Abstract
A bearing assembly (2) comprises an outer shell (3) providing a pair of coaxial annular surfaces (4a, 5a) spaced apart-and facing inwardly towards each other, and an inner shell (7) within the outer shell, the inner shell providing a pair of coaxial annular surfaces (8a, 9a), each of which faces outwardly towards one of the inwardly-facing annular surfaces of the outer shell and is arranged substantially coaxially with, and adjacent to, its associated inwardly-facing annular surface. The inner shell (7) is capable of movement relative to the outer shell (3) in an axial direction and by inclination to the outer shell. Each of the said inwardly-facing annular surfaces (4a, 5a) and/or its associated outwardly-facing annular surface (8a, 9a) has one or more channels (13, 14) arranged to extend around the surface. The bearing assembly (2) also comprises means (17-21) for supplying a fluid from a high pressure source to each of the said channels (13, 14) through flow resistance means (15, 16).
