About the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X10U
Delivering 25.1 N of push force at 0.5 MPa, the AirTAC MI8X10U is a compact double-acting round-body mini cylinder built for tight spaces. Its stainless-steel barrel and piston rod shrug off mild corrosion, giving it a real edge over painted-steel alternatives in damp or washdown-prone environments. The riveted construction keeps the body light, while fixed TPU bumper pads absorb the impact at stroke ends to protect your mechanism. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches.
For practical sizing, plan for a safe working load of roughly 15 N rather than the absolute maximum rating. This translates to lifting about 1.3 kg vertically with a 2:1 safety margin, making it ideal for moving very light components. The cylinder features an M5x0.8 port, an M4x0.7 male rod thread, and a U-type back cover that orients the air supply at 90 degrees for neat routing in confined enclosures.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X10U Is Used
Micro-clip insertion
Pushes delicate 1.3 kg plastic clips into electronic PCB assemblies using the 10 mm stroke, where the compact U-cover keeps the manifold plumbing flush against the machine frame.
Lab vial indexing
Advances lightweight glass vials in a diagnostic carousel, leveraging the stainless-steel rod to resist humidity and chemical vapours without surface degradation.
Tiny part ejection
Kicks small rubber gaskets out of a stamping die, relying on the fixed TPU bumper pads to silently absorb the 10 mm end-of-stroke impact without bouncing the part.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X10U the Right Cylinder?
When sizing this Ø8 bore, stepping up to the Ø12 model increases the 0.5 MPa push force to 56.5 N if your 15 N safe working load proves insufficient. As the smallest bore in the MI family, there is no smaller standard option, so this is your baseline for ultra-light tasks. The U-type back cover simplifies side-port plumbing, and because this specific SKU has no internal magnet, you must select an -S variant if your sequence requires CMSG or DMSG sensor feedback. Furthermore, a plain double-acting cylinder drifts when air is lost or a valve is centred; the bumper pads only decelerate the stroke end and will not lock the load. Use a pilot-operated check valve for position holding.
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 MI8X10U FAQ
The Ø8 bore generates 25.1 N push and 18.8 N pull at 0.5 MPa, increasing to 35.2 N push and 26.4 N pull at 0.7 MPa. The theoretical maximum force is 5.1 kgf at 1.0 MPa. It uses an M5x0.8 air port and a 4 mm piston rod with an M4x0.7 male thread.
It conforms to ISO 6432 mounting dimensions for easy bracket integration, but this specific SKU lacks a magnet and cannot host CMSG, DMSG or EMSG switches. You must specify an -S variant for sensing capabilities. It also features a U-type back cover for 90-degree port orientation.
