D/A Aluminum Cylinders

• Integral stop ring prevents plunger over-travel and is capable of withstanding the full cylinder capacity
• Built-in safety valve prevents accidental over-pressurization
• Hard-Coat finish on all surfaces resits damage and extends cylinder life
• Handles standard on all models
• Double-acting for rapid retraction, regardless of hose lengths and system losses
• Composite bearings prevent metal to metal contact, increasing cylinder life and resistance to side-loads of up to 10%
• Steel baseplate and saddle for protection against load-induced damage

Aluminum vs. Steel

Aluminum cylinders, while offering the most lightweight solution for many lifting, stressing and lowering applications, also have some unique limitations due to material properties. Aluminum differs from steel in that it has a lower finite fatigue life. This means aluminum cylinders should NOT be used in high-cycle applications such as production. The Enerpac line of aluminum cylinders are designed to provide 5,000 cycles at their recommended pressure. This limit should not be exceeded. In normal lifting and many maintenance applications, this should provide a lifetime of use.
