A bellows-type mechanical seal construction having a rotating carbide face ring provided with a vibration damper mounted thereon. The vibration damper comprises a carbon ring which is fixedly mounted within the carbide face ring, as by a press fit. The carbon vibration dampener ring is of substantial axial extent, and provides a close clearance with a shaft to effectively dampen vibrations of the rotating seal parts.
