A sealed joint assembly includes an outer joint part ( 3 ) with outer ball tracks ( 9 ), an inner joint part ( 4 ) with inner ball tracks ( 10 ), torque transmitting balls ( 6 ) which are guided in pairs of tracks and held in a cage ( 7 ) with cage windows ( 8 ). A sleeve ( 16 ) is connected to the inner joint part ( 4 ) and is coaxially arranged thereto. A sealing mechanism ( 12 ) with an annular cap ( 13 ) is fixed to the outer joint part ( 3 ) and includes a sealing diaphragm ( 15 ) with an outer collar ( 18 ) connected to the annular cap ( 13 ) and an inner collar ( 19 ) sealingly connected to the sleeve ( 16 ). A securing ring ( 20 ) fixes the inner collar ( 19 ) on the sleeve ( 16 ). The sleeve ( 16 ) has an annular groove ( 33 ) which is engaged by the sealing diaphragm ( 15 ) by an inner annular bead ( 32 ) formed on the inner collar ( 19 ).
