About the Airtac MI8~12 Stainless Steel Mini Cylinder MI10X40SU
Delivering 39.3 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact actuation where mild corrosion or washdown resistance is required. The riveted round body relies on fixed TPU bumper pads to decelerate the stroke end, keeping the unit compact while operating at 30-800 mm/s. Because the bore is Ø10, the air port is M5x0.8 and the male rod thread is M4x0.7.
Designed to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises. This SKU includes a piston magnet for CMSG, DMSG or EMSG switches, and features a U-type back cover that orients the port 90 degrees for tight routing. Plan for roughly 24 N of actual work at 0.5 MPa, which means it lifts about 2 kg vertically with a safe 2:1 margin.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI10X40SU Is Used
PCB Pusher
Indexes bare circuit boards laterally on a conveyor with a 40 mm stroke, using the 39.3 N push force to nudge lightweight panels without marring them.
Lab Dispenser
Actuates a small fluid valve on an automated test bench, where the stainless rod resists chemical splashes and the 90-degree U cover keeps air lines tidy.
Parts Diverter
Pushes small plastic fasteners down a sorting chute at 2 kg of vertical lift capacity, relying on the built-in magnet to confirm retraction via a DMSG switch.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI10X40SU the Right Cylinder?
When sizing this 10 mm bore, compare it against its neighbours: an 8 mm bore yields 25.1 N of push at 0.5 MPa, while stepping up to a 12 mm bore provides 56.5 N. If your application loses air or the valve is centred, the piston will drift, as the TPU bumpers only soften the end of stroke rather than locking the load; add an external rod lock or pilot check valve if you need to hold position. The 40 mm stroke is well within the 200 mm maximum standard stroke for this bore, minimising rod-bending side-load risks. Ensure you pair the built-in magnet with a CMSG, DMSG or EMSG sensor, and utilise the 90-degree U rear cover alongside LB foot or FA flange mounts for your layout.
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 MI10X40SU FAQ
At 0.5 MPa it provides 39.3 N push and 33 N pull. At 0.7 MPa it provides 55 N push and 46.1 N pull. The theoretical maximum force is 8 kgf at 1.0 MPa. The air port is M5x0.8 and the male rod thread is M4x0.7.
It operates at 30-800 mm/s, but uses fixed TPU bumper pads to decelerate the stroke end rather than an adjustable air cushion. It does not hold position on air loss; the piston drifts, so install an external rod lock or pilot check valve for holding. The -S magnet allows CMSG, DMSG and EMSG switches for sensing.
