A support for a bearing comprises a resilient ring having unevenly spaced inner (42) and outer (43) bumpers. The unevenly spaced bumpers (42, 43) provide anisotropy to the rotor (21) to preclude non-synchronous vibration. The inner bumpers (42) can be ground to provide a vertical offset of the rotor centerline to accommodate the deflection due to the rotor weight. A tangential groove (46) its the outer bumper (43) allows oil passage during ring deflection so that oil can be squeezed out under dynamic load, providing additional viscous damping to the rotor (21).
