This invention refers to a hydraulic bearing clutch which is placed between the engine and the gear box, being suitable for any type of gear box. The hydraulic bearing clutch, according to this invention includes: a metal disc (1) coupled with an engine flywheel (2), a PTO shaft (3) attached to the metal disc (1) and tied in with a rotor (8) of the hydraulic pump (4) and a pressure chamber (7) mounted on the PTO shaft (3). Inside the hydraulic pump (4) there is a ball drum (9) tied in with the rotor (8) of the pump and in gear, through blocking, with the stator (15) of the pump. The stator is tied in with the primary shaft (6) on which are mounted a low pressure chamber (33) and a high pressure chamber (28). The high pressure chamber (28) is connected to a pressure regulator (38) and, through a solenoid valve (37), to the pressure chamber (7) on the PTO shaft (3). The pump rotor (8) has provided some radial rectangular seats (29) into which slide some metal blades (14), connected with an axial groove (11) and a radial groove (10) which correspond to the pressure chamber (7) on the PTO shaft (3). The axial groove (11) corresponds to a circular groove (17) and to the radial grooves (18) on the drum (9) and some balls (20) press on a circular groove (21) with bulges on the stator (15). The stator (15) is provided with admission ports (23), corresponding to the cross grooves (25) and the radial grooves (26), but also to the axial grooves (27) on the primary shaft (6). These grooves also make the connection with the high pressure chamber (28) and the low pressure chamber (33).
