Airtac MI8~12 Stainless Steel Mini Cylinder MI8X5SCA
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI8X5SCA is a genuine double acting round-body mini air cylinder with a Ø8mm 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 MI8X5SCA
Delivering 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles tiny 5 mm strokes with precision. The riveted round body shrinks footprint while resisting mild corrosion in damp environments. An M5x0.8 port feeds the Ø4 mm rod, and the built-in magnet (-S) supports CMSG, DMSG or EMSG sensors for position confirmation.
Because the 25.1 N rating is theoretical, plan for a real working load of about 15 N at 0.5 MPa. Vertically, it lifts roughly 1.3 kg safely with a 2:1 margin. Fixed TPU bumper pads absorb the stroke-end impact, and the CA rear clevis allows pivoting mounts. It conforms to ISO 6432 mounting dimensions for easy bracket integration.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X5SCA Is Used
Micro-Part Ejection
Uses the 5 mm stroke to push tiny electronic components out of machining fixtures without overshooting, relying on the 15 N safe working load.
Small Part Sorting
Diverts lightweight plastic caps on a conveyor using the integrated magnet for position feedback and the CA clevis for angled mounting.
Lab Sample Clamping
Holds delicate glass vials during testing where the stainless steel body withstands routine wipe-downs and mild chemical splashes.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X5SCA the Right Cylinder?
Choose this Ø8 bore when the next size up (Ø10, 39.3 N push @0.5 MPa) is excessive, as there is no smaller AirTAC MI series. The 5 mm stroke is ideal for micro-clamping or ejecting tiny parts. If your process loses air, this cylinder will drift and drop the load—the TPU bumpers only decelerate the end of travel, so add a pilot check valve if you need to hold position vertically.
The CA back cover suits pivoting linkages, while the -S magnet enables electronic or reed switching. For higher cycle speeds requiring adjustable air cushioning, step up to the MIC variant instead of relying on the fixed MI bumpers.
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 MI8X5SCA FAQ
At 0.5 MPa it pushes 25.1 N and pulls 18.8 N. At 0.7 MPa it pushes 35.2 N and pulls 26.4 N. The theoretical maximum force is 5.1 kgf at 1.0 MPa. It uses an M5x0.8 air port and a Ø4 mm piston rod.
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 do not act as a brake. You must use an external rod lock or pilot check valve to hold a suspended load.
