About the Airtac MID Series Double Rod Mini Cylinder MID32X225S
Delivering 345.6 N of equal force in both directions at 0.5 MPa, this double-acting round-body mini cylinder uses a through-rod design where a piston rod exits both end covers. Because a rod occupies each side, the extend and retract areas are identical, completely eliminating the force differential found in single-rod units. The twin rod structure also resists rotation and side loads, providing steadier guiding for light jobs without needing an external guide.
Built with a stainless-steel barrel and rod, the riveted construction offers reliable mild corrosion and washdown resistance. It features a 1/4" port, a 12 mm piston rod, and operates at speeds between 30-800 mm/s. Equipped with a piston magnet (-S), it supports CMSG, DMSG, and EMSG switches for position sensing. For practical sizing, a safe working load is approximately 207 N (about 60% of the 0.5 MPa force), which translates to a vertical lift capacity of roughly 17.6 kg with a 2:1 safety margin.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G. Note: the Ø32 bore is a larger, non-ISO-6432 size.
Theoretical Output Force (Ø32mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 346 N |
| 0.7 MPa | 484 N |
| Max (@1.0 MPa) | 70 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

Where the Airtac MID Series Double Rod Mini Cylinder MID32X225S Is Used
Symmetric Shuttle Diverting
Ideal for pushing packages on a conveyor using its 345.6 N equal force, with the extended back rod available to trip a return switch.
Guided Stamping Press
The twin 12 mm rod resists rotation during 225 mm stamping or pressing tasks, ensuring the tool face stays perfectly aligned.
Dual-End Stopper Gate
Use both rod ends to actuate a physical stop barrier and a position flag simultaneously in washdown-resistant stainless assemblies.
Is the Airtac MID Series Double Rod Mini Cylinder MID32X225S the Right Cylinder?
When sizing this 32 mm bore, consider that the smaller MID25 provides 206.1 N at 0.5 MPa, while the larger MID40 delivers 527.8 N at 0.5 MPa. This model fits applications needing around 345.6 N of equal bidirectional force. The through-rod design is specifically beneficial when you need anti-rotation stability, a back-rod end to trip a switch or carry a stop, or to drive a second load simultaneously.
For mounting, you can utilize LB foot, FA flange, or TC trunnion options, as well as CA, U, R, or CM back covers, but note the SDB pivot-block is not available on this double-rod variant. Remember that the fixed TPU bumper pads only soften the stroke end; they do not lock the piston. If air pressure is lost, the cylinder will drift, so use an external rod lock or pilot check valve for load holding.
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 MID32X225S FAQ
Because it is a double-rod cylinder, the force is equal both ways: 345.6 N at 0.5 MPa, 483.8 N at 0.7 MPa, and a maximum theoretical force of 70.5 kgf at 1.0 MPa. It uses a 1/4" port.
No, the piston will drift on air loss. The fixed TPU bumpers only decelerate the stroke end and do not act as a brake. For holding a vertical load, you must use an external rod lock or pilot check valve. The -S magnet enables CMSG/DMSG/EMSG sensors.
