The invention concerns a clutch release bearing comprising an axially mobile piston (14), and a ring (26I), integral with a raceway (C1), hooked on the piston (14) with axial-effect squeezing elastic means (38, 40). The ring (26I) is provided with a proximal surface (F1, 62) and a distal surface (F2, 70) arranged axially behind the proximal surface (F1, 62). The proximal surface (F1, 62) is supported on a first hooking surface (A1, 64) provided in the piston (14). The squeezing means (38, 40) are supported on the distal surface (F2, 70) of the ring (26I) and a second hooking surface (A2, 76) provided in the piston (14). The first (A1, 64) and second (A2, 76) hooking surfaces provided in the piston (14) are arranged axially in front of the distal surface (F2, 70) of the ring (26I) The invention also concerns a method for assembling the elements of said clutch release bearing.
