It was to replace leadscrews and linear ball slides, which require lubrication. The resulting device did the trick, cutting friction by an order of magnitude and totally eliminating cogging during linear motions. An inventor then converted the bearing into a linear actuator powered by a servomotor.</p></div> <div class="og_rss_groups"></div><p><a href="http://machinedesign.com/whats-inside/rolamite-linear-actuator-cuts-friction-and-complexity" target="_blank">read more</a></p> http://machinedesign.com/whats-inside/rolamite-linear-actuator-cuts-friction-and-complexity#comments What's Inside?

The <strong>Federal Highway Administration</strong> estimates there are over 45,000 structurally deficient or obsolete bridges in the National Highway System, plus another 248,000 deficient bridges on smaller roads. To cut the cost of replacing many of those bridges, engineers at <strong><a href="http://www.aitbridges.com" target="_blank">Advanced Infrastructure Technologies</a>,</strong> Orono, Maine, have developed a hybrid concrete-composite bridge that also saves time and raw materials.</p></div> <div class="og_rss_groups"></div><p><a href="http://machinedesign.com/whats-inside/rethinking-bridge" target="_blank">read more</a></p> http://machinedesign.com/whats-inside/rethinking-bridge#comments What's Inside?
