versatile joyce machine screw jacks lift andprecisely position all kinds of loads from 250 lbs.to 250 tons.

upright or inverted, these precision jacks operateat full capacity whether the load is in tension orcompression. wj series single lead jacks are selflocking under full lifting capacity. dwj doublelead series jacks offer increased travel speed.

heat treated alloy steel worm shafts, aluminum/bronze worm gears and tapered roller or ballbearings provide rugged reliability.

double extended worm shafts are standard.single extended worm shafts are available withright or left hand extension or additional length.joyce jacks come in translating screw (shown),rotating screw (keyed for traveling nut) and keyeddesigns. all jack designs can be fitted with a protective boot. jacks are available with one offour standard screw ends or special ends to meetyour re

an optional anti-backlash feature (see page 113)compensates for thread wear, assuring minimumplay between lifting screw and worm gear forsmooth, precise operation. jacks e withthe antibacklash feature are rated at full capacityunder static conditions. for jack capacity underdynamic conditions please contact joyce/dayton.joyce/dayton will custom design jacks to meet special re

ordering information—order must indicate model number, rise,upright or inverted configuration, translating, keyed to preventrotation (keyed) or keyed for traveling nut (kftn), type of screwend, with or without protective boot, etc.
