A bearing assembly (10) comprising relatively rotatable structures (12, 14) and a bearing (16), the bearing (16) is configured to work in operative association with the relatively rotatable structures (12, 14) to enable relative rotation therebetween, the relatively rotatable structures (12, 14) co-operate to define a bearing chamber (34), wherein the bearing chamber (34) is further defined by means to vary the volume (20) of the bearing chamber (34) between a first volume and a second volume, the second volume being greater than the first volume. |
