Airtac MI8~12 Stainless Steel Mini Cylinder MI8X80U
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI8X80U is a genuine double acting 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 MI8~12 Stainless Steel Mini Cylinder MI8X80U
Delivering 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact 80 mm stroke tasks with a 90-degree U rear cover. The riveted round body and Ø4 mm rod shrug off mild corrosion, giving a real edge over painted alternatives in damp or washdown spots. It uses the ISO 6432 mounting interface, dropping directly into standard mini-cylinder brackets and clevises.
Fixed TPU bumper pads soften the impact at stroke end, though they only decelerate rather than cushion adjustably. Plan for roughly 15 N of actual work at 0.5 MPa, which translates to lifting about 1.3 kg vertically with a 2:1 safety margin. The M5x0.8 port feeds air to both extend and retract the rod, operating at 30-800 mm/s.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X80U Is Used
Micro-Clamp Actuation
Drives small pneumatic clamps in PCB routing stations, using its 25.1 N thrust to secure light fibreglass panels during milling.
Lab Dispenser Ejection
Pushes finished vials out of a filling carousel with an 80 mm travel, relying on the stainless body to endure daily alcohol wipe-downs.
Small Part Transfer
Indexes tiny plastic caps into a capping head, where the 90-degree U cover neatly tucks the M5x0.8 air line out of the moving path.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X80U the Right Cylinder?
When sizing this 8 mm bore, the next step up is the Ø12 class offering 56.5 N push at 0.5 MPa, while there is no smaller standard MI bore below this. Because this SKU lacks the -S suffix, it cannot accept CMSG, DMSG or EMSG magnetic switches; you would need the magnet-equipped variant for position sensing. The U-style back cover provides a 90-degree port and mounting orientation for tight spaces.
An 80 mm stroke on a slender Ø4 mm rod demands careful alignment to prevent side-loading and rod bending. Furthermore, the plain piston drifts if air is lost or the valve is centred—the bumper pads only soften the end of travel and act purely as a decelerator, never as a lock or brake. To suspend a load safely mid-stroke, fit an external rod lock or a pilot-operated check valve.
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 MI8~12 Stainless Steel Mini Cylinder MI8X80U FAQ
At 0.5 MPa it pushes 25.1 N and pulls 18.8 N; at 0.7 MPa it pushes 35.2 N and pulls 26.4 N. The theoretical maximum force is 5.1 kgf at 1.0 MPa. It features an M5x0.8 air port and a maximum standard stroke of 150 mm.
No, this specific SKU lacks a magnet and cannot accept CMSG, DMSG or EMSG switches. You must specify the -S variant for position sensing. The cylinder uses fixed TPU bumper pads for end-of-stroke deceleration and conforms to ISO 6432 mounting dimensions.
