Airtac MID Series Double Rod Mini Cylinder MID20X80
The AirTAC Airtac MID Series Double Rod Mini Cylinder MID20X80 is a genuine double acting, double rod round-body mini air cylinder with a Ø20mm bore and 80mm stroke, 1/8" 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 MID20X80
Delivering 131.9 N of thrust at 0.5 MPa in both directions, this stainless steel round-body mini cylinder uses a through-rod design that extends from both end covers. Because a rod occupies each side, the extend and retract forces are perfectly equal, and the twin-rod construction naturally resists rotation and side loads for steadier guiding without an external guide. The Ø20 mm bore uses an M8x1.25 male rod thread and a 1/8" air port.
Built with a riveted stainless barrel and rod, it withstands mild corrosion and washdown environments. It conforms to the ISO 6432 mounting interface for standard mini brackets. Based on the 0.5 MPa rating, it offers a safe working load of roughly 79 N, meaning it can vertically lift about 6.7 kg with a 2:1 safety margin. Note this SKU lacks a magnet and cannot take sensors; the -S variant enables CMSG/DMSG/EMSG switches.

Where the Airtac MID Series Double Rod Mini Cylinder MID20X80 Is Used
Guided Push Station
With 131.9 N of equal force both ways, the twin rod resists rotation to deliver steady, aligned pushes for small part seating without an external guide.
Symmetric Shuttle
Driving a load from both rod ends simultaneously allows this cylinder to act as a compact, balanced transfer shuttle in light assembly lines.
Back-Rod Switch Trip
The exposed rear rod end is perfect for mechanically tripping a limit switch or carrying a physical stop flag, independent of the main work side.
Is the Airtac MID Series Double Rod Mini Cylinder MID20X80 the Right Cylinder?
If you need less force, the MID16 bore provides 86.4 N at 0.5 MPa, while stepping up to the MID25 yields 206.1 N. This Ø20 model is ideal when you need the back rod end to trip a switch, carry a stop, or drive a second load. For mounting, use LB foot, FA flange, or TC trunnion brackets (the SDB pivot-block is unavailable for double-rods). Keep in mind the fixed TPU bumpers only soften stroke ends; the piston will drift on air loss, so add an external rod lock or pilot check valve to hold a suspended load.
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 MID20X80 FAQ
It delivers equal force in both directions: 131.9 N at 0.5 MPa, 184.7 N at 0.7 MPa, and a maximum theoretical 26.9 kgf at 1.0 MPa. The air port is 1/8".
No, this specific SKU does not have a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You must order the -S variant to enable magnetic sensing.
