The structure of an eccentric short roller bearing is denoted, methods are given for determining the bearing clearance, its eccentricity and its lift estimate, by which a double row eccentric short roller bearing is designed and manufactured.

Taking consideration of the existence of manufacturing errors of aerostatic journal bearing, the paper deals with the calculation and theoretical analysis of the static characteristics of aerostatic journal bearing with orifices by Galerkin Finite Element Method (FEM).
