• In this study we investigate the impulse performance of self-acting semi-spherical air bearings. Parameters affecting the performance of the air bearing are the clearance between the rotor and stator and stator groove depth. Rotation speed is changed from 13 000 rpm to 23 000 rpm. Rotor impulse displacement, impulse stiffness and allowable impulse are selected as axial impulse performance factors. Experimental results show that rotor impulse displacement and impulse stiffness decrease when the speed as well as the groove depth increase and the clearance decreases. Allowable impulse does not change significantly with changes in the clearance, and has a maximum value at a certain groove depth.
