Inner diameter of the cylinder barrel (the full bore).

Diameter of the piston rod. Set to 0 for a rodless or ram cylinder.

Extend force: 1963.50 N

  • Extend (push) force is 1963.50 N. This is the force produced when pressure acts on the full bore face.
  • Retract (pull) force is 1472.62 N. The rod reduces the effective pressure area, so retract force is always lower than extend force for the same pressure.
  • The retract-to-extend ratio is 75.0%. A ratio well below 100% indicates a large rod relative to the bore.
  • Verify your pressure gauge reading is gauge pressure (relative to atmosphere), not absolute pressure.

Next stepAlways apply a safety factor of at least 1.25 to 1.5 to the calculated force or pressure before selecting a cylinder and seals.
