Pneumatic Cylinders Developing Specifications z Calculating the Proper Bore Size A cylinder’s bore size determines the force it will produce at a given supply pressure. The weight of the load or the clamping force required will largely determine the force requirements of the cylinder, and hence, the bore size required. But before determining the appropriate bore size you must compensate for air pressure drop, packing friction and load variations using the following computation: A) ompensating for Pressure Drop – Decrease the line pressure value C by 15 p.s.i. This compensates for pressure drop...

Z Rod Diameter A) Use the stroke factor table to find the proper multiplier based on the mounting configuration and rod end connection used. B) Multiply your required working stroke length by the factor you found from the stroke factor table in Step A. Note: if you require a rod or thread extension in your application (Longer than standard) add the extra length(s) to your required working stroke length and then multiply by the stroke factor found in Step A, the result of this arithmetic is the "L" Value. C) Use the piston rod diameter/ stop length chart to complete your cylinder specification. Find...
