Zusammenfassung:	A bearing arrangement comprises a rolling element bearing assembly including a bearing cage. The bearing cage comprises an annular cage body having an inner surface defining a coaxial bore. The bearing cage has a plurality of circumferentially spaced pockets and each pocket houses a rotatable rolling element. A first annular skirt extends axially from a radially inner end of a first axial end of the cage body and at least one first support member extends radially and axially from the remote axial end of the first annular skirt to the radially outer end of annular cage body. The bearing cage is hollow and has a high stiffness to weight ratio. The bearing arrangement is particularly suitable for use for a planet gear of a planetary gearbox. The planetary gearbox may be for a gas turbine engine.
