The RFJ Series is Durapac’s lowest single-acting cylinder. Collapsed heights run from 1.28 in to 3.94 in, so it can go where there is almost no gap under the load.
Strokes are short, 0.25 to 0.63 in, which suits breaking a load free, making a first lift and small adjustments. Eight models cover 5 to 150 ton. CSK stack plate kits add height on the 5 to 30 ton sizes.
The bore and rod are hard chrome plated, a bronze overlay protects the piston bearing area, and a return spring retracts the rod.
