About the Airtac MI8~12 Stainless Steel Mini Cylinder MI10X85SU
Generating 39.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles an 85 mm stroke with a compact riveted construction. The Ø10 mm bore uses an M5x0.8 port and a Ø4 mm piston rod with an M4x0.7 male thread. Because the stainless barrel and rod resist mild corrosion, it outlasts painted-steel alternatives in damp or washdown-prone environments. The built-in magnet (-S) directly supports CMSG, DMSG and EMSG position switches.
For practical sizing, plan for a safe working load of about 24 N, which is roughly 60 percent of the 0.5 MPa push rating. Alternatively, it lifts about 2 kg vertically when applying a 2:1 safety margin to the 39.3 N output. Fixed TPU bumper pads absorb the impact at stroke extremes to protect the mechanism, while the U-style back cover provides a 90-degree port orientation for tight machinery layouts.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI10X85SU Is Used
PCB Depaneling Gate
Cycles an 85 mm stroke to open and close a lightweight routing gate on an electronics assembly line, utilizing the 39.3 N push force to clear small plastic dividers.
Label Applicator Tamp
Pushes a label applicator head forward onto small cartons, where the 2 kg vertical lift capacity and integrated magnet allow precise position confirmation before retraction.
Lab Sample Diversion
Actuates a 90-degree diversion flap inside a moisture-resistant stainless steel lab enclosure, routing fluid sample tubes to the correct testing carousel.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI10X85SU the Right Cylinder?
When sizing this 85 mm stroke unit, verify if the 39.3 N push at 0.5 MPa provides adequate thrust; stepping up to the Ø12 bore yields 56.5 N, whereas dropping to the Ø8 bore limits you to 25.1 N. The 85 mm travel is well within the 200 mm maximum standard stroke for this bore, so no made-to-order sizing is required. Remember that a plain double-acting cylinder drifts when air pressure is lost or the valve is centred, as the TPU pads only decelerate the end of stroke rather than locking the load; utilize an external pilot check valve if you must hold a vertical position. The U rear cover dictates a 90-degree mounting and porting orientation, and the included -S magnet enables solid-state or reed sensor tracking.
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 MI10X85SU FAQ
The Ø10 mm bore 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, with a theoretical maximum of 8 kgf at 1.0 MPa. It features an M5x0.8 air port and operates at speeds between 30 and 800 mm/s.
No, the piston will drift if air is lost or the valve is centred, as the fixed TPU bumper pads only decelerate the stroke end rather than acting as a brake. To maintain a vertical position, you must install an external rod lock or a pilot-operated check valve.
