The unit (1) has a metal frame (8) including a bearing (15) i.e. metal jacket, to define a longitudinal axis. A pin has a hollow cylindrical main shaft (53) mounted in translation and/or in rotation relative to the bearing. A coupling mechanism couples the shaft to a micromechanical mechanism. A torque sensor i.e. torque meter and/or force sensor, is coupled to the frame and the pin. An injection system injects pressurized fluid e.g. gas, to an interface between the bearing and the shaft. The bearing is provided with radial through-holes equidistant from front and rear faces of the bearing. |
