    • Abstract
  • The paper proposed a gas film thickness distribution formula involved gas film thickness error, round and cylindrical errors. The effect of tolerance on the performance of an externally pressurized air journal bearing was studied by the finite element method. It is shown that round and cylindrical errors have less effect on the load-carrying capacity of the bearing, and an average film thickness error of 5% may result in a load-carrying change of 10%.
