ABSTRACT:
A bearing arrangement for an articulatable support (6) comprises bearing assemblies (20/28, 22/29, 24/30and26/32). In one embodiment the assemblies comprise a ball (20, 22, 24, 26) and aperture (40FIG.2) having sliding contact at discrete areas (36) during relative rotation. In another embodiment the sliding contact may be formed at a ball (20,22,24,26) and a plastics e.g. P.T.F.E. support (84, 85FIGS.10and11). Resilient displacement of the bearing contact along a rotational axis (A and B) is provided by planar spring supports (28, 32) and rigid support is provided by supports (29and30).
