Airtac MID Series Double Rod Mini Cylinder MID25X25
The AirTAC Airtac MID Series Double Rod Mini Cylinder MID25X25 is a genuine double acting, double rod round-body mini air cylinder with a Ø25mm bore and 25mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MID Series Double Rod Mini Cylinder MID25X25
Delivering 206.1 N of thrust in both directions at 0.5 MPa, this AirTAC round-body mini cylinder uses a through-rod design to equalize extend and retract forces. Because a Ø10 mm piston rod exits both end covers, the twin-rod geometry naturally resists rotation and side-load twisting without needing an external guide. The stainless-steel barrel and rod supply mild washdown corrosion resistance, while the 1/8" port feeds the double-acting chambers. It conforms to the ISO 6432 mounting interface for easy bracket drops.
With a 25 mm stroke, it generates a safe working load of roughly 124 N (about 60% of the 0.5 MPa figure) and vertically lifts around 10.5 kg with a 2:1 safety margin. The fixed TPU bumper pads decelerate the stroke ends but do not lock the piston. Note this specific SKU lacks the -S magnet, so it cannot host CMSG, DMSG, or EMSG sensors.

Where the Airtac MID Series Double Rod Mini Cylinder MID25X25 Is Used
Symmetric Shuttle
Drives a 10 kg work carrier back and forth with identical 206.1 N force on both strokes, using the rear rod end to trip a mechanical flag.
Guided Push Station
Holds a steady, twist-free alignment when pressing light fittings, relying on the twin rod to resist side loads without an external guide.
Dual-End Diverter
Actuates a sorting flap while simultaneously moving a secondary linkage on the opposite side, capitalizing on the through-rod extension.
Is the Airtac MID Series Double Rod Mini Cylinder MID25X25 the Right Cylinder?
If you need less push, the MID20 bore drops the 0.5 MPa output to 131.9 N; stepping up to the MID32 raises it to 345.6 N. Choose this twin-rod format when you need anti-rotation stability, want to mount a stop or switch on the back rod end, or need to drive two synchronized loads. For position holding, know that air loss causes drift—install an external rod lock or pilot check valve. Mount via LB foot, FA flange, or TC trunnion (the SDB pivot block is unavailable here), and select an -S variant if you require sensing.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MID Series Double Rod Mini Cylinder MID25X25 FAQ
It provides equal force both ways: 206.1 N at 0.5 MPa, 288.5 N at 0.7 MPa, and a maximum theoretical 42.0 kgf at 1.0 MPa. The air port is 1/8".
No, this SKU lacks the internal magnet so it cannot take CMSG, DMSG, or EMSG switches. You must order the -S variant for magnetic sensing.
