About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X90SCA
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 Ø12 mm barrel and rod shrug off mild corrosion, making it a superior choice over painted alternatives in damp or washdown-prone environments. Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG, or EMSG position switches.
Its 90 mm stroke operates within the 250 mm standard limit, and the built-in fixed TPU bumper pads quietly absorb end-of-travel impacts without the tuning hassle of an adjustable cushion. For practical sizing, plan for a safe working load of about 34 N (roughly 60% of the 0.5 MPa rating), which translates to lifting a 2.9 kg part vertically with a 2:1 safety margin. The M5x0.8 air port and M6x1.0 male rod thread keep pneumatic and mechanical connections straightforward.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X90SCA Is Used
Package Diverter Gate
Pivots a lightweight routing flap on a packaging line using its CA clevis, easily handling the 34 N safe working load to redirect small cartons.
Lab Sample Ejector
Pushes tested vials out of a centrifuge carousel with a precise 90 mm stroke, relying on the stainless build to resist chemical humidity.
Small Part Sorter
Actuates a sorting arm in an electronics assembly machine, using the -S magnet and a DMSG sensor to confirm part ejection timing.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X90SCA the Right Cylinder?
When sizing this 12 mm bore, the smaller Ø8 generates just 25.1 N of push at 0.5 MPa, while the larger Ø16 offers 100.5 N, giving you clear boundaries for your force requirements. The CA rear pivot cover is ideal for clevis mounting, allowing the cylinder to articulate smoothly on moving machinery. Keep in mind that a plain double-acting cylinder drifts when air is removed or a valve is centered; the TPU bumpers only decelerate the stroke end and will not lock the load, so add an external rod lock or pilot check valve if you need strict position holding. For the 90 mm stroke, ensure your guiding structure prevents side-loading to avoid bending the Ø6 mm piston rod.
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 MI12X90SCA FAQ
At 0.5 MPa it provides 56.5 N push and 42.4 N pull. At 0.7 MPa it provides 79.1 N push and 59.4 N pull. The theoretical maximum force is 11.5 kgf at 1.0 MPa. This model uses an M5x0.8 pneumatic port.
Yes, the Ø12 mm bore uses the ISO 6432 mounting interface, so it drops directly into standard mini-cylinder brackets and clevises. Additionally, the -S suffix means it has an internal magnet ready for CMSG, DMSG, or EMSG reed and electronic switches.
