(1) New compound, used to be Z51
(2) New compound, used to be Z52


Operating parameters

Pressure (MPa): ≤ 40
Temperature (°C): -30 up to + 100
Speed: up to pv 6,5 MPa x m/s

Medium

  • Mineral-based lubricating greases
  • Synthetic and natural ester HEES, HETG up to +60°C
  • Flame retardant hydraulic fluids HFA, HFC up to +60°C


Z80 is recommended for sealing, for example, coolants or air



Benefits

  • Low friction
  • Stick-slip free start. Material does not stick
  • High wear resistance and dimensional stability
  • Simple groove design, small groove dimensions

Note: If the operating temperature is constantly above 60 ° C, the pressure and speed are limited.


Installation

De RD-20 is possible from 12 mm. be mounted in closed grooves. This depends on the material choice. The table below shows when the grooves must be open for assembly.
