Experimental Investigation of Self-Lubricating Sliding Bearings

Self-lubricating sliding bearings are widely used in numerous industrial applications, primary regarding their specific lubrication mechanism. This lubrication mechanism is a main advantage compared with classical sliding bearings, where their production is not so complicate and makes lower price. This kind of bearing could be simple to assembly and in operating produce less noise and vibrations. According to their material and type of operating, self-lubricating sliding bearings could operate with oil (grease) in its own material structure or even without any amount of lubricant. Besides numerical analysis and calculations, at Faculty of Mechanical Engineering, University of Belgrade numerous experimental investigations of those bearings have been conducted, regarding own laboratory with test rig. This paper presents only selected results of those experiments, where portable DAQ acquisition with LabVIEW software tool was applied.
