1. A bearing arrangement including:
a rolling element bearing assembly including a bearing cage having
a cage body having an inner surface defining a bore coaxially aligned with the principal rotational axis of the bearing cage,a plurality of pockets, each pocket housing a rotatable rolling element of the rolling element bearing assembly, the pockets being arranged sequentially around the cage body with respect to the principal rotational axis of the bearing cage, anda skirt projecting from the cage body in the axial direction; a first body located in the bore of the bearing cage and coaxially aligned with the principal rotational axis of the bearing cage, and arranged to engage each of the rolling elements; a second body arranged circumferentially around the bearing cage to engage the rolling elements, the first and second bodies being rotatable with respect to one another about the principal rotational axis of the bearing cage; and a bearing chamber arranged to house the rolling element bearing assembly, the bearing chamber providing a source of gas flow into the bearing chamber; wherein: the bearing cage includes a flow deflector projecting from the skirt in the radial direction which is arranged to intercept the gas flow between the source and the cage body so as to deflect the gas flow away from the cage body. |
