Breakaway Pressures in PSI Breakaway Pressures An average of 5 pounds (psig) is necessary to breakaway non-cushioned Series A & J air cylinders when mounted horizontally with no load on the piston rod. Double rod end cylin- ders require an average of 7 pounds (psig). An average of 6 pounds (psig) is required to breakaway single rod and Series A, EA, J & EJ air cylinders equipped with optional non-adjustable air cushions. Double rod end cylinders require an average of 8 pounds (psig). These figures are for non-cushioned cylinders with strokes of 6 inches or less with factory lubrication. Consult John Henry Foster Co. if your application requires a lower breakaway pressure or a guaranteed minimum breakaway. Series A & J cylinders with 3-1/4" thru 12" diameter pistons are counterbored to provide a larger area for the pressure to act upon. Listed are the average breakaway pressures in PSI for all Series A, EA, J, & EJ Cylinders. If your application requires a lower breakaway pressure than indicated for a particular bore size, consult John Henry Foster Co.
