RAR3010 309 kN Capacity, 250 mm Stroke, Double-Acting, Aluminum Hydraulic Cylinder

Enerpac RAR3010 is a lightweight, double-acting aluminum hydraulic cylinder designed for high-force pushing and pulling in confined spaces, ideal for industrial maintenance, construction, and tensioning tasks. With a 34.2-ton (309 kN) advance capacity and 250 mm stroke, this model offers rapid hydraulic retraction independent of hose length, operating at up to 10,000 psi with an integral stop ring for over-travel protection, composite bearings for side-load resistance, and a hard anodized finish for superior corrosion resistance and durability in harsh environments.
