العربية40 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.
Force Chart by Pressure
Theoretical values; catalogue 6 bar figures allow for friction.
| Pressure | Push (N) | Push (kgf) | Push (lbf) | Pull (kgf) |
|---|---|---|---|---|
| 4 bar (58 psi) | 503 | 51 | 113 | 43 |
| 6 bar (87 psi) | 754 | 77 | 170 | 65 |
| 8 bar (116 psi) | 1,005 | 103 | 226 | 86 |
| 10 bar (145 psi) | 1,257 | 128 | 283 | 108 |
Catalogue at 6 bar: push 75 kg, pull 63 kg.
Air Consumption (6 bar, double stroke)
Free air in litres.
| Stroke (mm) | Air (L) |
|---|---|
| 50 | 0.8 |
| 100 | 1.6 |
| 200 | 3.2 |
| 300 | 4.8 |
| 500 | 8.0 |
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).
Compared with Neighbouring Bores
| Bore | Rod | Push 6 bar (kg) | Pull 6 bar (kg) |
|---|---|---|---|
| Ø32 | Ø12 | 48 | 41 |
| Ø40 ◄ | Ø16 | 75 | 63 |
| Ø50 | Ø20 | 118 | 99 |
Against Ø32, the Ø40 bore has 56 % more piston area and pushes 27 kg more at 6 bar; its pull-to-push ratio is 84 %.
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.
