Measurement of non used microbearing grooved surfaces for computer ventilator Xilence Case Fan

In this paper is presented the measurement analysis of two a new non-damaged cooperating microbearing surfaces occurring in computer ventilator Xilence Case Fan 92mm. Elaborated measurements concern Scanning Electron Microscope (SEM) images of journal and sleeve work surfaces, AFM roughness tests with 3D images of journal and sleeve work surfaces and profiles of their cross sections, Vickers micro-hardness value studies for journal and sleeve surface. Furthermore in researches of the sleeve surface are included measurements for macro-profile surfaces with herringbone grooves micro-profiles of small grooves utilizing and Atomic Force Microscope) AFM - NT-206 Belarus. The measurements are performed for a new non damaged journal and sleeve surface using the AFM and SEM & Micro-X-Ray analysis. Such analysis concerns results referring to the bearing material composition with standard deviation of measured values. The view of cylindrical microbearing journal surfaces with nano-ridges and grooves and measured non used and non damaged surfaces with longitudinal nano-ridges and grooves in cylindrical slide microbearing journal and sleeve; SEM image of work surface of the microbearing journal and microbearing sleeve of computer ventilator Xilence Case Fan, 3D AFM image of work surface of microbearing journal, profile of work surface of the journal, 3D AFM image of work surface of microbearing sleeve of computer ventilator, profile of work surface of the sleeve are presented in the paper
