Airtac MID Series Double Rod Mini Cylinder MID8X80
The AirTAC Airtac MID Series Double Rod Mini Cylinder MID8X80 is a genuine double acting, double rod round-body mini air cylinder with a Ø8mm 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 MID8X80
Delivering 18.8 N of thrust at 0.5 MPa in both directions, the AirTAC MID8X80 is a compact double-acting round-body mini cylinder. Because a Ø4 mm piston rod exits both end covers, the extend and retract areas are identical, ensuring equal force while the twin-rod geometry naturally resists rotation and side loads without needing an external guide.
Built with a stainless-steel barrel and rod for mild corrosion and washdown resistance, this 8 mm bore unit conforms to the ISO 6432 mounting interface for easy bracket integration. It travels an 80 mm stroke at speeds from 30 to 800 mm/s. The fixed TPU bumper pads decelerate the piston near stroke ends. Note that this specific SKU lacks a magnet, so it cannot host CMSG, DMSG, or EMSG sensors; the -S variant is required for position detection. Ports are M5x0.8.

Where the Airtac MID Series Double Rod Mini Cylinder MID8X80 Is Used
Micro-Part Ejection
With a safe working load around 11 N (roughly 60% of its 0.5 MPa force), this cylinder reliably pushes small plastic or electronic components out of a machining fixture without rotating the part.
Symmetric Shuttle Transfer
The equal force both ways and twin-rod stability make it ideal for shuttling lightweight trays between two stations, ensuring the payload stays level during rapid 80 mm transfers.
Cam Switch Tripping
The exposed rear rod end can be fitted with a custom flag or cam to mechanically trip a limit switch at the end of the retract stroke, useful since this non-magnet SKU cannot carry a hall-effect sensor.
Is the Airtac MID Series Double Rod Mini Cylinder MID8X80 the Right Cylinder?
When sizing this 8 mm bore, consider stepping up to the MID10X80 if your application requires more push, as the 10 mm bore provides 33.0 N at 0.5 MPa compared to this model's 18.8 N. There is no smaller MID bore available, making this the baseline for ultra-light tasks. The double-rod design is highly beneficial when you need a back-rod extension to trip a switch or carry a secondary stop. For load holding, remember that the bumper pads only soften the end of stroke and the piston will drift on air loss; use an external rod lock or pilot check valve to hold a load. Mounting options include LB, FA, and TC styles, but the SDB pivot block is not available for this double-rod variant.
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 MID8X80 FAQ
The MID8X80 provides equal force in both directions because it is a double-rod cylinder. It outputs 18.8 N at 0.5 MPa, 26.4 N at 0.7 MPa, and a maximum theoretical 3.8 kgf at 1.0 MPa. The operating pressure range is 0.15 to 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot be used with CMSG, DMSG, or EMSG sensors. You would need the MID8X80-S variant for position sensing. The stainless-steel build and fixed TPU bumpers still provide excellent mild corrosion resistance and stroke deceleration.
