Pneumatic Cylinder Force Formula:
From: | To: |
Definition: This calculator determines the force exerted by a pneumatic cylinder in kilogram-force (kgf) based on air pressure, cylinder diameter, and gravity.
Purpose: It helps engineers and technicians properly size pneumatic cylinders for industrial applications.
The calculator uses the formula:
Where:
Explanation: The formula calculates the piston area, multiplies by pressure to get force in Newtons, then converts to kgf by dividing by gravity.
Details: Accurate force calculation ensures proper cylinder selection for applications like clamping, lifting, and pressing operations.
Tips: Enter the air pressure in Pascals, cylinder diameter in meters, and gravity (default 9.81 m/s²). All values must be > 0.
Q1: Why convert from Newtons to kgf?
A: Kilogram-force is a more intuitive unit for many mechanical applications, especially in countries using the metric system.
Q2: What's a typical operating pressure?
A: Most pneumatic systems operate between 400,000-700,000 Pa (4-7 bar), but check your specific system requirements.
Q3: Does this calculate extending or retracting force?
A: This calculates extending force. For retracting force, use the piston rod diameter in the calculation.
Q4: How do I convert bar to Pascals?
A: 1 bar = 100,000 Pa. Multiply bar value by 100,000 before entering.
Q5: Does this account for friction losses?
A: No, this is theoretical force. Actual force may be 10-20% less due to friction and efficiency losses.
