AVAILABLE FORCES 

 

Forces  developed  by  the  cylinders  are  determined  by  multiplying  the  applied  air  pressure  by 
the exposed piston area, less the spring force. 
 
 

Pounds of force = applied pressure (psi) x piston area minus 

 

 

 

   pounds of spring force. 

 
The accompanying graph shows pressure in psi required to overcome the force of the spring 
as the piston rod is retracted or extended from its center position.  Opposing spring force in-
creases as the stroke length of the piston rod increases and the spring is further compressed.  
From the graph, pounds of spring force can be determined by multiplying the pressure (psi) by 
the piston area.  Thus, the initial force of the cylinder at zero stroke in the center position is:

P -066824-01000 & R431004943 (P -059211-00000) 

 
 

Pounds of force (retracted stroke) = applied pressure (psi) x 2.2 inches (56 mm) 

 

 

 

 

 

      minus 18 psi x 2.4 inches (1.2 bar x 61 mm) 

 
 

Pounds of force (extended stroke) = applied pressure (psi) x 2.4 inches (61 mm) 

 

 

 

 

 

       minus 18 psi x 2.4 inches (1.2 bar x 61 mm) 

 
For spring force at subsequent piston rod positions on either retracted or extended stroke, pro-
ject across the graph from the appropriate stroke length point on the vertical line until the pres-
sure line is intersected.  Project down from this point to arrive at pressure in psi.  Multiply this 
figure by the 2.4 inches (61 mm) of piston area.
