250 mm Pneumatic Cylinder: Force Chart and Air Consumption
A 250 mm bore pneumatic cylinder (≈ 9.84 in) has a Ø50 mm rod and, per the Fenitsa catalogue, pushes 2,944 kg and pulls 2,827 kg at 6 bar (87 psi). Its piston area is 490.9 cm².
Typical uses: heavy loads where oil is not wanted, large dampers and flaps, heavy pressing. Standard strokes 50–500 mm; any stroke on request up to 2,800 mm for Ø250.

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) | 19,635 | 2,002 | 4,414 | 1,922 |
| 6 bar (87 psi) | 29,452 | 3,003 | 6,621 | 2,883 |
| 8 bar (116 psi) | 39,270 | 4,004 | 8,828 | 3,844 |
| 10 bar (145 psi) | 49,087 | 5,006 | 11,035 | 4,805 |
Catalogue at 6 bar: push 2,944 kg, pull 2,827 kg.
Air Consumption (6 bar, double stroke)
Free air in litres.
| Stroke (mm) | Air (L) |
|---|---|
| 50 | 33.3 |
| 100 | 66.6 |
| 200 | 133.2 |
| 300 | 199.8 |
| 500 | 333.0 |
Series and Mountings in This Bore
FMY (ISO 15552, magnetic piston, adjustable cushioning), PNS-PNSY (CETOP RP 53P) and PMB; 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 1,250 kg load at a 50 % load ratio (usual for moving loads), a Ø250 cylinder needs about 5.0 bar (72 psi).
Compared with Neighbouring Bores
| Bore | Rod | Push 6 bar (kg) | Pull 6 bar (kg) |
|---|---|---|---|
| Ø200 | Ø40 | 1,884 | 1,789 |
| Ø250 ◄ | Ø50 | 2,944 | 2,827 |
| Ø320 | Ø63 | 4,823 | 4,638 |
Against Ø200, the Ø250 bore has 56 % more piston area and pushes 1,060 kg more at 6 bar; its pull-to-push ratio is 96 %.
Frequently Asked Questions
How much force does a 250 mm pneumatic cylinder produce?
Per the catalogue, 2,944 kg push and 2,827 kg pull at 6 bar; at 10 bar the theoretical push is 5,006 kgf (11,035 lbf).
What rod size does a 250 mm cylinder have?
Ø50 mm (1.97 in).
How much air does a 250 mm cylinder use?
About 66.6 litres of free air per double stroke for a 100 mm stroke at 6 bar.
What load can a Ø250 cylinder move at 6 bar?
About 1,500 kg as a moving load at a 50 % load ratio; for static clamping up to the catalogue 2,944 kg.
