SEAL KOMSF15

The SF15 profile is a triple-lip seal composed of a metal case with a rubber coating and a polyurethane dust shield to enhance dust-proof performance. Specifically designed for agricultural machinery.

CHARACTERISTICS

Long service life.
Moderate/high rotation speeds.
Small axial displacements.
Intended for applications in agriculture, transmissions, and rotation during high levels of contamination.

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.
