Single Acting, RAC series Aluminum Cylinders

RAC series

Aluminum Cylinders, Single- Acting

Composite bearings prevent metal to metal contact, increasing cylinder life and resistance to side-loads of up to 10%
Hard-Coat finish on all surfaces resists damage and extends cylinder life
Handles standard on all models
Steel base plate and saddle for protection against load-induced damage
Integral stopring prevents plunger over-travel and is capable of withstanding the full cylinder capacity
High strength return spring for rapid cylinder retraction
CR-400 coupler and dustcap included on all models
All cylinders meet ASME B-30.1 and ISO 10100 standards

Aluminium differs from steel in that it has a lower finite fatigue life. This means that aluminium cylinders should NOT be used in high-cycle applications, such as production.

The Enerpac line of aluminium cylinders are designed to provide 5000 full-pressure cycles. This limit should not be exceeded. In normal lifting and many maintenance applications, this will provide a lifetime on use.
