Abstract
A device for fixing the sliding ring of an axial sliding ring seal for an axial rotary transmission leadthrough to a sliding ring support includes a conically tapered radial outer casing surface of the sliding ring and a holding apparatus designed as a cap nut and has a threaded section which can be screwed onto a matching external thread in the end area of the sliding ring support and also has a holding section which has a conically running internal surface which is matched to the conical casing surface of the corresponding sliding ring. The device has a higher degree of reliability and durability and is sufficiently space-saving to be able to replace existing rotary transmission leadthroughs in which the sliding rings are glued to the sliding ring supports.
