  • Enerpac hollow aluminum cylinders are a lightweight solution for tensioning and testing.
  • Hollow plunger cylinder design allows for both pull and push forces
  • Composite bearings increase cylinder life and sideload resistance
  • Hard-Coat finish on all surfaces resists damage and extends aluminium cylinder life
  • Floating center tube increases seal and product life
  • Handles standard 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 dustcap included on all models
  • All cylinders meet ASME B-30.1 and ISO 10100 standards.
