SEAL TC4S

The TC4S profile is a double lip seal composed of a metal casing covered in rubber, and with an exposed spring. Special for automobile, motorcycles and bicycles shock absorbers.

CHARACTERISTICS

The semi-circular design of the secondary lip reduces friction and prevents reversal.
Special design for automobile shock absorbers.

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.
