Airtac MID Series Double Rod Mini Cylinder MID25X20
The AirTAC Airtac MID Series Double Rod Mini Cylinder MID25X20 is a genuine double acting, double rod round-body mini air cylinder with a Ø25mm bore and 20mm 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 MID25X20
Delivering 206.1 N of equal thrust in both directions at 0.5 MPa, this stainless-steel round-body mini cylinder uses a through-rod design to balance extend and retract forces. The twin rod exits both end covers, resisting rotation and side load for steadier guiding without an external guide. Because a rod occupies each side, both faces use the rod-side area, meaning you get 288.5 N at 0.7 MPa each way. The 1/8" port and M10x1.25 male rod thread equip this Ø25 bore for robust light-industrial tasks.
Built to the ISO 6432 mounting interface, it drops directly into standard mini brackets and clevises. The stainless barrel and rod resist mild corrosion and washdown environments. For a practical buyer insight, the 0.5 MPa output yields a safe working load of roughly 124 N, or a vertical lift of about 10.5 kg with a 2:1 safety margin. Note this specific SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors without switching to an -S variant.

Where the Airtac MID Series Double Rod Mini Cylinder MID25X20 Is Used
Symmetric Shuttle Transfer
Pushing a 10 kg component left and right with 206.1 N of equal force, utilizing the twin rod to keep the carriage steady without twisting.
Back-Rod Switch Trip
Using the rear rod extension to physically strike an external mechanical limit switch, since this non-magnet model cannot carry internal sensors.
Guided Pin Insertion
Driving a 124 N insertion load with the double-rod resisting side load and rotation for precise, bind-free pin seating.
Is the Airtac MID Series Double Rod Mini Cylinder MID25X20 the Right Cylinder?
When sizing this 25 mm bore, stepping down to a MID20 moves you to 131.9 N at 0.5 MPa, while stepping up to a MID32 provides 345.6 N. This model fits jobs needing around 124 N of safe working load. The through-rod is ideal when you need to drive a second load, trip a switch, or mount a stop on the back rod end. It operates at 30-800 mm/s.
Remember that fixed TPU bumper pads only soften the stroke end; they do not lock the piston. If air pressure drops, the cylinder drifts, so use an external rod lock or pilot check valve for held loads. Mounting options include LB foot, FA flange, and TC trunnion, but the SDB pivot-block is unavailable on this double-rod variant. Since this is a non-magnet SKU, position sensing is not possible.
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 MID25X20 FAQ
Because it is a double-rod cylinder, force is equal 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. It uses a 1/8" port.
No, this specific SKU does not include a magnet, so CMSG, DMSG, or EMSG sensors will not work. You must select the -S variant to enable sensing. The stainless build resists mild corrosion.
