Enerpac aluminum cylinders are a lightweight solution for double-acting applications. Double-acting for rapid retraction, regardless of hose lengths and system losses. Composite bearings increase cylinder life and side load resistance. Hard coat finish on all surfaces resists damage and extends cylinder life. Handles included on all aluminum cylinder models. Steel base plate and saddle for protection against load-induced damage. Integral stop ring prevents plunger over-travel and is capable of withstanding the full cylinder capacity. Built-in safety valve prevents accidental over-pressurization.
