The correct answer is: Shrink Fit – a type of Interference Fit 🔥❄️ In this method, one part is frozen (usually the shaft) and the other is heated (usually the hub). Once assembled, they lock tightly as they return to room temperature — no bolts, no welding, just pure mechanical grip! 🔩 Shrink Fit = Interference Fit done thermally ✅ Used in gears, pulleys, bearings, rotors, and shafts ✅ Delivers high-torque transmission without slippage ✅ Ideal for precision fits, dynamic loads, and permanent j
