
Researchers at Lawrence Livermore National Laboratory have published two physics-based models for the selective laser melting (SLM) metals additive manufacturing process, so engineers can understand how it works at the powder and scales, and develop better parts with less trial and error.
The Internet happened.” Those three words spoken yesterday by Marc Ostertag, North America president of B&R Automation at Pacific Design & Manufacturing, now taking place in Anaheim through Feb. 11, continues to bring ever-lasting changes to our ways of life and will undoubtedly transform manufacturing.
