Slipper Composite seals : profile list


MIDDLE  COMPOSITE SLIPPER SEALS FOR HYDRAULICS AND PNEUMATICS

 

SLIPPER
  • A dinamic contact ring in Neuflon-ptfe compound expanded by an O-Ring for elastic compensation and accumulation

APPLICATIONS
  • In high speed and pressure fluid dynamics even in absence of lubrication, in analogical regulators and controllers, servo-systems and for all those uses where general high reliability is required

CHARACTERISTICS
  • Double action sealing
  • Very low friction
  • No stick-slip
  • Installation in closed grooves and minimal encumbrance
  • Supplied in all sizes and many profiles
  • Long life
  • High reliability
  • Resistance to the "diesel effect"
  • Ample chemical and termal resistance
  • High extrusion resistance
  • No sticking
SUGGESTED FINISH FOR THE SEALING SURFACES
  • Sliding surface             Ra  0.2 - 0.3 micron   (scouring or rolling should follow the grinding)
  • Static surface               Ra  0.5 - 0.6 micron
  • Groove inner surface     Ra  0.8 - 1.0 micron

HIDRODYNAMIC BEHAVIOUR

  Double action sealing. In dynamic applications it shows optimum sealing in both senses
  Double action sealing. In dynamic applications it shows optimum sealing in both senses. more suitable for high speeds. At low speed and in static conditions this profile performs better than the preceding one
  Single direction seal. In dynamic conditions it presents optimum sealing on the one hand and on the other it facilitates the return of the film of oil adherent to the sliding surface. Generally used for rod sealing in hydraulics applications
these profiles guarantee a longer life of the seal in conditions wherein constantly frequent levels of extreme pressure are reached
 Double action seals for keeping  different fluids separate, e.g. gas / oil
  Single acting seals for pressure intensifiers, water cutting and pressure multipliers
PISTON PRODUCTION PROGRAMME ROD

Standard SLIPPER series N

  • Used in hydraulics and pneumatics
  • Max. pressur 800 bar and over in particular conditions
  • Speed up to 5 m/sec
  • Temperature range -60 a +200 °C

The N series is suitable for the most difficult conditions of use and the most extensive clearence
recalibration is needed if installed in closed grooves

High Response SLIPPER series H

  • Used in hydraulics and pneumatics
  • Max. pressur 600 bar and over in particular conditions
  • Speed up to 5 m/sec
  • Temperature range -60 a +200 °C

The H series is suitable for the most difficult conditions of use and is suggested instead the N series when a fast response to the pressure is required
recalibration is needed if installed in closed grooves.

Light SLIPPER series L

  • Used in hydraulics and pneumatics
  • Max. pressure 100 bar and over in particular conditions
  • Speed up to 5 m/sec
  • Temperature range -60 a +200 °C

The L series is the standard for use in pneumatics. It can be used in oleodinamics too, mantaining the clearance at a minimum

Ultra-Light SLIPPER series
Little encumbrance Slipper seal to fit O-Ring grooves

  • Used in hydraulics, pneumatics and chemical industry
  • Max. pressur 300 bar and over in particular conditions
  • Speed up to 5 m/sec
  • Temperature range -60 a +200 °C

When O-Rings stick, wear or extrude. It also allows the use in dynamic applications of O-Rings whose compound is for static sealing only

ROTOSLIPPER

  • Used in hydraulics
  • Slow rotational movements, fast translational movements and combined roto-translational movements
  • Max. pressur 800 bar
  • Temperature range -60 a +150 °C

 


Slipper  NPQ  series  double acting piston seals

 

 
  • Applications: oleopneumatics and all  applications where separation of different fluids is required
  • Pressure max. 400 bar
  • Speed max. 0.5 m/sec
  • Temperature range -35 a +100°C
     and more with speciale compounds
