Airtac MI8~12 Stainless Steel Mini Cylinder MI12X175U
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI12X175U is a genuine double acting round-body mini air cylinder with a Ø12mm bore and 175mm 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 MI12X175U
Delivering 56.5 N of push force at 0.5 MPa, this 12 mm bore, 175 mm stroke actuator is built as a double-acting round-body stainless-steel mini cylinder. The riveted stainless barrel and Ø6 mm rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown-prone environments. Because it adheres to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises without custom hardware. At 0.5 MPa you can plan for roughly 34 N of actual work, which translates to lifting about 2.9 kg vertically with a 2:1 safety margin.
This specific SKU features a U-type back cover that orients the rear port 90 degrees to the body, simplifying hose routing in cramped spaces. It relies on fixed TPU bumper pads to decelerate the piston at stroke end rather than an adjustable air cushion. Note that this variant lacks the -S magnet, so it cannot host CMSG, DMSG or EMSG reed switches; order the -S version if you require position sensing. The air port is M5x0.8 and the male rod thread is M6x1.0.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X175U Is Used
Package Diverter Gate
Pivots a lightweight routing flap on a packaging conveyor to sort small cartons, utilizing the 90-degree U cover to keep the air line flush against the machine frame.
Lab Sample Ejector
Pushes tested specimen trays out of a damp analytical instrument station, where the stainless construction prevents mild corrosion from repeated chemical exposure.
Small Part Ejector
Kicks machined plastic components out of a molding fixture using the 56.5 N push force, safely moving parts weighing under 2.9 kg at a 0.5 MPa working pressure.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X175U the Right Cylinder?
When sizing this 12 mm bore, compare its 56.5 N push force at 0.5 MPa against the adjacent options: step down to the Ø10 for 39.3 N, or move up to the Ø16 for 100.5 N if your payload exceeds the safe 34 N working load. The 175 mm stroke is well within the 250 mm maximum standard stroke for this bore, but at that length you must carefully manage side loading to prevent rod bending and premature seal wear. You can mount it via LB foot, FA flange, SDB pivot or TC trunnion hardware.
Remember that a plain double-acting cylinder will drift if air pressure drops or the directional valve is centred; the TPU bumpers only soften the end-of-stroke impact and act as neither a brake nor a position lock. If your application demands the load stays put during an air loss event, install an external rod lock or a pilot-operated check valve in the line.
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 MI12X175U FAQ
The 12 mm bore generates a push force of 56.5 N and a pull force of 42.4 N at 0.5 MPa. At 0.7 MPa, push is 79.1 N and pull is 59.4 N. The theoretical maximum force is 11.5 kgf at 1.0 MPa. The air port size is M5x0.8.
No. This specific SKU lacks the internal magnet, so it cannot accept CMSG, DMSG or EMSG switches; you would need the -S variant for sensing. It uses fixed TPU bumper pads to decelerate the stroke end, not an adjustable air cushion. It does feature a 90-degree U back cover and standard ISO 6432 mounting dimensions.
