A bearing structure having an annular cage and an annular housing that optionally mate at frustogeometrical surfaces for supporting and positioning a rotatable shaft of a turbomachine and that optionally provides a squeeze film damper between the frustogeometrical surfaces of the annular cage and the annular housing. A bearing structure having an annular cage and an annular housing that optionally mate at frustogeometrical surfaces for supporting and positioning a rotatable shaft of a turbomachine and that optionally provides an externally adjustable squeeze film damper between the frustogeometrical surfaces of the annular cage and the annular housing. The squeeze film damper is defined by two annular squeeze film seals positioned in respective annular squeeze film seal grooves formed in the frustogeometrical radially outer surface of the annular cage. Lubricant is also delivered to the squeeze film damper which serves as the damping medium.
