Two relatively rotatable members (11, 14) are sealed by a sealing assembly (21) mounted in a recess (15) in the member (11). The sealing assembly consists of an annular metal diaphragm (22) consisting of a base portion (25) which is press fined into the recess, a flexible connecting portion (27) and a stiffener portion (26). Moulded onto the annular diaphragm is a seal ring (23) which seals against the peripheral wall (20) of the recess, covers the diaphragm, and provides a sealing lip (31) which is urged against a confronting surface (18) of the second member (14) under the action of a Belleville spring (24) which acts between a flange (35) on the diaphragm and the stiffener portion (26) of the diaphragm. |
