Pressure fed journal bearing

Cross-section or cutaway of a cylindrical pressure-fed plain journal bearing assembly, showing a smooth metallic journal shaft centered inside a circular bearing bushing or outer shell. A narrow annular lubrication clearance is visible between the shaft and inner bore as a thin oil film, highlighted as a fine ring. The bearing includes a distinct circumferential feed groove around the inner surface of the bore, with a small radial oil feed port entering the groove. The shaft is metallic gray steel, while the bushing or shell is metallic gray or bronze-toned, with a compact industrial appearance.
