Designed to promote increased reliability and machine uptime by protecting against potential damage caused by the passage of electric currents in ac and dc motors, the INSOCOAT electrically-insulated rolling bearings feature a thin aluminum oxide layer. The layer is meant to form an excellent barrier against electric arcing, which typically causes fluting damage to roller and raceways or grease oxidation. They have performance tested to 1,000V dc with a minimum ohmic resistance of 50M.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
