The Ribbon bearings that can reversibly rotate, which is one type of spiral-grooved thrust bearing, are supposed with an experimental verification in this paper. Liquid injection method is applied to the bearing to reduce the friction at start period. It means that the bearing is 'hybrid' one constructed by hydrostatic and hydrodynamic bearing. By circulating the lubricant in the clearance, temperature raise can be also controlled. Furthermore, to investigate a possibility ofa bearing that realizes rmch higher load carrying capacity, the effect of spiral groove depth to bearing characteristics is experimentally examined, resulting that the optirrum depth is about lOOμm.
