1. What is a Hydraulic Cylinder Load Calculator?

Definition: This calculator determines the force generated by a hydraulic cylinder based on system pressure and piston area.

Purpose: It helps engineers and technicians calculate the load capacity of hydraulic systems for design and troubleshooting.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( F \) — Force (pounds)
• \( P \) — Pressure (pounds per square inch, psi)
• \( A_c \) — Cylinder area (square inches, in²)

Explanation: The hydraulic pressure multiplied by the piston's effective area equals the output force.

3. Importance of Hydraulic Load Calculation

Details: Accurate force calculation ensures proper system design, component selection, and safety in hydraulic applications.

4. Using the Calculator

Tips: Enter the system pressure in psi and the cylinder's effective area in square inches. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I find the cylinder area?
A: For a single-acting cylinder, use: \( A = \pi \times r^2 \) where r is the piston radius.

Q2: Does this account for friction losses?
A: No, this calculates theoretical force. Actual force may be 5-10% less due to friction.

Q3: What's typical hydraulic system pressure?
A: Common industrial systems operate at 1500-3000 psi, but always check your specific system.

Q4: How does rod area affect calculations?
A: For retraction force on double-acting cylinders, subtract rod area from piston area.

Q5: Can I use this for pneumatic cylinders?
A: Yes, the same formula applies, but pneumatic systems typically operate at much lower pressures (80-150 psi).
