1. What is Maximum Limit Size of Hole?

Definition: Maximum limit size of hole is defined as the maximum diameter of hole possible for given fit.

Purpose: It helps engineers and designers determine the upper limit for hole size in clearance fits.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( H_{max} \) — Maximum limit size of hole (meters)
• \( C_{max} \) — Maximum clearance (meters)
• \( S_{min} \) — Minimum limit size of shaft (meters)

Explanation: The maximum hole size is calculated by adding the maximum clearance to the minimum shaft size.

3. Importance of Tolerance

Details: The tolerance percentage (±5% by default) accounts for manufacturing variations and ensures proper fit.

4. Using the Calculator

Tips: Enter the maximum clearance and minimum shaft size in meters, and specify tolerance percentage. All values must be ≥ 0.

5. Frequently Asked Questions (FAQ)

Q1: What is maximum clearance?
A: Maximum clearance is the maximum space available between a hole and a shaft or between two assembled parts.

Q2: What is minimum limit size of shaft?
A: Minimum limit size of shaft is the minimum diameter of shaft possible in clearance fit.

Q3: When would I adjust the tolerance?
A: Adjust tolerance based on manufacturing capabilities and required fit precision.

Q4: What units does this calculator use?
A: All calculations are performed in meters (m).

Q5: How precise should my inputs be?
A: For engineering applications, typically use 4 decimal places (0.0001 m precision).
