Slipper Composite seals : rotoslipper

Prodotto:  NCSR housing on cylinder   NPSR housing on shaft

ROTARY SEALING SYSTEM FOR FLUIDICS

 

 
Slow rotational movements, fast translational movements and combined roto-translational movements
Max. pressure 800 bar
Temperature range -60 a + 150°C

 

Working conditions:
Rotational movements: up to 120 rpm with max peripheral speed of 0.6 m/sec and PV max 25 bar x m/sec
Translational movements: max 5 m/sec
At max temperature and/or in dry running conditions, pressure and speed should be adequately reduced.
Please contact our technicians for evaluating working conditions and the thermal analysis of the project.

 

CHARACTERISTICS

  APPLICATIONS
  • Biderectional sealing
  • Reliability and long life
  • Minimum grooves dimensions
  • Low rotation torque
  • No stick-slip
  • No sticking
  • Wide range of thermal and chmical resistance
  • Closed groove lodging
  • Hydraulic swivel joints at high pressure and low speed
  • Slow rotational movements, fast translational movements and combined roto-translational movements
  • The specially designed profile and the excellent quality of the O-Ring ensure exellente life-duration even if subject to continual pressure peak
  • For rotational use it is advisable to use the NCSR installed on cylinder whenever possible
  • FDA approved compounds for food and drug applications
