Let rsquo; s use hydraulic-greener size as an example. A 1.0-in.-diam. Bore in that cylinder has 0.785 in.2 of Surface Area.Surface Area in the BORE, which is 300% more area than the 1-in. Bore. If the hydraulic presure being userd was 1000 PSI, the overals force would also, 300%,

　　diam. To a 0.100-I-DIAM. Gate has an increase of at Least 250% in POTENTIAL VOLUME MOLDED CASE Parts and Force.
