1. An assembly for an aircraft motor, comprising:
a bearing extending circumferentially around an axis;
a stationary structure circumscribing the bearing; and
a flexible support arranged radially between the bearing and the stationary structure, the flexible support including
an inner ring radially engaging an outer surface of the bearing;
an outer ring radially engaging the stationary structure;
a bridge projecting radially out from the inner ring to the outer ring, the bridge extending circumferentially about the inner ring;
an open first channel extending axially into the flexible support from a first side of the flexible support to the bridge; and
an open second channel extending axially into the flexible support from a second side of the flexible support to the bridge;
wherein a continuous annular groove projects radially into the outer ring towards the bridge, the groove extends axially within the outer ring, and the groove extends circumferentially about the axis within the outer ring; and
wherein the groove has an axial width that is greater than an axial thickness of the bridge.
