Bore diameter calculating according to the require force

Guide to using the above calculators:

• Table 1: From this table, you can calculate the output power of a pneumatic cylinder in a very simple way without need to use a formula. Just enter the inner diameter of your pneumatic cylinder along with the air pressure of your compressor so that the power of the pneumatic cylinder is accurately calculated and displayed for you.

As you know, the main factor for choosing a suitable pneumatic cylinder for your system is the inner diameter (Bore) of the cylinder. Because this diameter is the component of the cross section of the cylinder and the part where the piston moves.

The next determining factor is the air pressure of the air compressor, which has a direct relationship with the output power of the pneumatic cylinder. Naturally, the higher the wind pressure, the greater the power of the cylinder.

• The second table: If you know the required force of your system, but you don’t know the suitable diameter of the pneumatic cylinder, you should use this table to automatically calculate the minimum diameter of the pneumatic cylinder for you. In fact, with this number, you can choose and buy the cylinder you need.

Pneumatic cylinder force table

If you need a pneumatic cylinder force table, you can use the photo below and see different cylinder diameters at different pressures in a classified manner. This table contains information such as force in open or closed cylinder courses, which are all calculated in SI units.

pneumatic cylinder force formula

Using the above formula, you can calculate the power of a pneumatic cylinder in the open state.

F= power in kg – force P = air pressure of the compressor in Bar A = cross-sectional area of ​​the cylinder in square centimeters

Calculate the power of the pneumatic cylinder in the closed state

Maybe the question arises whether the power of a pneumatic cylinder is different when it is open or closed? In answer to this question, let’s say yes!! The power of the pneumatic cylinder in the closed state is less than the open state, and that is due to the presence of the shaft and the reduced cross-sectional area. Pay attention to the following photo:

One of the important factors in calculating the power of a pneumatic cylinder is the cross-sectional area, the larger the cross-sectional area, the greater the cylinder’s productive power. In the closed position, the air force of the compressor enters the side of the cylinder where the shaft is. Therefore, the diameter of the shaft has reduced a part of the cross section. So, in the calculation to close the cylinder, we should subtract the diameter of the pneumatic cylinder shaft from the cross section and then multiply it by the pressure to get the real power.

The effect of friction on the force of a pneumatic jack

The presence of friction cannot be ignored anywhere. So we also have to subtract the friction force from the cylinder force in our calculations. From the table below, you can see how much friction should be deducted in different situations:

Final conclusion

According to the given explanations, you can easily measure the force of a pneumatic cylinder or the diameter of the cylinder you need according to the required data, so that you can easily choose the pneumatic cylinder that suits your needs.
