Tolerance for the inside diameter of the seal (Ød)

Free and without constraint, the inside diameter of the sealing lip is always smaller than

the diameter of the rod. The pre-tightening or interference denotes the difference between

these two values. Depending on the rod diameter, the diameter of the sealing lip is generally

considered to be less, between 0.8 and 3.5 mm.

DESCRIPTION

The TC4P profile is a shaft seal

composed of a single metal cage

with a rubber coating and a double

sealing lip with an integrated spring,

suitable for linear movements.
