The invention relates to treatment equipment, including a beam, for a paper machine. The beam () is equipped with a shaft (), which has a bearing assembly () adapted to allow the beam () to pivot in relation to the bearing assembly () as well as move in the axial direction. The treatment equipment () further comprises a support device () and an oscillator (). The support device () comprises a swing arm () and an actuator () connected thereto. In connection with the bearing assembly () there is an auxiliary arm (), which is adapted free in the radial direction and locked in the axial direction in relation to the bearing assembly (). In addition, there is a connection () between the swing arm () and the auxiliary arm (), allowing the swing arm () to move in the axial direction in relation to the auxiliary arm () without a radial distortion of the swing arm (). The invention also relates to similar treatment equipment without an actuator.
