Literal lookup table (piecewise if/else chain over the diameter selector), not a physics model — same nature as newway-porous-bearing-flat-round.ts but a disjoint diameter range (13–75 mm) and a disjoint field set (adds OD/L for the cylindrical bushing geometry, has no separate "Height" field, uses "Radial stiffness"/"max Load" labeling and a 4 µm fixed air gap vs the flat-round page’s 5 µm fixed fly height) — confirmed as a genuinely different product/model despite the identical <title> text in the legacy source.
