Abstract:
1. An annular bearing arrangement configured for providing free rotation between two coaxially aligned bodies between which the bearing arrangement is coaxially aligned, the bearing arrangement including: a bearing chamber having a gas inlet and a lubricant inlet and arranged to house a rolling element bearing assembly, the rolling element bearing assembly including a bearing cage having a cage body close to or in axial alignment with the gas inlet and 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, and a skirt projecting from the cage body in the axial direction and past the lubricant inlet, wherein: the bearing cage includes a flow deflector projecting from the skirt in the radial direction at an axial position which is between the lubricant inlet and the gas inlet and which is arranged to intercept gas flow entering by the gas inlet so as to deflect the gas flow away from the cage body.
