About the Airtac MI8~12 Stainless Steel Mini Cylinder MI10X55U
Delivering 39.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact actuation with ease. The 10 mm bore features an M5x0.8 port and a 55 mm stroke, utilizing a 90-degree U rear cover for space-saving lateral mounting. Its stainless barrel and piston rod naturally resist mild corrosion, outperforming painted alternatives in damp or washdown settings.
Built with fixed TPU bumper pads to soften stroke-end impact, the riveted body remains light and durable. Because this specific SKU lacks the -S magnet option, it cannot accept CMSG, DMSG or EMSG position sensors. For practical sizing, plan for a safe working load of roughly 24 N, which means it can vertically lift about 2 kg with a 2:1 safety margin.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI10X55U Is Used
PCB Ejector Pins
Uses the 39.3 N push force to pop bare circuit boards from test fixtures without marring the surface, fitting neatly into tight electronics assembly machinery.
Small Pouch Flap Folding
Employs the 55 mm stroke to tuck closure flaps on compact sachet packaging lines, where the 90-degree U cover allows mounting parallel to the conveyor belt.
Lab Sample Diverting
Pushes lightweight guide rails to reroute vial traffic at analytical stations, leveraging the stainless steel construction for wipe-down hygiene in clinical environments.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI10X55U the Right Cylinder?
When sizing this actuator, compare it against its neighbors: the smaller Ø8 bore provides 25.1 N of push at 0.5 MPa, while the larger Ø12 bore offers 56.5 N, giving you clear scaling steps if your 39.3 N requirement shifts. The 55 mm stroke is well within the 200 mm maximum standard stroke for this bore, ensuring standard availability. The 90-degree U back cover dictates your port and pivot orientation, so verify your manifold layout matches this geometry.
Keep in mind that a plain double-acting cylinder like this will drift if air pressure is lost or the directional valve is centered; the TPU bumpers only decelerate the piston near the stroke end and do not function as a locking brake. To suspend a load safely mid-stroke, integrate an external pilot-operated check valve or a dedicated rod lock.
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 MI10X55U FAQ
This 10 mm bore cylinder features an M5x0.8 port. It generates 39.3 N push and 33 N pull at 0.5 MPa, increasing to 55 N push and 46.1 N pull at 0.7 MPa. The theoretical maximum force is 8 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for position sensing. It uses the ISO 6432 mounting interface and fixed TPU bumper pads rather than an adjustable air cushion.
