GB/T 40116-2021 specifies the test methods for three core performance characteristics of foil gas dynamic radial bearings: static load capacity, friction coefficient, and service life. The standard defines detailed requirements for test conditions, loading procedures, data acquisition, and result calculations, providing unified experimental criteria for evaluating the performance of such bearings. The relevant tests must be conducted on a dedicated bearing test rig, which should be capable of precisely controlling rotational speed and radial load, and be equipped with high-precision force sensors, torque meters, and other devices to measure load and friction torque.
