Selecting the Proper Size Cylinder
Determine The Force Required -- To select a cylinder for an application, first determine the maximum push and/or pull force required to do the job. Then use the pressure table to select the cylinder that gives the necessary force for your application. It should be noted that the force requirements derived by formula are only theoretically correct. Other factors must be provided for. Pressure drop -- which means that working pressure at the cylinder port will be somewhat less than system pressure -- should be allowed for in such calculations. A margin for overcoming friction in the cylinder likewise must be added. After selecting the proper size cylinder for the job use envelope and mounting dimension charts to determine cylinder dimensions.
