Airtac MID Series Double Rod Mini Cylinder MID12X50
The AirTAC Airtac MID Series Double Rod Mini Cylinder MID12X50 is a genuine double acting, double rod round-body mini air cylinder with a Ø12mm bore and 50mm stroke, M5×0.8 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 MID12X50
Delivering 42.4 N of thrust at 0.5 MPa in both directions, the AirTAC MID12X50 is a stainless-steel round-body mini cylinder built for double-acting operation. Because a Ø6 mm piston rod exits both end covers, the extend and retract forces are perfectly equal, and the twin-rod geometry inherently resists rotation and side loads for steadier guiding without an external guide. The stainless barrel and rod withstand mild corrosion and washdown environments, and the unit conforms to the ISO 6432 mounting interface for standard mini brackets.
At 0.5 MPa, this bore yields a safe working load of roughly 25 N, capable of vertically lifting about 2.2 kg with a 2:1 safety margin. It operates at speeds from 30-800 mm/s, utilizing M5x0.8 air ports. The fixed TPU bumper pads decelerate the piston near stroke ends, though they do not lock the load. Note that this specific SKU lacks a magnet, so it cannot host CMSG, DMSG, or EMSG sensors without upgrading to the -S variant.

Where the Airtac MID Series Double Rod Mini Cylinder MID12X50 Is Used
Symmetric Shuttle
Drives a light shuttle carrier back and forth with 42.4 N of equal force, using the twin rod to prevent carriage twist during transfer.
Cam Switch Trip
Uses the extended back rod end to physically trigger an external mechanical limit switch, since this non-magnet SKU cannot carry reed sensors.
Guided Pin Insertion
Presses small pins or rivets with a steady 2.2 kg vertical load, relying on the through-rod to resist side-load binding without extra guides.
Is the Airtac MID Series Double Rod Mini Cylinder MID12X50 the Right Cylinder?
When sizing this 12 mm bore, consider the application force: if 42.4 N at 0.5 MPa is insufficient, step up to the MID16, which provides 86.4 N; conversely, lighter duties can use the MID10 at 33.0 N. The double-rod design is specifically advantageous when you need anti-rotation stability, want to trip a switch via the back rod end, or need to drive a symmetric load from both sides. Keep in mind the piston will drift on air loss, as the TPU bumpers only soften the stroke end rather than locking the position—use an external rod lock or pilot check valve for holding. Mounting options include LB foot, FA flange, and TC trunnion (the SDB pivot block is unavailable for double-rods), and you must select the -S magnet option if position sensing is required.
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 MID12X50 FAQ
The MID12X50 delivers an equal force both ways due to the double-rod design: 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 uses M5x0.8 ports.
No, this specific SKU does not include a magnet, so CMSG, DMSG, or EMSG sensors cannot be used. You must order the -S variant to enable magnetic position sensing.
