1. A rotating hydraulic machine comprising:
a casing,
a shaft rotatably mounted with respect to the casing,
a sleeve immobilized with respect to the shaft,
the sleeve being rigidly fixed to the shaft by a first end of the sleeve,
the sleeve having a second end extending around at least a portion of the casing,
a cam immobilized with respect to one among the casing and the shaft,
a cylinder block immobilized in rotation with respect to the other among the casing and the shaft,
the cylinder block comprising pistons configured to cooperate with the cam to generate a relative rotation between the shaft and the casing,
first and second guide bearings each directly in abutment against the casing and the sleeve,
the first and second guide bearings extending around the portion of the casing,
at least a third guide bearing directly in abutment against the casing and the cylinder block, and
a power take-off,
wherein the first and second guide bearings and the power take-off are located on opposite sides of the second end of the sleeve.
