Airtac MI8~12 Stainless Steel Mini Cylinder MI8X75CALB
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI8X75CALB 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 MI8X75CALB
Delivering 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact actuation tasks. The Ø8 mm bore uses an M5x0.8 air port and a Ø4 mm piston rod with an M4x0.7 male thread. Its stainless barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Fixed TPU bumper pads absorb the impact at stroke extremes, decelerating the motion smoothly.
Because it conforms to ISO 6432 mounting dimensions, the body drops directly into standard mini-cylinder brackets and clevises. Plan for roughly 15 N of actual work at 0.5 MPa to maintain a safe margin. This translates to lifting about 1.3 kg vertically, letting you match the cylinder to real part weights. The included LB foot mount and CA rear pivot cover supply rigid and articulated mounting options.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X75CALB Is Used
Micro-clip insertion
Pushes delicate wire clips into PCB assemblies using the 25.1 N output, where the stainless body resists flux fumes.
Bin gate actuation
Opens and closes lightweight gravity-fed dispenser flaps for small electronic components in a dry storage facility.
Lab sample diverter
Pivots a small guide chute to route test tubes, lifting roughly 1.3 kg safely with the LB foot mount stabilising the body.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X75CALB the Right Cylinder?
When sizing this 8 mm bore, stepping up to the Ø10 bore raises the 0.5 MPa push force to 39.3 N, while the Ø8 is the smallest available option in the MI family. If your mechanism loses air or the valve centres, the piston will drift, as the TPU bumpers only soften the stroke end rather than locking the rod. To suspend a load securely, specify an external rod lock or a pilot-operated check valve. The 75 mm stroke sits well within the 150 mm standard limit, though long, thin rods are vulnerable to side-loading, so keep the load guided axially to prevent bending. Note that this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG or EMSG switches without switching to the -S variant.
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 MI8X75CALB FAQ
At 0.5 MPa it provides 25.1 N push and 18.8 N pull. At 0.7 MPa it provides 35.2 N push and 26.4 N pull. The theoretical maximum force is 5.1 kgf at 1.0 MPa. The air port is M5x0.8.
No, this SKU does not include a magnet. To use CMSG, DMSG or EMSG switches, you must select the -S variant. The cylinder uses an ISO 6432 mounting interface and fixed TPU bumper pads rather than an adjustable air cushion.
