Tolerance recommendation

DF
H8

The tolerance definition for the dimensions D and dF must be viewed in connection with the seal used. The diameter D1 specified in the dimensions is to be viewed exclusively in relation to the guide ring. The corresponding diameter of an adjoining seal housing should be tailored to the sealing component.
