Abstract
An axial shaft sealing unit for sealing a stationary machine part relative to a rotatable machine part. The sealing unit includes a slide ring seal mounted on the stationary machine part in a sealing manner and includes a housing with a bottom located transversely to the axis of the slide ring seal, a primary seal forming a sliding ring, a bellows-like secondary seal, and a compression spring arranged between the primary seal and the housing bottom or base. The bellows-like secondary seal is vulcanized in a position which corresponds substantially to its installed position and is held in this position in its operative state by a detachable holder. A counter ring rests directly against a machine component which is non-rotatably connected to the rotatable machine part.
