Airtac MI8~12 Stainless Steel Mini Cylinder MI12X5SCA
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI12X5SCA is a genuine double acting round-body mini air cylinder with a Ø12mm bore and 5mm 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 MI12X5SCA
Generating 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles short 5 mm strokes with precision. The riveted round body and Ø6 mm piston rod shrug off mild corrosion, making it far superior to painted alternatives in damp washdown environments. Because the bore is Ø12, it shares standard ISO 6432 mounting dimensions, dropping seamlessly into existing mini-cylinder brackets.
Fitted with a CA pivot clevis, the unit accommodates angular rod movement. The integrated piston magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing, while fixed TPU bumper pads absorb end-of-stroke impact. For practical sizing, plan for roughly 34 N of usable work at 0.5 MPa, which translates to lifting about 2.9 kg vertically with a 2:1 safety margin.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X5SCA Is Used
Clamp Mechanisms
Delivers rapid 5 mm clamping action on small pneumatic fixtures, using its 56.5 N thrust to secure light components during machining.
Valve Actuation
Pivots small process valves via the CA clevis, offering precise 5 mm travel for flow control in compact packaging machinery.
Gate Diverters
Shifts lightweight sorting gates on conveyor lines, where the stainless build resists moisture and the short stroke snaps parts into position.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X5SCA the Right Cylinder?
When sizing this 5 mm stroke unit, the smaller Ø8 bore provides just 25.1 N of push at 0.5 MPa, whereas stepping up to the Ø16 bore yields 100.5 N. This model hits a compact sweet spot for tight pivoting mechanisms. Note that venting the air or centering the valve causes the piston to drift; the bumper pads only decelerate the stroke end and do not function as a brake. To suspend a load securely, install an external pilot check valve. The M5x0.8 port matches the bore size, and the CA rear cover supplies the pivot mount.
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 MI12X5SCA 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.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only decelerate the stroke end and act as a brake. For vertical load holding, use an external rod lock or pilot check valve.
