OIL SEAL OUB

The OUB profile is an inverted sealing seal consisting of a simple metal cage without elastomer coating and a special triple flat lip design suitable for use in heavily soiled applications. Commonly used in agricultural equipment.

CHARACTERISTICS 
  • Good radial rigidity, particularly for large diameters.
  • Excellent stability after installation, effectively preventing any rebound effect.
  • Grease retention.
  • External contaminant retention (mud and water), environments with heavy- duty applications.
  • Suitable for rotating hubs with a fixed shaft.

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.
