63 mm Pneumatic Cylinder: Force Chart and Air Consumption
A 63 mm bore pneumatic cylinder (≈ 2.48 in) has a Ø20 mm rod and, per the Fenitsa catalogue, pushes 187 kg and pulls 168 kg at 6 bar (87 psi). Its piston area is 31.2 cm².
Typical uses: general automation — the most used bore, pushing boxes and cartons, lifting light loads. Standard strokes 50–500 mm; any stroke on request up to 3,000 mm for Ø63.

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) | 1,247 | 127 | 280 | 114 |
| 6 bar (87 psi) | 1,870 | 191 | 420 | 172 |
| 8 bar (116 psi) | 2,494 | 254 | 561 | 229 |
| 10 bar (145 psi) | 3,117 | 318 | 701 | 286 |
Catalogue at 6 bar: push 187 kg, pull 168 kg.
Air Consumption (6 bar, double stroke)
Free air in litres.
| Stroke (mm) | Air (L) |
|---|---|
| 50 | 2.0 |
| 100 | 4.1 |
| 200 | 8.2 |
| 300 | 12.3 |
| 500 | 20.5 |
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 80 kg load at a 50 % load ratio (usual for moving loads), a Ø63 cylinder needs about 5.0 bar (73 psi).
Compared with Neighbouring Bores
| Bore | Rod | Push 6 bar (kg) | Pull 6 bar (kg) |
|---|---|---|---|
| Ø50 | Ø20 | 118 | 99 |
| Ø63 ◄ | Ø20 | 187 | 168 |
| Ø80 | Ø25 | 301 | 272 |
Against Ø50, the Ø63 bore has 59 % more piston area and pushes 69 kg more at 6 bar; its pull-to-push ratio is 90 %.
Frequently Asked Questions
How much force does a 63 mm pneumatic cylinder produce?
Per the catalogue, 187 kg push and 168 kg pull at 6 bar; at 10 bar the theoretical push is 318 kgf (701 lbf).
What rod size does a 63 mm cylinder have?
Ø20 mm (0.79 in).
How much air does a 63 mm cylinder use?
About 4.1 litres of free air per double stroke for a 100 mm stroke at 6 bar.
What load can a Ø63 cylinder move at 6 bar?
About 95 kg as a moving load at a 50 % load ratio; for static clamping up to the catalogue 187 kg.
