Inside cylinder bore / piston diameter.
mm
Rod diameter. Retract force uses piston area minus rod area.
mm
Working air pressure. 0.6 MPa is 6 bar, about 87 psi.
bar
Allowance for seal friction and losses. Use 100 for theoretical force.

1.06 kN · 238.4 lbf

Extend stroke uses full piston area.

Also computed

Extend force (F_ext) 1,060 N

1.06 kN · 238.4 lbf

Full piston area.

Retract force (F_ret) 890.6 N

0.8906 kN · 200.2 lbf

Piston area minus rod area.

Equivalent mass (F/g) 108.1 kg

Static vertical mass equivalent before application safety factors.

Piston area (A_p) 1,963 mm²

Annulus area (A_a) 1,649 mm²

Method notes 2 notes
  • Force uses gauge pressure times effective area, then multiplies by the entered efficiency allowance.
  • Real pneumatic sizing also needs speed, valve flow, pressure drop, cushioning, side load, friction, load orientation and a safety factor.
