1. The result shows that the membrane-type restrictor has greater static stiffness than traditional ones (i.e. capillary) not only for single-pad cases but also for symmetric-pad configurations. 2. It is recommend to choice K~*_(r1)=K~*_(r2)=1.33 and λ=0.25 for the membrane restrictor in a symmetric-pad bearing for light-load design. 3. The minimal deviation of the bearing clearance will appear when K~*_(r1)=K~*_(r2)=1.33 and λ=1.0 (i. e. R_(ri) - R_o). The combination of the design parameters is recommend for heavy-load design. 4. The membrane restrictor will perform as a capillary restrictor when the stiffness of the membrane K~*_r > 5.0 5. It is similar to the single-pad case that the static stiffness of the opposed-pad bearing is inversely proportional to the nominal clearance of the bearing. The thinner nominal clearance is, the greater the stiffness and the smaller the power losses will be. (greater manufacturing accuracy will be required) 6. The bearing clearance will be maintained in most application range without any negative stiffness phenomena when both design parameter are properly chosen.
