NR  WIPERS
THIS SECTION DESCRIBES A SYSTEM OF WIPERS  DESIGNED FOR PROTECTION OF THE RODS OF HYDRAULIC AND PNEUMATIC CYLINDERS
GENERAL FEATURES: FIELD OF APPLICATION:
  • Minimum encumbrance
  • Very low friction
  • Protected wiper lip
  • High temperature resistance
  • Ample chemical resistance range
 T max.  120 °C
up to 250 °C with special materials
Linear Speed up to 5 m/sec

 
NR WIPERS  are made up of a wiping element in modified PTFE and an O-Ring which is the energyzer element.
The particular profile and the choice of materials make an extremely reliable component for completely preventing the penetration of solid and liquid contaminative elements in the mechanical organs.
Appliance: Protection of the cylinder rods of industrial equipments.
ADVANTAGES
  • Long life.
  • Low friction resistance.
  • Closed groove installation.
  • Minimum groove encumbrance.
  • Complete reliability due to the energyzed lip and the sharp and compact wiping edge.
  • Complete seal against contaminating fluids.
