What is ISO 13939 - Performance testing of foil journal bearings about?
ISO 13939 is an International Standard that discusses performance testing of foil bearings. It provides best practices to ensure stability and load capacity of foil journal bearings can be optimized.
ISO 13939 describes a method for comparing the performance test results of foil journal bearings, which are lubricated by air (gas) and supported by the gas-dynamic force generated via the rotations of the rotating shaft. The test method described in ISO 13939 has the following application coverage.
