Joyce/Dayton Stainless Steel Machine Screw Jack / Linear Actuators are specifically designed for positioning or lifting applications in corrosive or other potentially contaminated environments. All exposed surfaces and components feature 316 or 17-4 stainless steel construction and bronze bushings. Nitrile rubber seals protect all internal mechanisms.

Unlike other stainless steel screw jacks, Joyce/Dayton SWJ series provide full lifting capacity. In most cases, these jacks can be easily retrofitted into applications where non-stainless steel screw jacks have already been installed..

Joyce/Dayton offers Stainless Steel Screw Jack models in capacities from 2 to 25 tons. Stainless Steel Screw Jacks come in translating screw, rotating screw (keyed for traveling nut) and keyed (shown).

Stainless steel screw jacks are available with one of four standard screw ends or special ends to meet your requirements. For increased travel speed, specify DSWJ double lead series.
