Airtac MI8~12 Stainless Steel Mini Cylinder MI10X40SULB
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI10X40SULB is a genuine double acting round-body mini air cylinder with a Ø10mm bore and 40mm 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 MI10X40SULB
Generating 39.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation tasks with ease. The Ø10 mm bore uses an M5x0.8 air port and an M4x0.7 male rod thread, while the 40 mm stroke stays well within the 200 mm standard limit. A built-in piston magnet enables position sensing with CMSG, DMSG or EMSG switches.
The riveted stainless barrel and rod shrug off mild corrosion, outlasting painted alternatives in damp environments. Because the Ø10 mm bore conforms to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises. For practical sizing, plan for roughly 24 N of actual work at 0.5 MPa, which means it can lift about 2 kg vertically with a safe 2:1 margin. Fixed TPU bumper pads absorb the stroke-end impact, and the included U back cover provides a 90-degree port orientation.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI10X40SULB Is Used
Electronic Component Sorting
Pushes small electronic parts down a testing lane with a 40 mm stroke, lifting parts up to roughly 2 kg safely during vertical transfer.
Light Package Diverting
Diverts lightweight cardboard boxes on a packaging conveyor using 39.3 N of push force, with the LB foot mount holding the body rigid against side impacts.
Lab Sample Ejection
Ejects processed laboratory vials from a testing carousel, where the stainless steel construction resists humidity and chemical washdowns.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI10X40SULB the Right Cylinder?
When sizing this actuator, compare its 39.3 N push force at 0.5 MPa against the adjacent bores: the smaller Ø8 mm generates 25.1 N, while the larger Ø12 mm provides 56.5 N. This SKU includes an LB foot mount for secure base mounting and a U-type back cover for a 90-degree port exit. The integrated magnet (-S) is essential if your application requires CMSG, DMSG or EMSG electronic or reed switches.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the directional valve is centred; the TPU bumpers only decelerate the piston near the stroke ends and do not function as a braking lock. To suspend a load safely during an air loss event, install an external rod lock or a pilot-operated check valve in the pneumatic circuit.
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 MI10X40SULB FAQ
This double-acting cylinder delivers a push force of 39.3 N and a pull force of 33 N at 0.5 MPa. At 0.7 MPa, the push increases to 55 N and the pull to 46.1 N. The theoretical maximum force is 8 kgf at 1.0 MPa. The air port size is M5x0.8, determined by the Ø10 mm bore.
No, a standard double-acting cylinder will drift if air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the piston at the stroke end and do not act as a lock. To maintain a vertical load, you must add an external rod lock or a pilot-operated check valve.
