Enerpac Aluminum Lock Nut Cylinders provide mechanical load holding for extended periods. Hardened steel stop ring increases cylinder life and resistance to side-loads of up to 5%. Hard coat finish on all surfaces resists damage and extends cylinder life. Composite bearings increase cylinder life and side load resistance. Handles included on all 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. High-strength return spring for rapid cylinder retraction. CR-400 coupler and dust cap are included on all models. All aluminum lock nut cylinders meet ASME B-30.1 and ISO 10100 standards.
