The result? Misaligned shafts, excess friction, and a full recall. Enter — the shorthand of the engineering world

So next time you type into a title block, know that you are speaking a precise, efficient, and globally understood language — one that has quietly held the mechanical world together for decades. Want to dive deeper? The official standard is ISO 2768‑1:1989 (linear) and ISO 2768‑2:1989 (geometric). Check with your national standards body for the latest editions.
