        "note": "Heat the hub (or chill the shaft) so it expands past the interference plus a little assembly clearance, then it slides on freely and grips as it returns to temperature: ΔT = (interference + clearance) ÷ (α · diameter). Steel α ≈ 11.7×10⁻⁶/K. Heating the hub is usual (an oven or induction); chilling the shaft with dry ice or liquid nitrogen suits delicate or already-assembled parts. Mind material temper limits when heating.",
