Our low pressure pneumatically actuated collet closers are double acting, pull-back design for use with "5C" style collets. These rugged units are made from solid aircraft aluminum. The force generated by the drawtube is 7.5 times the line pressure applied. The units feature working pressures to 150 PSI and come standard with a "5C" collet wrench. Lexair can supply precision machined standard collets, master collets and pads, emergency collets, serrated collets plus uniquely shaped collets by special order. We can also design and manufacture custom turnkey solutions to meet the demands of all your workholding requirements
