A rotary planet carrier for a mechanical reduction gear of a turbomachine having an annular row of tubular members for supporting bearings that are parallel to one another and to an axis of rotation (X) of the planet carrier. The tubular members include grooves for oil to flow through that are connected to oil ducts that extend from the grooves to an external peripheral surface. The grooves are rectilinear and parallel to one another and to an axis of revolution (Y) of an internal cylindrical surface of a corresponding tubular member. Some of the grooves have a width about the axis of revolution that is greater than the diameter of the ducts connected to this groove. Some of the ducts are connected to the corresponding groove that is closest to the axis of rotation (X) of the planet carrier.
