RR-Series Double Acting Cylinders are the ideal choice whenever you need to retract the plunger quickly with precise control. These popular rams are rugged enough to withstand high-cycle and demanding job site uses - making them incredibly effective within both the construction and manufacturing industries. RR Cylinders are available in long stroke models to lift or push a load a greater distance, which will save you time and minimize or eliminate the need for temporary cribbing.
The collar thread, plunger thread, base mounting holes, removable saddle and optional accessories make these some of the most versatile cylinders available. Optional accessories include flat, grooved, and tilt saddles on models up to 75-ton. These are secured to the plunger for use both horizontally and upside down.
The RR range is extensive, with capacities ranging from 10 to 500 imperial tons (101 - 5108 kN), and maximum plunger strokes from 2.25" to 48" (57 - 1219 mm). Each RR Cylinder available for sale is rated for up to 10,000 psi (700 bar) and compliant with ASME B30.1.
