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 For protection against load-induced damage, a saddle is standard on all models and a steel baseplate is optional on 10- and 15-ton models. 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 included on all models All cylinders meet ASME B-30.1 standards
