ABSTRACT:
A mechanical face seal has a first seal face member mounted in fixed rotational and axial relationship and sealed with respect to a housing, and a second seal face member mounted with respect to a shaft by means of an elastomeric bellows unit, the bellows unit being axially compressed so that it urges the second seal face member into sealing engagement with the first seal face member; the elastomeric bellows unit being formed from an elastomeric composition with reinforcing fibres embedded therein, the reinforcing fibres being orientated axially of the bellows unit.
