The hollow cylindrical bore has a journal bearing portion including first and second distal tapered bearing segments separated by a central bearing segment having a constant radius. Each of the first and second distal tapered bearing segments has a tapered bearing radius that increases with distance from the central bearing segment to a maximum tapered bearing radius that is in the range of 0.5 microns to 1.5 microns greater than the constant radius. Subsequently, a cylindrical spindle shaft is inserted into the hollow cylindrical bore. In an alternative embodiment, a cylindrical outer surface of the spindle shaft includes the tapered bearing segments, rather than the hollow cylindrical bore."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Disk drive spindle with fluid journal bearing having increased radial clearance in axial end regions","description":"A method to fabricate a fluid bearing spindle includes creating a hollow cylindrical bore through a solid workpiece.
