Airtac MID Series Double Rod Mini Cylinder MID12X20
The AirTAC Airtac MID Series Double Rod Mini Cylinder MID12X20 is a genuine double acting, double rod round-body mini air cylinder with a Ø12mm bore and 20mm 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 MID12X20
Delivering 42.4 N of thrust at 0.5 MPa in both directions, this stainless-steel round-body mini cylinder uses a double-rod design to ensure equal extend and retract forces. The twin 6 mm rods exit both end covers, actively resisting rotation and side load to keep guiding steady for light jobs without needing an external guide. With an M5x0.8 port and a 20 mm stroke, it provides a safe working load of about 25 N, meaning it can vertically lift roughly 2.2 kg with a 2:1 safety margin.
Built to the ISO 6432 mounting interface, it drops directly into standard mini brackets and clevises. The stainless barrel and rods offer reliable mild corrosion and washdown resistance. This specific SKU lacks a magnet and cannot take a sensor; adding the -S option enables CMSG, DMSG or EMSG switches. Fixed TPU bumper pads decelerate the stroke ends, though they are not a lock.

Theoretical Output Force (Ø12mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 42 N |

Where the Airtac MID Series Double Rod Mini Cylinder MID12X20 Is Used
Symmetric Parts Shuttle
Drives a light 2 kg jig back and forth on a linear rail, using the equal both-ways force to push and pull components without speed variation.
Back-Rod Switch Trip
Uses the extended rear rod end to mechanically strike an external limit switch at 20 mm stroke, ideal when a magnet-free setup is preferred.
Guided Label Applicator
The twin 6 mm rods resist torsional side load during rapid 30-800 mm/s pressing, keeping a 25 N stamping head perfectly aligned.
Is the Airtac MID Series Double Rod Mini Cylinder MID12X20 the Right Cylinder?
When sizing this 12 mm bore, step down to the MID10X20 for 33.0 N at 0.5 MPa if your load is very light, or step up to the MID16X20 for 86.4 N if you need more force. The through-rod architecture is ideal when you need anti-rotation stability, want to trip a switch from the back rod end, or drive a symmetric shuttle. Choose LB foot, FA flange or TC trunnion mounts, as the SDB pivot-block is not available on this double-rod variant.
Because a plain cylinder drifts on air loss, do not rely on the TPU bumpers to hold a load. For vertical or suspended loads that must stay in place during a pressure drop, install an external rod lock or a pilot-operated check valve. If position sensing is required, select the -S magnet version to support CMSG, DMSG and 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 MID12X20 FAQ
Because a rod exits both ends, the force is equal both ways. It provides 42.4 N at 0.5 MPa, 59.4 N at 0.7 MPa, and a maximum of 8.6 kgf at 1.0 MPa. It uses an M5x0.8 port.
No, this specific SKU does not have a magnet and cannot take a sensor. You must choose the -S variant to use CMSG, DMSG or EMSG switches. The stainless steel build also provides mild washdown resistance.
