Annular bearing assembly for in a mast crane, comprising a lower (1101) and an upper (1102) ring. The upper ring comprises a first upper ring part and a second upper ring part. Rollers (1110) are arranged to carry the vertical downward forces, which are envisaged to be the vast majority of the forces exerted on the assembly. The rollers are arranged in a circumferential series in a circumferential series of cages. There is further a first slide pad (1113) which is absorbs vertical upward forces, but these are considerably less than those carried by the roller. The assembly further comprises a second (1111) and a third slide pad (1112), which are subjected to horizontal forces. The arrangement of lower ring and upper ring, with the one cage and three slide pads in transverse cross-sectional view, results in an improved distribution of the forces among the components of the bearing assembly.
