RARH606 595 kN Capacity, 150 mm Stroke, Double-Acting, Aluminum Hollow Plunger Hydraulic Cylinder

Enerpac RARH606 is a lightweight, double-acting aluminum hollow plunger hydraulic cylinder optimized for tensioning, pulling, and pushing in confined spaces, offering superior efficiency over traditional steel models. With a 66.8-ton (595 kN) advance capacity and 150 mm stroke, it provides rapid hydraulic retraction regardless of hose length, operating at up to 10,150 psi with an integral stop ring for safety, composite bearings for side-load resistance, and a hard coat finish for extended durability in harsh industrial environments.
