Zusammenfassung:	The utility model relates to a dustproof end face rotary sealing element which comprises a floating oil seal ring, an O-shaped ring and a floating oil seal seat, and the O-shaped ring is located in a sealing cavity between the floating oil seal ring and the floating oil seal seat. An O-shaped ring groove of an arc-shaped structure is formed in the sealing cavity, a friction structure is arranged at the contact position between the O-shaped ring and the O-shaped ring groove, and a limiting structure is arranged at the end, away from the inner side, between the floating oil seal ring and the floating oil seal base. Through the structural arrangement of the O-shaped ring and the O-shaped ring groove, the O-shaped ring is not prone to falling off, and the probability of sealing failure is reduced; friction can be increased through the friction structure arranged at the contact position of the O-shaped ring and the O-shaped ring groove, so that the mounting stability of the O-shaped ring is good; through the limit
