Simple calculation of hydraulic cylinder thrust

・The formula for converting hydraulic cylinder output into approximate Power Cylinder thrust is provided below.
・This calculation formula is a rough outline and should be used as reference only. Please contact us for more detailed consideration.


・Enter the hydraulic cylinder specifications and press the Calculate button.

・Please use “.” for the decimal point and not “,” as the calculation error will occur.

Operating pressure P (Note 1): Mpa
Hydraulic efficiency (Note 2):

Calculate

Note 1
Please enter a value of 1Mpa or greater.

Note 2
Hydraulic efficiency is the ratio of the theoretical output of a hydraulic cylinder to the load actually applied to the cylinder.
The following values are recommended as a guide for hydraulic efficiency, but the final values should be determined and entered by the customer.
・Low speed operation (50 mm/sec or less): 0.5 to 0.8
- Medium speed operation (51 to 250 mm/sec): 0.35 to 0.5
High-speed operation (251 mm/sec or more): 0.25 to 0.35


・Calculation results of hydraulic cylinder output converted into approximate Power Cylinder thrust

Conversion thrust when pushing (FH) = × × × 10-3　= kN, kgf
Pull equivalent thrust (FR) = × × × 10-3　= kN, kgf

Advantages of replacing hydraulic cylinders with electric cylinders (Power Cylinder)

There are various benefits, such as improved cost performance through energy savings, easier maintenance, and improved cleanliness.

For details, please refer to the guide for replacing hydraulic systems.
