The option lets users fix a specific linear travel speed in one or both directions of travel using set screws which are inserted into the drive housing. No adjustments to motor speed or controls are necessary.</p></div> <div class="og_rss_groups"></div><p><a href="" target="_blank">read more</a></p> Mechanical Drives Thu, 07 Nov 2013 15:18:00 +0000 31891 at Disc-pack coupling uses friction to transmit torque <div class="node-body article-body"><p> The LP Survivor Series of disc-pack couplings from R+W America, Bensenville, Ill.
