About the Airtac MID Series Double Rod Mini Cylinder MID12X25S
Delivering 42.4 N of thrust at 0.5 MPa in both directions, the AirTAC MID12X25S is a double-acting, through-rod mini cylinder. Because a Ø6 mm piston rod exits both end covers, the extend and retract areas are identical, ensuring perfectly balanced force while the twin rod naturally resists rotation and side loads without needing an external guide.
The stainless-steel round barrel and dual rods shrug off mild corrosion and washdown environments, conforming to the ISO 6432 mounting interface for easy bracket integration. This -S variant includes a piston magnet for position sensing. With a safe working load around 25 N, it can vertically lift about 2.2 kg each way with a 2:1 margin. Air connects via M5x0.8 ports, operating at 30-800 mm/s.

Where the Airtac MID Series Double Rod Mini Cylinder MID12X25S Is Used
Symmetric Shuttle Transfer
Drives a light parts shuttle back and forth with 42.4 N of equal force on both strokes, using the twin rod to keep the carrier steady and prevent rotation during transit.
Back-Rod Switch Trip
Uses the protruding rear rod end to physically trigger an external limit switch or flag, while the internal -S magnet simultaneously fires a CMSG sensor for dual confirmation.
Guided Pin Insertion
Pushes delicate pins or probes with 25 N of safe working load, relying on the anti-rotation properties of the through-rod to maintain alignment without a separate guide bushing.
Is the Airtac MID Series Double Rod Mini Cylinder MID12X25S the Right Cylinder?
When sizing this bore, stepping down to the MID10X25S halves the output to 33.0 N at 0.5 MPa, while stepping up to the MID16X25S raises it to 86.4 N. Choose this Ø12 mm model when you need symmetric push-pull action, a back-rod end to trip a switch or carry a stop, or steady guiding for light loads. It uses fixed TPU bumper pads to soften stroke ends, but note that a bumper is not a lock; the piston will drift on air loss, so fit an external rod lock or pilot check valve to hold a suspended load.
Mounting options include LB foot, FA flange, and TC trunnion brackets, but the SDB pivot block is not offered for this double-rod variant. Because this SKU has the -S magnet, you can directly mount CMSG, DMSG, or EMSG reed and electronic sensors to track position.
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 MID12X25S FAQ
It delivers equal force both ways because the double rod occupies each side: 42.4 N at 0.5 MPa, 59.4 N at 0.7 MPa, and a maximum theoretical output of 8.6 kgf at 1.0 MPa. It operates at speeds of 30-800 mm/s.
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 vertical loads, use an external rod lock or pilot check valve. The stainless build and -S magnet allow washdown use with CMSG sensors.
