Airtac MI8~12 Stainless Steel Mini Cylinder MI12X70SCA
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI12X70SCA is a genuine double acting round-body mini air cylinder with a Ø12mm bore and 70mm 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 MI12X70SCA
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact linear actuation with a 70 mm stroke. The Ø12 mm bore uses an M5x0.8 air port and a Ø6 mm piston rod with an M6x1.0 male thread. Its riveted stainless barrel and rod shrug off mild corrosion, outlasting painted alternatives in damp environments. Because the -S suffix includes a piston magnet, you can mount CMSG, DMSG or EMSG reed switches for position sensing.
Built to ISO 6432 mounting dimensions, the body drops directly into standard mini-cylinder brackets and clevises. Fixed TPU bumper pads absorb stroke-end impact without the tuning an adjustable cushion demands. For real-world sizing, plan for roughly 34 N of usable work at 0.5 MPa; vertically, it lifts about 2.9 kg safely with a 2:1 margin.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X70SCA Is Used
Pick-and-Place Pivot
Uses the CA rear clevis to swing small electronic components during board transfer, relying on the 56.5 N thrust to push a lightweight gripper.
Film Clamp Assembly
Secures packaging film webs on vertical form-fill machines, where the stainless body resists washdown and the 70 mm stroke clears the film path.
Small Part Ejection
Pushes misaligned plastic caps off a conveyor at 30-800 mm/s, using the integrated magnet to trigger a DMSG sensor for the eject confirmation.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X70SCA the Right Cylinder?
This Ø12 mm bore sits between the lighter Ø10 mm (39.3 N push @0.5 MPa) and the stronger Ø16 mm (100.5 N push @0.5 MPa), giving you a clear upgrade path if your payload shifts. The CA back cover provides an integrated pivot clevis, so pair it with a matching clevis pin for angular movement. If your mechanism must stay put during an air loss or valve centre, remember this cylinder will drift; add an external rod lock or pilot check valve, as the TPU bumpers only soften the end of travel and act as no brake. With a 70 mm stroke, keep the load guided to prevent rod side-loading and bending.
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 MI12X70SCA 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. The air port is M5x0.8.
No, the piston will drift if air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not act as a lock. For suspended loads, install an external rod lock or pilot-operated check valve.
