About the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X90CA
Generating 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact actuation tasks. The Ø12 mm bore operates on an M5x0.8 air port and features a CA rear pivot cover for clevis mounting. Its stainless barrel and rod resist mild corrosion, making it superior to painted alternatives in damp or washdown environments. Built to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets.
Fixed TPU bumper pads absorb impact at the stroke ends, though they do not provide adjustable cushioning. For practical sizing, plan for roughly 34 N of actual work at 0.5 MPa, which translates to lifting about 2.9 kg vertically with a safe 2:1 margin. Because this SKU lacks the -S suffix, it has no magnet and cannot host CMSG, DMSG or EMSG sensors.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X90CA Is Used
PCB Depaneling Gate
Cycles a lightweight routing gate to separate printed circuit boards, utilizing the 56.5 N push force to cleanly shear frangible connections.
Carton Flap Folder
Swings a small mechanical arm via the CA pivot bracket to tuck minor flaps on small packaging lines before tape application.
Lab Reagent Dispenser
Actuates a 2.9 kg fluid valve vertically in damp laboratory environments, relying on the stainless steel rod to resist mild chemical corrosion.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X90CA the Right Cylinder?
When sizing this 90 mm stroke actuator, compare it against adjacent bores: the smaller Ø10 generates 39.3 N push, while the larger Ø16 provides 100.5 N at 0.5 MPa. The CA rear clevis is ideal for pivoting loads, but remember that a plain cylinder drifts if air pressure drops or the valve is centered—the bumpers only decelerate the end of travel and act as neither a lock nor a brake. To hold a vertical load securely, install an external rod lock or a pilot-operated check valve.
At 90 mm, the stroke is well within the 250 mm maximum for this bore, but side loads can still bend the Ø6 mm rod. Ensure the front pivot allows proper alignment to prevent premature seal wear.
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 MI12X90CA FAQ
This Ø12 mm bore cylinder features an M5x0.8 port and a Ø6 mm rod. It generates 56.5 N push and 42.4 N pull at 0.5 MPa, increasing to 79.1 N push and 59.4 N pull at 0.7 MPa. The theoretical maximum force is 11.5 kgf at 1.0 MPa.
No, because this specific SKU lacks the -S suffix, it has no internal magnet and cannot support CMSG, DMSG or EMSG switches. You would need the MI12X90CA-S variant for magnetic sensing. It uses ISO 6432 mounting dimensions and fixed TPU bumper pads rather than adjustable air cushions.
