A new analytical method is proposed to calculate the static performance of hydrostatic journal bearing. Analytical expressions of recess pressure and flow are deduced through analyzing flow continuity equation and utilizing Gauss–Legendre integral formula. To study the computational accuracy and the application range of the new method, recess pressure and flow of a four-pocket capillary compensated hydrostatic bearing under different eccentricity ratios and wrap angles of oil recess are calculated using three methods (the new method, the old analytical method and the finite difference method). The results indicate that new analytical method has the advantage of simplicity and high computational accuracy.
