Airtac MID Series Double Rod Mini Cylinder MID12X70
The AirTAC Airtac MID Series Double Rod Mini Cylinder MID12X70 is a genuine double acting, double rod round-body mini air cylinder with a Ø12mm bore and 70mm 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 MID12X70
Delivering 42.4 N of thrust at 0.5 MPa in both directions, this AirTAC MID12X70 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, guaranteeing equal force while resisting rotation and side loads without needing an external guide.
The stainless-steel round barrel and dual rods offer mild corrosion resistance for washdown environments. It uses the ISO 6432 mini-cylinder mounting interface for easy bracket integration. With an M5x0.8 air port and a 70 mm stroke, it provides a safe working load of roughly 25 N, or about 2.2 kg of vertical lift with a 2:1 margin. Note this SKU lacks a magnet and cannot host sensors.

Where the Airtac MID Series Double Rod Mini Cylinder MID12X70 Is Used
Symmetric Shuttle Transfer
Drives a lightweight parts shuttle back and forth with 42.4 N of equal force, using the twin rod to keep the carriage steady without external guides.
Back-Rod Switch Tripping
Uses the exposed rear rod end to physically trigger an external limit switch, ideal for tight spaces where mounting a magnetic sensor on the body is not possible.
Lab Dispense Head
Pushes a small fluid dispense head down with a consistent 25 N safe working load, relying on the stainless build for mild chemical splash resistance.
Is the Airtac MID Series Double Rod Mini Cylinder MID12X70 the Right Cylinder?
If your application requires less force, the MID10X70 provides 33.0 N at 0.5 MPa; stepping up to the MID16X70 yields 86.4 N. The twin-rod design is ideal for steady guided pushes, tripping a switch via the back rod end, or driving a symmetric shuttle. Keep in mind the fixed TPU bumper pads only decelerate the stroke end—they do not lock the piston. If you need to hold a load during air loss, install an external rod lock or pilot check valve. Mounting options include LB foot, FA flange, and TC trunnion (the SDB pivot-block is not available on this double-rod variant). For position sensing, you must select the -S magnet version to use CMSG, DMSG, or EMSG switches.
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 MID12X70 FAQ
Yes, force is equal both ways because a rod occupies each side. It delivers 42.4 N at 0.5 MPa, 59.4 N at 0.7 MPa, and a maximum theoretical force of 8.6 kgf at 1.0 MPa.
No, this specific SKU does not have a magnet. You must order the -S variant to use CMSG, DMSG, or EMSG sensors. The stainless steel round-body construction resists mild corrosion.
