Abstract: A rotary seal arrangement includes a first machine part being a shaft and a second machine part encompassing the shaft. The first and second machine parts are spaced apart and rotatable relative to one another forming a sealing gap. A seal holding structure is formed on one of the two machine parts. A rotary seal has a foot section and a sealing lip connected via a connecting section. The foot section is arranged on or in the seal holding structure. The sealing lip rests sealingly on a sealing surface of the respective other machine part to seal an oil side from an outside of the rotary seal arrangement. On the oil side there is a foam ring with a base body and with a holding section which surrounds the first machine part and which is held on the foot section of the rotary seal via the holding section.
