Welcome to the Ram Power Hydraulic Calculator.

Our online calculator will privde you with all the measurements that we will require in order to progress making a hydraulic solution for you. Please enter as much information as you can in the required fields and the calculator will complete the rest. Please remember that there are a certain number of required fields in order for the process to work - these are marked *


1. What are the known measurements of the ram? [e.g you may know what that you want the bore to be 20mm and that you have a power unit that can run at 20bar]. Please enter as many of the fields as you can.

Variable Results/value Variable/value Results/value
BORE mm ROD mm
STROKE mm PRESSURE bar
FLOW lpm PIPE BORE mm
 
1. Choose the style of the hydraulic solution - see diagrams below


Rounded Mounting
Front Trunnion Mounted
Fixed Body, Guided Rod
Fixed Body, Free Rod

3. Calculate - Although many of the variable fields will produce immediately visual results we recommend that you click the 'calculate' button opposite to ensure that the system has considered all enterred values.

 

Below will return the results of other, required measurements that will need to be considered when the hydraulic solution is worked out. These variables will indicate whether an enterred value will result in a PASS or FAIL for a solution.

'Now that you have calculated the ram you may alter the Pull/Thrust figures in the fields below to adjust the requirement.'

4. How much force needs to be applied? [this is available for entry in kN, lbf or kgf]. You can enter either or both Thrust or Pull variables if they are known, or simply just one variable.

Variable Results/value Variable/value Results/value
THRUST kN   THRUST kgf          
THRUST lbf   PULL Kn  
PULL kgf   PULL lbf
