Spherical squeeze-film hybrid bearings were analyzed theoretically. Based on an asymptotic approximation for large squeeze number, the solution of the Reynolds’ equation applicable to the system under investigation was obtained. Perturbation method has been used; the results are valid for small radial displacement only. It has no limitation, however, in the values of compressibility number, axial displacement ratio, and excursion ratio. Numerical calculations have been programmed on the GE205 computer. Axial load capacity, axial stiffness, and radial and tangential stiffnesses were obtained.
