About the Airtac MI8~12 Stainless Steel Mini Cylinder MI10X40U
Delivering 39.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact actuation where space is tight. The Ø10 mm bore uses an M5x0.8 port and a 40 mm stroke, making it ideal for light-duty sorting tasks. Because the stainless barrel and rod resist mild corrosion, it outlasts painted alternatives in damp or washdown environments.
Built with fixed TPU bumper pads to decelerate the stroke end, the riveted body remains light and compact. It features a 90-degree U back cover for specific mounting orientations. For actual work, plan for roughly 24 N of safe load at 0.5 MPa, which means it can lift about 2 kg vertically with a 2:1 safety margin. This SKU lacks a magnet, so it cannot accept position sensors.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI10X40U Is Used
Package Sorting Diverter
Pushes small lightweight cardboard cartons on a packaging line using its 39.3 N push force, while the stainless body handles occasional moisture.
Lab Sample Ejector
Ejects plastic test tube racks from a testing carousel with a 40 mm stroke, lifting about 2 kg safely with a 2:1 margin.
Small Part Clamp
Clamps thin sheet metal brackets during a light machining process, utilising the 90-degree U cover for a compact perpendicular mount.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI10X40U the Right Cylinder?
When sizing this 10 mm bore, compare it against the neighbouring 8 mm bore (25.1 N push @0.5 MPa) for lighter tasks, or step up to the 12 mm bore (56.5 N push @0.5 MPa) if you need more power. The U back cover provides a 90-degree mounting orientation, and the body conforms to ISO 6432 mini-cylinder mounting dimensions for standard brackets. If your application needs position confirmation, select the -S magnet version to enable CMSG, DMSG or EMSG switches.
Remember that a plain double-acting cylinder drifts when air is lost or the valve is centred; the TPU bumpers only soften the impact at stroke end and do not act as a brake. To hold a vertical load securely, install an external rod lock or a pilot-operated check valve. The 40 mm stroke is well within the 200 mm maximum, keeping rod bending stress minimal.
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 MI10X40U FAQ
The 10 mm bore provides a push force of 39.3 N and a pull force of 33 N at 0.5 MPa. At 0.7 MPa, push is 55 N and pull is 46.1 N. The theoretical maximum force is 8 kgf at 1.0 MPa. It uses an M5x0.8 air port.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG or EMSG switches. You must select the -S variant (MI10X40U-S) if you require position sensing.
