S 663

DESCRIPTION

Type S 663 is recommended for medium application as a rod seal. Type S 663 has an asymmetric lips and is strictly designed as a rod seal. This means for example, overlap in the outer diameter in order to achieve tight fit in the groove. Thanks a special geometry of the inside diameter is achieved an excellent dynamic tightness and excellent properties of reverse-flow also in the rods with long stroke. Seal S 663 achieves excellent results in combination with  double wiper rings such as types A 846 or A 839.

MATERIAL

HYTHANE® is a special plastic with excellent wear resistent, flexible and high thermal resistant.

It is characterized by:

  • extremely good wear resistance
  • very low permanent compressive deformation
  • high flexibility
  • great flexibility in a wide temperature range

ADVANTAGES

  • excellent properties during the side displacement of rod
  • low friction
  • improved dynamic sealing properties
  • easy assembly

RANGE OF USE

PERMANENT TEMPERATURE: * from -40 °C to +100 °C
PRESSURE: to 400 bar
SLIDING SPEED: to 1 m/s

These are related values above. Interdependencies are shown in the next table.
* For water and pressure liquids HFA and HFB is permissible maximal temperature +60 °C.
For pressure liquid HFC is permissible maximal temperature +40 °C.

MEDIA

Seals from HYTHANE® are suitable for applications with air, water, pressure liquids based on mineral oil.
Temperature range is limited for HFA, HFB and HFC liquids.
