About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X80SCA
Delivering 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation with ease. The 12 mm bore and 80 mm stroke rely on an M5x0.8 air port, while the integrated piston magnet allows direct mounting of CMSG, DMSG or EMSG reed and electronic switches for precise end-of-stroke detection. Its CA rear pivot cover supplies a robust clevis joint for articulated rod-end loads.
The rolled stainless barrel and rod shrug off mild corrosion, outperforming painted alternatives in damp production areas. Fixed TPU bumper pads absorb the impact at stroke extremes, decelerating the piston without the complexity of adjustable cushioning. For practical sizing, plan for roughly 34 N of usable work at 0.5 MPa, which translates to lifting about 2.9 kg vertically with a safe 2:1 margin.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X80SCA Is Used
Electronic Component Sorting
Actuates small diverter gates on PCB assembly lines, using the 56.5 N push force to flick lightweight plastic trays into inspection lanes.
Blister Pack Sealing
Drives an 80 mm stroke pressing head to close thin film over pharmaceutical blister packs, where the CA clevis accommodates slight guide misalignment.
Lab Sample Ejection
Pushes filled test-tube racks out of a centrifuge loading dock, benefiting from the stainless build to resist humid laboratory environments.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X80SCA the Right Cylinder?
When sizing this 12 mm bore unit against its neighbours, the smaller Ø8 generates 25.1 N of push at 0.5 MPa, whereas the larger Ø16 offers 100.5 N, giving you clear stepping stones if your payload shifts. The 80 mm stroke sits well below the 250 mm maximum standard travel, keeping rod bending stress low. Because the CA pivot cover accommodates angular movement, ensure your linkage geometry prevents side-loading the rod. If your process requires the piston to stay put during a compressed-air failure or when a valve is centred, note that this cylinder will drift; the bumpers only soften the end of travel and act as neither a brake nor a lock. You must fit an external rod lock or a pilot-operated check valve 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 MI12X80SCA FAQ
This 12 mm bore cylinder features an M5x0.8 air port and generates 56.5 N push / 42.4 N pull at 0.5 MPa, and 79.1 N push / 59.4 N pull at 0.7 MPa. The theoretical maximum force is 11.5 kgf at 1.0 MPa.
Yes, the Ø12 bore uses the ISO 6432 mini-cylinder mounting interface, so it drops directly into standard mini brackets and clevises. The -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG or EMSG switches for position sensing.
