Abstract: This paper describes the static characteristics of a slot-entry gas journal bearing with feeding holes. Gas flow in this bearing is restricted first by inflow resistance when gas rapidly flows into the narrow gap of the slot region from isolated feeding holes, and then, restricted more by viscous resistance in the slot region. Therefore, the maximum load capacity and stiffness in this type of bearing can be easily obtained even in a very small bearing clearance of less than 10 μm because gas flow entering the journal can be restricted to a very small amount. Here, the static characteristics of this type of bearings are determined numerically by using the finite difference method. The validity of the theoretical predictions is confirmed by comparison with the experimental results.
