Tonnage @ 90 PSI:Our cylinders are based on a standard shop air supply pressure of 90 PSI. The force given is for reference, all of our cylinders will run in a range of 60-120 PSI safely. See our support section for more recommendations.

Ratio: Use this to figure out your output force with different air pressures.
(Output force) lbs = Ratio x (Air Pressure PSI)

Total stroke: is the total amount the the output rod can extend with the power stroke active.

Power stroke: is the length of stoke that the full force acts on. The power stroke can be engaged at any point in the total stroke until it is used up. A unique feature of our cylinder is the power stroke can be cycled multiple times until you run out of total stroke.
