Metric Screw Jacks, series MWJ, are specifically designed for positioning and lifting applications that must be fully metric. These jacks are commonly used in OEM machinery manufactured in the U.S. and shipped to other countries around the world. They are fully interchangeable with several European products.
Metric screw jacks are available in four capacities:
10 kN, 25 kN, 50 kN, and 100 kN. MWJ screw jacks feature:
-
Industry standard metric (trapezoidal) lifting screw diameters and pitches.
-
Fully metric mounting hole locations, diameters and fasteners.
-
Alloy steel worm shafts and bronze wormgears and traveling nuts.
-
Tapered roller or ball thrust bearings provide rugged reliability.
Both upright and inverted configurations of these precision jacks operate at full capacity whether the load is in tension or compression. All MWJ jacks are self-locking under full capacity. Metric screw jacks are available with one of four standard screw ends or special ends to meet your requirements. Double input shafts are standard. An optional anti-backlash feature compensates for thread wear, assuring minimum play between lifting screw and wormgear for smooth, precise operation. All jack designs can be fitted with protective boots.
