SEAL SGJM

The SGJM profile is a dust seal for suspension systems composed of an elastomer-coated metal cage and a primary sealing lip with an external spring.

CHARACTERISTICS

Good static sealing.
Good compensation for thermal expansion
Allows roughness in the casing.
Reduced risk of corrosion.
Sealing for low- and high-viscosity fluids
Modern primary sealing lip with low radial forces
Acts as a dust cover for suspension systems.

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.
