Disclosed is a crane, in particular for offshore application. The crane includes a bearing the assembly between a pedestal and a carrier frame. The bearings are distributed over the height of the support structure and include upper bearing, which include a radial contact rolling bearing including rolling elements and a smooth cylindrical raceway, coaxial to the axis of rotation. The radial contact rolling bearing allows a longitudinal translational degree of freedom of the rolling elements over the height of the cylindrical raceway.
