Airtac MI8~12 Stainless Steel Mini Cylinder MI12X90SU
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI12X90SU is a genuine double acting round-body mini air cylinder with a Ø12mm bore and 90mm 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 MI12X90SU
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation tasks with ease. The riveted barrel and Ø6 mm piston rod shrug off mild corrosion, making it a hardier choice than painted alternatives in damp work areas. Because the bore is Ø12, it carries the ISO 6432 mounting interface, dropping smoothly into standard mini-cylinder brackets and clevises.
The integrated piston magnet (-S) supports CMSG, DMSG, and EMSG switches for position sensing, while the U-style 90-degree rear cover simplifies side-mounting. Plan for roughly 34 N of actual work at 0.5 MPa, which translates to lifting about 2.9 kg vertically with a 2:1 safety margin. Fixed TPU bumper pads absorb stroke-end impacts across the 90 mm travel.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X90SU Is Used
PCB Depaneling Gate
Cycles a lightweight routing blade across 90 mm to singulate printed circuit boards, utilising the 56.5 N push force to maintain steady cutting pressure.
Blister Pack Flap Closer
Swings a hinged tucker plate via the 90-degree U rear cover to seal pharmaceutical blister packs, where the stainless body resists humid cleanroom air.
Lab Tube Ejector
Pushes centrifuge tubes out of a heated carousel block, lifting roughly 2.9 kg of carrier mass safely at 0.5 MPa with position feedback from a DMSG sensor.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X90SU the Right Cylinder?
If 56.5 N at 0.5 MPa feels excessive for your fixture, step down to the Ø10 bore (39.3 N push); if you need more authority, the Ø16 bore provides 100.5 N. The 90 mm stroke sits well within the 250 mm maximum for this bore, keeping rod bending stress low. This SKU includes the -S magnet for sensors and a U back cover for 90-degree mounting. Remember that venting the air causes the piston to drift; fit an external pilot check valve if the mechanism must hold a load vertically.
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 MI12X90SU FAQ
It generates 56.5 N push and 42.4 N pull at 0.5 MPa, or 79.1 N push and 59.4 N pull at 0.7 MPa, with a theoretical max of 11.5 kgf at 1.0 MPa. The air port is M5x0.8 and the male rod thread is M6x1.0.
No, the piston will drift if air pressure is lost or the valve is centred; the fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. Use an external rod lock or pilot check valve for load holding, and rely on the -S magnet with CMSG/DMSG/EMSG switches for end-of-stroke detection.
