Aluminum Hydraulic Cylinder, 54.9 Tons Capacity,7.87" Stroke
Enerpac RAR508 is Double-acting for rapid retraction, regardless of hose lengths and system losses with a Steel base plate and saddle for protection against load-induced damage. The Hard coat finish on all surfaces resists damage and extends cylinder life and Composite bearings increase cylinder life and side load resistance. The Handles are included in all models and the Integral stop ring prevents plunger over-travel and is capable of withstanding the full cylinder capacity. This Built-in safety valve prevents accidental over-pressurization.
Operate the hydraulic pump to advance and retract the cylinder. Some single-acting cylinders are spring-return, others are load return. The speed of retraction is affected by the length of the hose and other restrictions in the line. Double-acting cylinders are powered in both directions by the pump.
The cylinder stop ring is designed to take the full load. However, to reduce cylinder wear, use less than full stroke when possible.
NOTE: The manufacturer’s rating of load and stroke are maximum safe limits. Good practice encourages using only 80% of these ratings!

Pump Selection
A double-acting cylinder must be powered by a pump with a 4-way valve.
