40 mm Pneumatic Cylinder: Force Chart and Air Consumption

A 40 mm bore pneumatic cylinder (≈ 1.57 in) has a Ø16 mm rod and, per the Fenitsa catalogue, pushes 75 kg and pulls 63 kg at 6 bar (87 psi). Its piston area is 12.6 cm².

Typical uses: packaging machines, marking and light punching, part feeders. Standard strokes 50–500 mm; any stroke on request up to 3,000 mm for Ø40.

Series and Mountings in This Bore

FMY (ISO 15552, magnetic piston, adjustable cushioning), PAG-PAGY (CETOP RP 43P, aluminium body) and PNS-PNSY (CETOP RP 43P, steel body); every series also as double rod (C), tandem (T) and two-position (D). Mountings: clevis, flange, foot, trunnion, rod-end clevis and spherical eye.

Application Example

To move a 30 kg load at a 50 % load ratio (usual for moving loads), a Ø40 cylinder needs about 4.7 bar (68 psi).

Frequently Asked Questions

How much force does a 40 mm pneumatic cylinder produce?

Per the catalogue, 75 kg push and 63 kg pull at 6 bar; at 10 bar the theoretical push is 128 kgf (283 lbf).

What rod size does a 40 mm cylinder have?

Ø16 mm (0.63 in).

How much air does a 40 mm cylinder use?

About 1.6 litres of free air per double stroke for a 100 mm stroke at 6 bar.

What load can a Ø40 cylinder move at 6 bar?

About 40 kg as a moving load at a 50 % load ratio; for static clamping up to the catalogue 75 kg.
