A ring arrangement with a synthetic material sealing ring between an outer radial guiding ring and an inner radial guiding ring, wherein the outer guiding ring has a greater coefficient of thermal expansion than the inner guiding ring, so that an effective volume expansion coefficient of an annular gap between the guiding rings is greater than the volume expansion coefficient of the synthetic material of the synthetic material sealing ring. Through a large effective coefficient of thermal expansion for the annular gap volume, as achieved via different coefficients of expansion of the outer and inner guiding rings, fluctuation of the axial clamping forces of the synthetic material sealing ring can be limited. |
