Aston Hydraulic Seals

DESCRIPTION   :-
Semicompact rod seal with an additional sealing lip.

MATERIAl:-

Type    :- Polyurethane
Designation  :- SEALPUR93
Hardness       :-93 sha

MAIN  FEATURES   :-

     wear  and dey run are largely prevented by additional lubricant retained within the gap created by the seconary lip.In some cases this second sealing lip may even act as a subsitute for a costly tandem sealing system when complete sealing under certain working condition can only be achieved by two seals placed one behind the other in separate housing.

          It's designed to be less sensitive to pressure fluctions then typical "u" seals.

           The material  used to produce this seal is a polyurethane compound that ensures excellent properties on wear - resistances, extended service life and resistance against extrusion.

•    Good sealing performance as well as low pressure
•    Extended service life
•     Excellant wear-resistance
•     Good tmpereture resistance
•     Insessitive to pressure function
•    Easy installation  without expensive auxiliaries.

DESCRIPTION
     Single acting piston seal with asymmetric lips.

MATERIAL :-

Type        :- Polyurethane
Desigation  :- SEALPUR93
Hardness     :- 93 sha
MAIN FEATURES  :-

       The piston seal type KD assures a good reaction against shock pressure peaks an dlow function in the liw pressure range.

          The asymetric  lips are designed to differntiate the behavier of the lips on the stasic and dynamic surfaces:the satic lip is flexible , more sensitive to pressure flucyuations and it guaranties a wide contact area: the dynamic lip is shorter and stronger to concentratr load against the dynamic surface.

         They can also be used in back-to-back  arrangement  for double acting piston.

•    Extended service life
•    Simole groove design
•    Insensitive  to structed defletions
•    High resistances against extrusion
•    Excellent wear-resistance
•    Good temperature resistance
•    Easy installation without expensive auxillaries.

FIELD  OF APPLICATION   :-

Pressure        < 400 bar

Speed            < 0.5 m/s

Temperature     -40 c %+ 100 c

Fluids                Hydraulic oils(mineral oil based).

DESCRIPTION  :-
                 Bi-directional rod wiper with shoulder  for pneumatic cylinders.

MATERIAL  :-

Type              : Polyurethane
Designation    : SEALPUR 93
Hardness        : 93 shA

MAIN FEATURES :-

    To prevent  introduction of dust , dirt and foreign matter into system;this is achieved by a special wiper lip which produces a very effective cleaning action, prevents the development of scores, protects the guiding parts and extends the service life of the axial moving rod seals.

      To prevent the release of air from the cylinder ensuring a perfect seal;the asymmetric lips are designed to differentiate the behavior of the lips on the static and dynamic surfaces: the dynamic lip is rounded,flexible and more sensitive to pressure fluctuations; the static lip is longer and stonger to concentrate load against the static surface.
     The material  used to produce this seal is a polyurethane compound.specifically developed for the production of pneumatics seals, that ensures excellent properties on wear - resistances , extended service life and low permanent deformation.

• Simple groove design
• Geometry of the sealing lips is designed to operate with air lubricated and dry
• Low friction at all usage pressure
• Easy installation without expensive auxiliaries
• Excellent wear-resistance
• Extended service life
