A bearing for a turbine engine includes an oil film compression damper, including an inner sleeve intended to receive an outer ring of a roller bearing, an outer sleeve surrounding the inner sleeve and delimiting with this inner sleeve, an axisymmetric cavity supplied hydraulically in order to form a film of damping oil, this cavity being closed at its ends by two segments. The cavity includes a first portion and a second portion separated from one another by a movable segment able to occupy a closed position in which it forms a controlled sealing barrier between the two portions, and an open position in which the two portions communicate with one another, and in that it is the first portion that is supplied hydraulically to form the film of oil.
