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?
