HYDRODYNAMIC
BEHAVIOUR
|
 |
Double direction seal. In dynamic use it shows
optimum double direction sealing. |
 |
Double direction seal. In dynamic use it shows
optimum sealing in both senses. More suitable for high speeds. At low speeds
and in static conditions it presents virtually complete sealing. |
 |
Single direction seal. In dynamic conditions
it presents excellent 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 the rod seals in hydraulic applications. |
 |
These profiles guarantee an exceptionally
long life of the seal in conditions wherein constantly frequent levels
of extreme pressures are reached |
