AM Wiper Seal
Descriptions
Because of their special profile, the profile AM wiper rings prevent the penetration
of dust, dirt, grains of sand and metal swarf. Scoring is avoided to a great extent.
Therefore sliding surfaces will be protected, the service life of the seals will be extended.
Oversized diameters ensure a tight fit when assembled and prevent the penetration
of foreign particles at the outer diameter of the wiper. The profile AM wiper rings will
provide a neat closure at the cylinder; no special screwrings or holding plates are
required.
Features
• Good wear resistance.
• Suitable for fully automatic installation.
• High temperature resistance in case of
suitable compound selection.
• Excellent media resistance in case of
suitable compound selection.
Range of application
Hydraulic and pneumatic cylinders, valve lifters etc.
Operating temperature | -35 °C to +100 °C |
Pneumatics | -35 °C to +80 °C |
Sliding speed | ≤ 2 m/s |
Compounds
Standard compound for the rubber part of the wiper is a NBR elastomer with a hardness of approx. 90 Shore A (Z5053). Additionally, a large number of dimensions is also
available with FKM elastomer (Z5066).
Installation
The profile AM wiper rings are manufactured with a slightly oversized outer diameter
D, thus ensuring a secure press fit in the groove DH8 after installation. Any contact of
the wiper lip with piston rod eyes or other connecting parts should be avoided.
