Airtac MID Series Double Rod Mini Cylinder MID12X80S
The AirTAC Airtac MID Series Double Rod Mini Cylinder MID12X80S is a genuine double acting, double rod round-body mini air cylinder with a Ø12mm bore and 80mm 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 MID12X80S
Delivering 42.4 N of thrust at 0.5 MPa in both directions, this stainless steel round-body mini cylinder uses a through-rod design to ensure extend and retract forces remain identical. Because a Ø6 mm rod exits both end covers, the twin-rod structure inherently resists rotation and side loads, providing steadier guiding for light tasks without needing an external guide. The back rod end is also free to trip a switch or carry a stop. With an 80 mm stroke and M5x0.8 port, it yields a safe working load of about 25 N, or roughly 2.2 kg of vertical lift with a 2:1 margin.
Built with a mildly corrosion-resistant stainless barrel and rod, it handles washdown environments and conforms to the ISO 6432 mounting interface for standard mini brackets. The -S suffix indicates a built-in piston magnet, enabling position sensing with CMSG, DMSG, or EMSG switches. Fixed TPU bumper pads decelerate the stroke ends, operating reliably at speeds between 30 and 800 mm/s across a -20 to +70 C range.

Where the Airtac MID Series Double Rod Mini Cylinder MID12X80S Is Used
Symmetric Component Shuttle
With 42.4 N of equal force both ways, this cylinder smoothly pushes and pulls light parts between two stations without stroke imbalance.
Rear-Rod Switch Trip
The extending back rod trips an external limit switch or carries a physical flag, confirming position while the front rod handles the 25 N working load.
Guided Pick-and-Place
The twin-rod anti-rotation特性 keeps a small gripper steady during vertical lifts up to 2.2 kg, preventing torsional twist without external guides.
Is the Airtac MID Series Double Rod Mini Cylinder MID12X80S the Right Cylinder?
When sizing this bore, stepping down to the MID10X80S reduces the equal-both-ways force to 33.0 N at 0.5 MPa, while stepping up to the MID16X80S raises it to 86.4 N. The double-rod layout is specifically chosen when anti-rotation stability is required, when the rear rod must drive a second load, or when a back-rod stop is needed. Note that the fixed bumpers only soften the end of stroke; they do not hold position. If air pressure drops, the piston will drift, so add an external rod lock or pilot check valve for suspended loads.
Mounting options include LB foot, FA flange, and TC trunnion styles, but the SDB pivot block is not available on this double-rod variant. Because this is the -S magnet version, it is fully ready for CMSG, DMSG, or EMSG sensor integration.
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 MID12X80S FAQ
It delivers equal force in both directions because the double-rod design uses the rod-side area on each face. It provides 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. The air port is M5x0.8.
No, the piston will drift on air loss. The fixed TPU bumpers only decelerate the stroke end and do not act as a lock. For holding suspended loads, use an external rod lock or pilot check valve. The -S magnet enables CMSG/DMSG/EMSG sensors for position confirmation.
