OIL SEAL PA2C
The PA2C profile is a radial seal composed of a single metal case with a rubber coating, a PTFE sealing lip and an anti-dust lip. The PTFE sealing lip offers high wear resistance.
CHARACTERISTICS
- Excellent chemical resistance.
- Wide temperature range.
- Low friction.
- Excellent wear resistance.
- Excellent dielectric properties.
- Good aging resistance.
- Good mechanical resistance.
With an anti-dust lip to prevent dirt.
See our gInstallation guide for oil seals to perform a correct installation of the seal.

TOLERANCE FOR THE INNER DIAMETER OF THE SEAL
The inner diameter of the sealing lip is always smaller than the shaft diameter. Depending on the shaft size, the sealing lip diameter is generally between 0.8 and 3.5 mm smaller than the shaft diameter.
