This paper presents a study on the characterization of lubrication films with various lubricant quantities. Experiments were conducted with an optical slider-bearing test rig. Under limited lubricant supply, there exists a critical speed beyond which the film thickness will no longer increase with increasing speeds due to starvation at the inlet. The critical speed depends significantly on the lubricant quantity, as well as lubricant viscosity and load. Comparison between experimental and calculated results indicated that the starvation area with fragmented films has certain loadcarrying capacity but very small viscous resistance. Friction does not show much deviation for different lubricant quantities.
