Lightweight Lock Nut Hydraulic Cylinder, 54.9 Tons Capacity, 3.94" Stroke
Enerpac RACL504 is a lock nut hydraulic cylinder that features 54.9 tons of max advance capacity and a stroke of 3.94". A hardened steel stop ring increases cylinder life and resistance to side-loads by up to 5% and a hard coat finish on all surfaces resists damage and extends cylinder life. It has composite bearings that increase cylinder life and side load resistance. It has a steel base plate and saddle for protection against load-induced damage
The Integral stop ring prevents plunger over-travel and is capable of withstanding the full cylinder capacity. High-strength return spring for rapid cylinder retraction. The RACL504 includes a CR-400 coupler and dust cap. All cylinders meet ASME B-30.1 standards.
