An axially compliant rolling bearing for precision motion stages having a stage, at least one bearing member slidably disposed along a rail, and a compliant joint interconnecting the at least one roller bearing to the stage. The compliant joint is sufficiently compliant to permit movement of the stage in the axial direction while remaining stiff in other directions orthogonal to the axial direction.
