About the Airtac MID Series Double Rod Mini Cylinder MID32X125S
Delivering 345.6 N of thrust at 0.5 MPa in both directions, this AirTAC double-acting mini cylinder uses a through-rod design where a piston rod exits both end covers. Because both faces use the identical rod-side area, extend and retract forces are perfectly equal. The twin-rod construction inherently resists rotation and side loads, providing steady guided motion for light jobs without needing an external guide.
Built as a round-body, riveted stainless-steel unit, the barrel and rod shrug off mild corrosion and washdown environments. This bore size is a non-ISO-6432 round-body mini cylinder, operating at 30-800 mm/s with a 1/4" port. Equipped with a built-in magnet (-S), it supports CMSG, DMSG, and EMSG switches. For a practical buyer insight, the safe working load is roughly 207 N, meaning it can vertically lift about 17.6 kg each way 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 MID32X125S Is Used
Symmetric Shuttle Transfer
Drives a 17.6 kg payload back and forth with 345.6 N of equal force, using the twin rod to keep the shuttle steady without twisting.
Dual-End Switch Trip
Uses the protruding back rod end to physically trigger a limit flag or secondary switch while the front rod executes the main 125 mm work stroke.
Guided Push Operation
Pushes a component with 483.8 N at 0.7 MPa, relying on the double-rod geometry to resist side-load binding during the extension.
Is the Airtac MID Series Double Rod Mini Cylinder MID32X125S the Right Cylinder?
When sizing this 32 mm bore, step down to a MID25 (206.1 N at 0.5 MPa) for lighter duties, or step up to a MID40 (527.8 N at 0.5 MPa) if you need more muscle. The through-rod shines in applications needing anti-rotation stability, a back-rod switch trip, or a twin-load drive. For mounting, utilize LB foot, FA flange, or TC trunnion brackets, plus CA, U, R, or CM back covers. Note that the SDB pivot-block is not available on this double-rod variant.
The -S magnet enables position sensing with CMSG, DMSG, or EMSG switches. 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 install an external rod lock or pilot check valve to hold a suspended load safely.
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 MID32X125S FAQ
Because it is a double-rod cylinder, the force is equal both ways. It delivers 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.
Yes, the -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG switches. However, it does not hold position on air loss; the piston drifts, so use an external rod lock for suspended loads.
