Description

Model: RRH-1003

Series: RRH

Product Lines: Industrial Tools

  • The hollow plunger design allows for both pull and pushes forces
  • Double-acting for fast retraction
  • Nickel-plated, floating center tube to increase product durability.
  • Baked enamel finish for increased corrosion resistance
  • Collar threads for easy fixturing
  • Relief valves prevent damage in case of over-pressurization
  • Plunger wiper reduces contamination, extending cylinder life
  • Hardened and chromed piston reduces wear and corrosion
  • Hardened alloy steel guide ring eliminates over travel and provides support to reduce wear from off-center loads
  • High strength composite bearing provides support for off-center loads without damaging the cylinder walls
  • 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!
