Hydraulic Production Vises • Innovative compact design • Internal hydraulics • 4,700 lbs (2,100 Kg) clamping force • Operates on lower input pressure • Fully machinable jaws • Fastest quick-change jaw system • Hardened stainless steel wear rails • Easy-Flow™ base design Jergens hydraulic vises are available in 3 different base con gurations. They offer the same unique features as Jergens manual vises. Technical Speci cations: Hydraulic Clamping Stroke: 1/4" (6.3mm) Operating Volume: 0.4 Cu In (6.7 cm3) Maximum Input Pressure: 4000 P.S.I. (275 bar) Minimum Input Pressure: 500 P.S.I. (35 bar) Input Port: #4 SAE (7/16-20 UNF-2B) Clamping Force (lbs) = Input Pressure x 1.19 Clamping Force (Kg) = Input Pressure Bars x 7.67 Operation: Using the Jergens Hydraulic Vise handle part number 49445, tighten vise jaws so the workpieces touch the xed jaw.
