Mechanical seal arrangement having a bellows element

Mechanical seal arrangement, comprising:

• a rotating slide ring and a stationary slide ring which define a sealing gap therebetween, and
• a bellows unit with a bellows element and an intermediate disk,
• wherein the bellows element has a first connection region, a second connection region and a bellows intermediate region,
• wherein the bellows element is produced from an elastomer material and provides a connection between the rotating slide ring and a rotating component,
• wherein the intermediate disk is arranged between the bellows element and the rotating slide ring, wherein the intermediate disk defines a longitudinal center axis, and wherein the intermediate disk includes a first axial facing surface and a second axial facing surface, wherein the first and second axial facing surfaces are spaced apart from one another along the longitudinal center axis, wherein the intermediate disk defines an inner peripheral region between the first and second axial facing surfaces, wherein the intermediate disk lies with the first axial facing side against a rearward side of the rotating slide ring and lies with the second axial facing side against a step of the bellows element;
• and
• wherein the inner peripheral region of the intermediate disk is arranged for support on the rotating component, wherein a multiplicity of recesses are provided on the inner peripheral region of the intermediate disk to allow for axial movement of the intermediate disk, wherein each of the multiplicity of recesses extends longitudinally from the first axially facing surface to the second axially facing surface,
• wherein the intermediate disk has at least one region, which protrudes from the intermediate disk in an axial direction, for locking the intermediate disk against rotation relative to the bellows element and the rotating slide ring.
