Abstract
A bearing support ring includes a plurality of contact pads radially protruding from inner and outer circumferential surfaces of the ring. Flexible portions of the ring are defined between the contact pads and have a radial thickness less than that of the ring at the contact pads, such as to permit elastic deflection of the ring in a radial direction between the contact pads. Openings sized to permit unrestricted oil flow are provided, such as within the flexible portions of the ring.
