Zusammenfassung:	A bearing damper includes: (a) an annular sleeve (42) having spaced-apart grooves (44, 46) formed in a radially-facing surface therein; (b) an annular bearing race (24) received in the sleeve (42); and (c) a resilient seal ring (54, 154) disposed in each of the grooves (44, 46), wherein the seal rings (54, 154) cooperate with the sleeve (42) and a radially-facing surface of the bearing race (24) to define a closed annular gap, and further wherein the seal rings (54, 154) are sized so as to urge the bearing race (24) towards a coaxial position relative to the sleeve (42).
