Metric O-Ring Size Calculation:
| From: | To: |
Metric O-Ring Size Calculation determines the total length of an O-ring based on its mean diameter and cross-sectional thickness. This measurement is essential for proper sealing applications in various industries.
The calculator uses the following formula:
Where:
Explanation: The formula calculates the total length by finding the circumference of the mean diameter and adding twice the cross-sectional thickness to account for the material's thickness on both sides.
Details: Accurate O-ring sizing is crucial for creating effective seals in hydraulic systems, pneumatic systems, and various mechanical applications. Proper sizing ensures optimal performance and prevents leaks.
Tips: Enter the mean diameter and cross section in millimeters. Both values must be positive numbers. The calculator will provide the total O-ring size in millimeters.
Q1: What is the difference between mean diameter and inner diameter?
A: Mean diameter is the average of the inner and outer diameters, while inner diameter refers only to the inside measurement of the O-ring.
Q2: Why is the cross section multiplied by 2 in the formula?
A: The cross section is multiplied by 2 to account for the material thickness on both sides of the mean diameter circumference.
Q3: Can this calculator be used for imperial measurements?
A: This calculator is designed for metric measurements. For imperial units, convert measurements to millimeters first or use a dedicated imperial calculator.
Q4: How accurate is this calculation for real-world applications?
A: While this calculation provides a theoretical size, actual O-ring selection should consider material properties, compression requirements, and specific application conditions.
Q5: What tolerance should I consider for O-ring sizes?
A: Standard O-ring tolerances are typically ±1-2% of the calculated size, but specific applications may require tighter tolerances.
