OIL SEAL OVG
The OVG profile is a radial seal with a rubber-coated metal cage and a springless primary sealing lip. The sealing lip is placed on the outside. Grooved inner for easy assembly.
CHARACTERISTICS
- Very good static sealing.
- Good compensation for different thermal expansions.
- A higher surface roughness of the bore is allowed.
- Reduced risk of corrosion.
- Sealing for high-viscosity fluids
- Primary sealing lip that generates low levels of friction and heat
- Grooved inner to facilitate assembly.
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.
