In a camshaft unit, particularly of an internal combustion engine, comprising a camshaft connected to a drive unit to be driven thereby, a phase displacement unit including an actuating gear and a control unit with a rotor and a stator unit in the form of a brake element for adjusting a phase relation between the drive unit and the camshaft, and a bearing device for supporting part of the control unit, the bearing device is designed to accommodate radial tolerances between the stator element and the rotor element.
