A slide ring seal arrangement comprises a rotationally fixed slide ring (4) and a slide ring (11), which is provided for rotating together with a rotating component, these slide rings each being held in a loose seat and interacting, in, in essence, radially oriented sealing surfaces, which are prestressed with a main prestressing force while in contact with one another. Each slide ring, on its front face that faces away from the sealing surface, is axially supported on a supporting part (14, 17) via an annular bearing surface (16, 20) provided between the respective supporting part and the adjacent front face of the respective slide ring. A load ratio (d12−dH2)/(d12−d22) of =2.0, preferably between 0.8 and 2.0, preferably no greater than between 1.0 and 1.5, more preferably approximately 1.3 is maintained on the bearing surface (16, 20). The measurement (d1−d2) of each bearing surface (16, 20) is equal to =10 mm, preferably between 0.2 and 2.0, preferably no more than approximately 0.6 mm.
A slide ring seal arrangement comprising a non-rotatable slide ring and a slide ring provided for rotation in common with a rotatable component, said slide rings being held in a loosely restrained manner and comprising co-operating, substantially radially aligned sealing surfaces biased into engagement with one another by a main biasing force, wherein each slide ring is axially supported at a side thereof facing away from its sealing surface, by a corresponding support component of a pair of support components, one of said support components being provided for rotation in common with said rotatable component and the other of said support components being non-rotatable, via an annular contact surface, said annular contact surfaces being provided respectively between a respective one of said support components and an adjacent side of one of said slide rings that faces away from the sealing surface of thereof, wherein a load ratio (d12−dH2)/(d12−d22) of each contact surface is about 1.3 wherein the dimension (d1−d2) of each contact surface is about 0.6 mm, and wherein:
