ニカルシール。 A bellows-type mechanical seal comprising a seal ring held by a bellows and a mating ring that slides in opposition to the seal ring, one of the seal ring and the mating ring is supported by a housing, and the other rotates with a rotating shaft. A stepped portion is formed on the side opposite to the mating ring of the seal ring, and one or more grooves are formed in the outer cylindrical portion,
A stepped portion is formed on the seal ring side of the adapter disposed at the end of the bellows, and one or more grooves are formed in the outer cylindrical portion, and a retainer is provided between the seal ring and the adapter. is arranged, and by fitting both sides of this retainer in the axial direction into both the above-mentioned steps, and fitting one or more protrusions protruding from each side in the axial direction into both the grooves, a seal can be achieved. A bellows-type mechanical seal characterized by a ring held by an adapter.
