SIZING
Rod selection chart: Table “1” Table “2”
Choice of piston rod size:
To choose the correct size of a piston rod for use in definite thrust conditions, proceed as follows:
1. Determine the type of fixing and end of the piston
rod to be used. Then, by referring to the relative table ”1”, ascertain the stroke factor “FC” corresponding to the application requested.
2. Using the correct stroke factor as derived from table
“1”, find the “ideal length” according to equation: “ideal length = actual length x stroke factor” 3. Calcolate the load in thrust condition for the
application, by multiplying the total section of the cylinder by the working pressure existing in the plant.
4. Using the diagram shown on the side (table “2”),
trace the point of intersection between the values of “ideal length” and “thrust”, which have been found by using the previous points 2 and 3.
The correct section of the piston rod can be obtained from the curved line indicated as “piston rod” diameter, above the point of intersection.

Base formulas:
Piston rod motion speed during excursion: V1= 10xQ (m/sec) A1x60 Motion speed during retraction: V2= 10xQ (m/sec) A2x60 Force applied in thrust condition: F= (P1xA1-P2xA2)x100 (daN) Force applied in traction condition: F= (P2xA2-P1xA1)x100 (daN) Where: A1= 3.14x(DxD) (cm²) A2= 3.14x(DxD-dxd) (cm²) 4x100 4x100 Magnitudes: P= Pressure (bar) A= Section (cm²) D= Piston diameter (mm) d= Piston rod diameter (mm) Q= Flow rate (l/min) V=Speed (m/sec) F= Force (daN) * * Where force = force of inertia: Fi= m x a; Force of work= Fl; Force of friction = Fa.
Notes: Sizing valid for cylinders series SCI / SCD
Trends of pressure in the braking chamber for progressive release brakes compared with step brakes, now disused. End-of-stroke brakings are recommended at speeds over 0.1m/sec and for applications with vertical loads.
This formula is fruit of the processing of experimental results. It does not have an absolute validity and deviations between practical results and theoretical conditions are always possible..
