A bearing isolator having an outer metal mounting ring adapted for attachment to a mounting structure, an inner metal mounting ring, adapted for registration on the outer race of a bearing for journalling a shaft and an energy-absorbing ring of composite material radially intermediate the metal rings. A first plurality of relatively short spokes extends between the composite ring and the outer metal ring; and, a second plurality of relatively short spokes extends between the composite ring and the inner metal ring and is circumferentially staggered from the first plurality of spokes. Resilient wave-like radial deflection of the composite ring occurs between the spokes to absorb vibration and acoustic energy. |
