OIL SEAL OKC

The OKC profile is a seal with dust seal lip and inverted sealing, formed by a simple metal cage with an elastomer coating, a primary sealing lip without spring and an additional dust seal lip. For sealing rotating boxes.

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 generating low levels of friction and heat.
  • Protection against undesirable air contaminants.

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.
