Airtac MI8~12 Stainless Steel Mini Cylinder MI8X95SU
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI8X95SU is a genuine double acting round-body mini air cylinder with a Ø8mm bore and 95mm 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 MI8X95SU
Delivering 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles compact actuation with a 95 mm stroke. The riveted round-body construction pairs a corrosion-resistant barrel and rod with fixed TPU bumper pads that absorb stroke-end impact. Because the bore is Ø8, it uses the ISO 6432 mounting interface, dropping directly into standard mini-cylinder brackets and clevises for straightforward design integration.
The built-in magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing, while the U back cover provides a 90-degree mounting orientation. For practical sizing, plan for roughly 15 N of real work at 0.5 MPa, which translates to lifting about 1.3 kg vertically with a 2:1 safety margin. Air connects via an M5x0.8 port, and the unit operates smoothly between 30 and 800 mm/s.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X95SU Is Used
PCB Pusher Ejection
Uses the 25.1 N push force at 0.5 MPa to nudge lightweight printed circuit boards out of an inspection fixture without marring the surface.
Lab Sample Diverting
Leverages the stainless-steel build and compact 8 mm round body to resist mild corrosion in damp laboratory environments while routing small vials.
Small Part Sorting Gate
Employs the 95 mm stroke and 90-degree U cover to pivot a sorting flap for small plastic mouldings on a high-speed conveyor line.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X95SU the Right Cylinder?
When sizing this 8 mm bore, the next step up is the Ø12 class, which jumps to 56.5 N push at 0.5 MPa; there is no smaller standard MI bore below 8 mm. If your mechanism must hold a vertical load when air is removed or the valve is centred, this cylinder will drift, as the TPU pads only decelerate the stroke end rather than locking the piston. You would need an external rod lock or a pilot-operated check valve to hold position securely.
The 95 mm stroke is well within the 150 mm maximum standard stroke for this bore, but at full extension the Ø4 rod is more susceptible to side-loading and bending, so ensure the load travels on a guided rail. The U rear cover dictates a 90-degree pivot mounting style, and the -S magnet is required if you intend to fit CMSG, DMSG or EMSG sensors.
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 MI8X95SU FAQ
This double-acting cylinder generates 25.1 N push and 18.8 N pull at 0.5 MPa, increasing to 35.2 N push and 26.4 N pull at 0.7 MPa. The theoretical maximum force is 5.1 kgf at 1.0 MPa. It features an M5x0.8 air port and a Ø4 mm piston rod with an M4x0.7 male thread.
Yes, the -S suffix denotes a built-in piston magnet designed for CMSG, DMSG and EMSG reed or electronic switches. The U back cover provides a 90-degree mounting interface, allowing the cylinder to pivot, and the Ø8 bore conforms to ISO 6432 mounting dimensions for standard mini brackets.
