300 mm Stroke Pneumatic Cylinder
A 300 mm stroke (30 cm, 11.81 in) is a standard catalogue stroke and is available in every Fenitsa bore from Ø32 to Ø320. The stroke sets how far the rod travels and how much air each cycle uses; the bore sets the force.
Typical 300 mm stroke jobs: long transfers and pushers, sliding gates, tilting and positioning.

Force, Air and Buckling by Bore
Free air per double stroke at 6 and 8 bar; buckling limit with the cylinder pivoted at both ends (Lk ≈ 600 mm, safety factor 3.5).
| Bore / rod | Air 6 bar (L) | Air 8 bar (L) | Buckling limit (kg) |
|---|---|---|---|
| Ø32 / Ø12 | 3.11 | 3.99 | 171 |
| Ø40 / Ø16 | 4.80 | 6.17 | 540 |
| Ø50 / Ø20 | 7.50 | 9.64 | 1,317 |
| Ø63 / Ø20 | 12.30 | 15.80 | 1,317 |
| Ø80 / Ø25 | 19.86 | 25.52 | 3,216 |
| Ø100 / Ø25 | 31.60 | 40.62 | 3,216 |
| Ø125 / Ø32 | 49.30 | 63.37 | 8,634 |
| Ø160 / Ø40 | 80.91 | 103.98 | 21,078 |
| Ø200 / Ø40 | 127.89 | 164.36 | 21,078 |
At 300 mm every bore's rod carries more than its 6 bar push force, so buckling does not limit a pivoted cylinder.
Compressor Demand
Free air at 6 bar for 10 double strokes per minute.
| Bore | Air (L/min) |
|---|---|
| Ø40 | 48.0 |
| Ø63 | 123.0 |
| Ø100 | 316.0 |
| Ø160 | 809.1 |
Example: a Ø125 cylinder with a 300 mm stroke pushes 735 kg at 6 bar; at 10 cycles per minute it needs about 493.0 L/min of free air, or 29.58 m³/h.
Frequently Asked Questions
Is 300 mm a standard stroke?
Yes. Standard strokes are 50, 100, 125, 160, 200, 250, 300, 350, 400, 450 and 500 mm.
How much air does a Ø63 cylinder with 300 mm stroke use?
About 12.30 litres of free air per double stroke at 6 bar.
