Airtac MI8~12 Stainless Steel Mini Cylinder MI8X75U
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI8X75U is a genuine double acting round-body mini air cylinder with a Ø8mm bore and 75mm 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 MI8X75U
Generating 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact actuation tasks. The 8 mm bore and 75 mm stroke run on an M5x0.8 port, while the U back cover provides a 90-degree mounting orientation for tight spaces. Its riveted stainless barrel and rod resist mild corrosion, outperforming painted alternatives in damp environments.
Designed for light-duty work, plan for roughly 15 N of actual work at 0.5 MPa to ensure reliable operation. This translates to lifting about 1.3 kg vertically with a safe 2:1 margin. Fixed TPU bumper pads absorb end-of-stroke impacts, and because this SKU lacks a magnet, it cannot accept position sensors without upgrading to the -S variant.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X75U Is Used
Micro-Clamp Actuation
Drives small pneumatic clamps in electronics assembly fixtures, providing 25.1 N of push force to secure delicate PCBs during soldering.
Lab Sample Diverting
Pivots a 90-degree U-cover lever to sort lightweight vials in diagnostic analyzers, benefiting from the stainless build in humid lab environments.
Small Part Ejection
Pushes tiny plastic components out of molding machines, using the 75 mm stroke and fixed TPU bumpers to decelerate the ejection cycle smoothly.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X75U the Right Cylinder?
When sizing this 8 mm bore, the MI8X75U is the smallest available option, so stepping up to the 10 mm bore (39.3 N push @0.5 MPa) is necessary if your load exceeds the safe working threshold. The U-style 90-degree rear cover simplifies side mounting, and standard ISO 6432 dimensions ensure compatibility with standard mini-cylinder brackets. Note that air pressure alone will not hold a load if the valve is centred or air is lost; the piston will drift, requiring an external pilot check valve for position holding.
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 MI8X75U FAQ
The 8 mm bore generates 25.1 N push and 18.8 N pull at 0.5 MPa, and 35.2 N push / 26.4 N pull at 0.7 MPa. The theoretical maximum force is 5.1 kgf at 1.0 MPa. It uses an M5x0.8 air port.
No, this specific SKU does not include a magnet, so CMSG, DMSG, or EMSG switches cannot be used. You must select the -S variant (with magnet) to enable position sensing.
