Airtac MI8~12 Stainless Steel Mini Cylinder MI12X75U
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI12X75U is a genuine double acting round-body mini air cylinder with a Ø12mm bore and 75mm 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 MI12X75U
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 75 mm stroke with a 12 mm bore. The riveted barrel and rod shrug off mild corrosion, outperforming painted alternatives in damp or washdown settings. Its M5x0.8 port and M6x1.0 male rod thread keep pneumatic and mechanical hookups compact.
Because it follows ISO 6432 mounting dimensions, the body drops directly into standard mini-cylinder brackets and clevises, easing design and spares. Plan for roughly 34 N of actual work at 0.5 MPa, which translates to lifting about 2.9 kg vertically with a safe 2:1 margin. Fixed TPU bumper pads absorb end-of-stroke impact, and the U back cover provides a 90-degree port orientation for tight routing.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X75U Is Used
Small Parts Ejection
Pushes lightweight plastic or stamped metal parts out of a die with 56.5 N of force, relying on the 75 mm stroke to clear the mold bed entirely.
Package Diverting
Actuates a 90-degree routing gate on a packaging line, where the stainless body resists washdown and the U cover keeps air lines tidy.
PCB Clamp Jigs
Secures delicate circuit boards during ultrasonic welding, applying a safe 34 N working load to prevent board flexing without crushing components.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X75U the Right Cylinder?
When sizing this 12 mm bore, the smaller 8 mm option yields 25.1 N of push, while stepping up to the 16 mm bore provides 100.5 N at 0.5 MPa. This makes the 12 mm unit the sweet spot for medium-duty clamping or lifting around 2.9 kg. For the 75 mm stroke, ensure your guiding is square to prevent rod side-loading and premature seal wear.
This specific SKU lacks the -S magnet, so it cannot host CMSG, DMSG, or EMSG position switches; choose an -S variant if you need electronic end-of-stroke confirmation. Remember that venting the air causes the piston to drift, as the TPU bumpers only decelerate the stroke end rather than locking the load. Use an external pilot check valve to hold a suspended weight.
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 MI12X75U FAQ
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N. At 0.7 MPa it pushes 79.1 N and pulls 59.4 N. The theoretical maximum force is 11.5 kgf at 1.0 MPa. The air port is M5x0.8 and the male rod thread is M6x1.0.
No, this SKU does not include the -S magnet, so CMSG, DMSG, or EMSG switches cannot be fitted. You would need the MI12X75SU variant for position sensing. It uses fixed TPU bumper pads and follows ISO 6432 mounting dimensions.
