A centering device for the guided transfer of bars from a feeder to a lathe, and interposed therebetween aligned with a bar guide with the mandrel of the lathe, comprising: a bush for fixing to a fixing seat and rigidly coupled to a bar opening aligned with the respective bar guide and with the mandrel of the lathe; a tubular body, rigidly coupled to the bush coaxial thereto and provided with a housing seat for a ring with oscillating elements which are pivoted to a respective fixed anchoring element with one end and are retained in mutual contact by elastic elements, delimiting a through opening whose diameter is about as long as the diameter of a bar. The ring and the anchoring element are axially movable within the seat, in contrast to springs toward the lathe.
