In mechanical design, choosing the right basis for fits can simplify manufacturing and improve assembly efficiency.
Here's the difference:
🔹 Hole Basis System – The hole size stays constant, and the shaft size is varied to achieve the desired fit (clearance, transition, or interference). Most commonly used, especially with standard tooling like drills and reamers.
🔹 Shaft Basis System – The shaft size stays constant, and the hole size is adjusted. Useful when working with standard shafts (like motor shafts) or when the shaft cannot be altered.
Understanding these systems helps you ensure proper function and manufacturability of mechanical assemblies.
