A turbofan engine comprising: an engine case; a gaspath through the engine case; a fan having a circumferential array of fan blades; a fan case encircling the fan blades radially outboard of the engine case; a plurality of fan case vanes extending outward from the engine case to the fan case; a front frame assembly comprising a plurality of vanes extending radially across the gas path; a shaft; a transmission coupling the shaft to a fan shaft to drive the fan; a bearing assembly (602; 702; 802) coupling the shaft to the front frame assembly; and a bearing support extending aftward and radially inward from the front frame assembly to the bearing assembly; characterised in that: the bearing assembly is a duplex bearing, which comprises a forward bearing and an aft bearing; wherein the forward bearing has a center spaced apart from a center of the aft bearing by a bearing distance; and the forward bearing has an inboard race longitudinally cantilevered by a cantilever distance at least about 20% of said bearing distance; and/or the forward bearing has an outboard race longitudinally cantilevered by a cantilever distance at least about 20% of said bearing distance;and/or an inboard support at a center of the bearing distance is longitudinally cantilevered by a cantilever distance at least about 10% of said bearing distance an engine case; a gaspath through the engine case; a fan having a circumferential array of fan blades; a fan case encircling the fan blades radially outboard of the engine case; a plurality of fan case vanes extending outward from the engine case to the fan case; a front frame assembly comprising a plurality of vanes extending radially across the gas path; a shaft; a transmission coupling the shaft to a fan shaft to drive the fan; a bearing assembly (602; 702; 802) coupling the shaft to the front frame assembly; and a bearing support extending aftward and radially inward from the front frame assembly to the bearing assembly; characterised in that: the bearing assembly is a duplex bearing, which comprises a forward bearing and an aft bearing; wherein the forward bearing has a center spaced apart from a center of the aft bearing by a bearing distance; and the forward bearing has an inboard race longitudinally cantilevered by a cantilever distance at least about 20% of said bearing distance; and/or the forward bearing has an outboard race longitudinally cantilevered by a cantilever distance at least about 20% of said bearing distance;and/or an inboard support at a center of the bearing distance is longitudinally cantilevered by a cantilever distance at least about 10% of said bearing distance the bearing assembly is a duplex bearing, which comprises a forward bearing and an aft bearing; wherein the forward bearing has a center spaced apart from a center of the aft bearing by a bearing distance; and the forward bearing has an inboard race longitudinally cantilevered by a cantilever distance at least about 20% of said bearing distance; and/or the forward bearing has an outboard race longitudinally cantilevered by a cantilever distance at least about 20% of said bearing distance;and/or an inboard support at a center of the bearing distance is longitudinally cantilevered by a cantilever distance at least about 10% of said bearing distance
