ABSTRACT:
A sealing ring assembly consists of (i) a preferably unreinforced sealing ring (ii) a harder supporting ring adjacent an axial side of the sealing ring and having lips extending axially to overlap the sealing ring at both its radially outer and inner peripheries, the radially inner lip being axially shorter than the radially outer one, and (iii) a bearing ring separate from the supporting ring. In a double-acting assembly there are two rings (ii) and (iii) arranged successively and respectively at each axial side of the sealing ring.
