The seal cassette configured to seal off a space from an outside environment and includes a first circumferential element and a second circumferential element arranged coaxially and rotatably movable relative each other. At least one third circumferential element is provided and is arranged coaxially relative the first and the second circumferential element and further arranged to be rotatably movable relative the second circumferential element. The first circumferential element is formed as a sleeve extending in an axial direction (A). The second circumferential element provides at least one circumferential seal portion arranged to seal between the second element and the first element. The at least one third circumferential element provides at least one circumferential seal portion to seal between the third element and the second element and further provides a circumferential seal portion that seals against the first element.
