Claim 10:
11. A bearing component, comprising:
an external cylindrical member having an outer bearing surface and an inner cavity;
an internal cylindrical member, arranged in the inner cavity of the external cylindrical member and substantially coaxial thereto,
wherein the external cylindrical member and the internal cylindrical member form a gap therebetween,
wherein a resilient damping feature is arranged in the gap,
wherein the resilient damping feature includes a corrugated tubular sheet arranged in the gap between the external cylindrical member and the internal cylindrical member,
wherein the corrugated tubular sheet comprises corrugations extending parallel to an axis of the external cylindrical member and of the internal cylindrical member, and
wherein the inner cavity of the external cylindrical member has first radial projections extending inwardly from a surface of the inner cavity towards the corrugated tubular sheet, the internal cylindrical member has second radial projections extending outwardly towards the external cylindrical member, and the first radial projections and the second radial projections co-act with the corrugations of the corrugated tubular sheet to limit angular displacement of the external cylindrical member with respect to the internal cylindrical member.
