1. What is Bore Diameter Calculation?

The bore diameter calculation determines the required cylinder size to produce a specific force at a given hydraulic pressure. It's essential for hydraulic system design and component selection.

2. How Does the Calculator Work?

The calculator uses the bore diameter formula:

Where:

• \( \text{Force} \) — Desired output force in pounds (lbs)
• \( \text{PSI} \) — System pressure in pounds per square inch (psi)
• \( \pi \) — Mathematical constant Pi (~3.1416)

Explanation: The formula calculates the minimum cylinder diameter needed to generate the specified force at the given hydraulic pressure.

3. Importance of Bore Diameter

Details: Proper bore sizing ensures hydraulic cylinders can produce required forces without exceeding system pressure limits, affecting system efficiency and component longevity.

4. Using the Calculator

Tips: Enter force in pounds and system pressure in psi. Both values must be positive numbers. The result is the minimum bore diameter in inches.

5. Frequently Asked Questions (FAQ)

Q1: What's the relationship between bore size and force?
A: Force increases with the square of bore diameter - doubling bore size quadruples potential force at same pressure.

Q2: How does pressure affect bore size?
A: Higher system pressures allow smaller bore cylinders to achieve the same force, but require stronger components.

Q3: What are typical bore sizes?
A: Standard hydraulic cylinders range from 1.5" to 24" bore, with 2.5", 3.5", 4", 5" being common sizes.

Q4: Should I round up the calculated bore size?
A: Yes, always select the next available standard bore size equal to or larger than your calculation.

Q5: Does rod size affect this calculation?
A: Rod size affects retraction force but not extension force. This calculation is for extension (push) force only.
