SEAL OKG

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. It has a grooved on the inside to facilitate 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
Protection against undesirable air contaminants.
Grooved inner to facilitate assembly.

See our Installation 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.
