The invention relates to a device comprising a fixed actuator for a control system (2) for the orientation of fan blades of a turbomachine, comprising : at least one actuator body (22) housed inside an annular casing (20) of the turbomachine forming a bearing support, the annular casing (20) being centred on a longitudinal axis (X-X) of the turbomachine an inclined relative thereto, the actuator body (22) having an internal volume in which a piston (30) is able to slide, separating the internal volume into two chambers (22a, 22b) isolated from one another; and a plurality of actuator rods (42) passing through the annular casing (20) forming a bearing support and each having one end fixed to the piston (30) and an opposite end intended to be connected to an internal ring (14) of a movement transfer bearing (10) in order to drive it in translation, the internal volume of the actuator body (22) being closed downstream by a chamber bottom (32) which forms a single part with the annular casing (20) forming a bearing support.
