Product Description

Series: RR Series

Product Lines: Long Stroke Hydraulic Cylinders

  • Collar threads and plunger threads for easy fixturing

  • Baked enamel finish for increased corrosion resistance

  • Removable hardened saddles protect the plunger during lifting and pressing

  • A built-in safety valve prevents accidental over-pressurization

  • Plunger wiper reduces contamination, extending cylinder life

  • The integral stopping ring provides piston blow-out protection

  • Double-acting, hydraulic return

  • Hardened and chromed piston reduces wear and corrosion

  • Hardened alloy steel guide ring eliminates overtravel 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

Think Safety

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