For vertical applications, Kerk lead screws can be designed to self-lock and prevent back driving, unlike traditional ball screws. Utilizing a sliding motion between the nut and the screw to convert rotary input to linear output motion, the Kerk non-ball lead screws offer accuracy comparable to ground ball screws. Kerk lead screws are manufactured with a choice of proprietary coatings, depending on the application requirements. Kerkote® and Black IceTM dry lubrication coatings eliminate the need for external lubrication and maintenance. Haydon Kerk Motion Solutions can also add value to an application by designing and molding customized application-specific nut features. As with all Kerk brand anti-backlash and freewheeling nuts, customized nuts can be molded using Kerkite® high performance polymers or various customer-specified specialty materials.
Manufactured from 303 stainless steel and produced with Haydon Kerk Motion Solutions’ exclusive precision rolling process, Kerk lead screws are available in standard diameters from 1/8 inch (3.2 mm) to 15/16 inch (23 mm), with standard leads from .02 to 3 inch (.5 to 76 mm). Custom materials, sizes and leads are available upon request.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
Biomedical engineering is one of the fastest growing engineering fields; from medical devices and pharmaceuticals to more cutting-edge areas like tissue, genetic, and neural engineering, US biomedical engineers (BMEs) boast salaries nearly double the annual mean wage and have faster than average job growth.
