In this paper, the design formulas of the hydrostatic bearing are analyzed. The calculation errors of the hydrostatic bearing with wide and narrow seal oil-edge structures under large eccentricity and the comparison with the numerical solution of the Reynolds equation are analyzed. The effective bearing area of the cavity is a theoretical basis of a variable; and the conclusion is drawn that the existing formula is used to calculate the design and calculation of a wide seal oil-edge bearing which is not suitable for the large eccentricity due to the large error; Dimensionless numerical calculation of the value of the bearing design of the chart and the error correction formula for the current formula, so that the design parameters of hydrostatic support can be more reasonable choice, designed to be more complete.
