  • The hollow plunger design allows for both pull and pushes forces
  • Composite bearings increase cylinder life and side load resistance
  • Hard coat finish on all surfaces resists damage and extends cylinder life
  • Handles included on all models
  • Floating center tube increases seal life
  • Steel baseplate 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
  • Plunger wiper reduces contamination, extending cylinder life
  • Hardened alloy steel guide ring eliminates over travel and provides support to reduce wear from off-center loads
  • An Industrial U-cup style seal prevents costly leaks

Think Safety

Manufacturer’s rating of load and stroke are maximum safe limits. Good practice encourages using only 80% of these ratings!
