Airtac MI8~12 Stainless Steel Mini Cylinder MI8X80SCA
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI8X80SCA is a genuine double acting round-body mini air cylinder with a Ø8mm bore and 80mm 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 MI8X80SCA
Generating 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation tasks. The Ø8 mm bore uses an M5x0.8 port and a 4 mm piston rod with an M4x0.7 male thread. Its stainless construction resists mild corrosion and washdown, offering an advantage over painted alternatives in damp environments. Built-in fixed TPU bumper pads absorb stroke-end impact.
Because it includes a piston magnet (-S), this model supports CMSG, DMSG and EMSG reed or electronic switches for position sensing. The CA rear cover provides a pivot or clevis mount, while the front and rear dimensions match the ISO 6432 mini-cylinder mounting interface for straightforward bracket integration. Plan for a safe working load of about 15 N, which means it lifts roughly 1.3 kg vertically with a 2:1 margin.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X80SCA Is Used
Electronic Component Sorting
Pushes lightweight PCBs or resistors on a conveyor with a safe 15 N working load, using the CA pivot to accommodate slight guide misalignments.
Lab Sample Diverting
Handles 1.3 kg vertical lifts of small fluid vials in damp laboratory environments, relying on the stainless steel barrel to resist mild corrosion.
Small Parts Ejection
Ejects plastic moulded trim from a die at 30-800 mm/s, where the fixed TPU bumpers quietly absorb the end-of-stroke impact without needing adjustment.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X80SCA the Right Cylinder?
When sizing this 8 mm bore, the next step up is the Ø12 bore, which increases push force to 56.5 N at 0.5 MPa; there is no smaller standard MI bore below 8 mm. The 80 mm stroke is well within the 150 mm maximum standard stroke for this size, keeping the unit compact. The CA pivot back cover suits angular load articulation, and the -S magnet enables sensor switching. If your process drops air pressure or centres the valve, the piston will drift; the TPU bumpers only decelerate the stroke end and do not act as a lock. Use an external pilot-operated check valve or rod lock to hold a suspended load safely.
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 MI8X80SCA 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. This 8 mm bore cylinder features an M5x0.8 air port.
No, a standard double-acting MI cylinder drifts when air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not function as a brake. You must add an external rod lock or pilot check valve to hold a suspended load.
