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
HP revealed more of its 3D printing plans in a recent webinar. Senior vice president of inkjet and graphics solution business Stephen Nigro spoke about how the technology works and expanded on HP's vision of open collaboration to commercialize its Multi Jet Fusion 3D printing technology for end-production, and open collaboration on new materials. He also said HP will create software to help users decide when to use Multi Jet Fusion versus conventional subtractive manufacturing.
The Dutch are known for their love of bicycling, and they’ve also long been early adopters of green-energy and smart-city technologies. So it seems fitting that a town in which painter Vincent van Gogh once lived has given him a very Dutch-like tribute -- a bike path lit by a special smart paint in the style of the artist's “Starry Night” painting.
