Equations relating the flow of the lubricant and the axial motion of an externally pressurized thrust bearing are developed. The bearing is shown to be stable when the fluid is incompressible.

Expressions for local stiffness and damping coefficients, useful in the evaluation of the dynamic response of the bearing, are given.

An analog computer solution of the equation of motion is compared with the results of the corresponding, small displacement equation.
