The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI12X115SU is a genuine double acting round-body mini air cylinder with a Ø12mm bore and 115mm 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.
Generating 56.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles a 115 mm stroke with a compact riveted round body. The integrated piston magnet supports CMSG, DMSG and EMSG sensors for position feedback, while the rear U cover provides a 90-degree port and mounting orientation for tight spaces. A 12 mm bore yields a practical safe working load of roughly 34 N, letting you lift about 2.9 kg vertically with a 2:1 safety margin.
Built to ISO 6432 mounting dimensions, the unit drops directly into standard mini-cylinder brackets and clevises. The stainless barrel and rod resist mild corrosion and washdown better than painted alternatives. Fixed TPU bumper pads absorb stroke-end impact across the 30-800 mm/s speed range, and the M5x0.8 port matches the bore size exactly.

MI-family variants: MI / MIC (double acting ±cushion), MSI / MTI (single acting push / pull), MID / MICD (double rod ±cushion), MIJ / MICJ (adjustable stroke ±cushion). Back covers CA / U / R / CM. Mounting LB / FA / SDB / TC.
Drives a 115 mm stroke to push light electronic parts into sockets on an assembly line, utilizing the 56.5 N push force for precise, low-impact insertion.
Actuates a 90-degree routing gate on a conveyor, relying on the U cover for compact side mounting and the stainless body for dusty industrial environments.
Folds light cardboard flaps on a packaging machine, where the 2.9 kg vertical lift capacity easily handles the flap weight and the TPU bumpers prevent denting.
When sizing this 12 mm bore, compare it against neighbours: the 10 mm version offers 39.3 N push at 0.5 MPa, while the 16 mm steps up to 100.5 N. This model sits perfectly in the middle for light-duty tasks. If your application requires the rod to stay put during air loss or valve centering, note that this standard cylinder will drift; add an external rod lock or pilot-operated check valve for secure load holding.
The 115 mm stroke is well within the 250 mm maximum for this bore, but at full extension you should still minimize side-loading to prevent rod bending. The U-style back cover dictates a 90-degree rear orientation, and the included -S magnet ensures compatibility with reed and electronic switches.
Quick checklist
At 0.5 MPa it provides 56.5 N push and 42.4 N pull. At 0.7 MPa it provides 79.1 N push and 59.4 N pull. The theoretical maximum force is 11.5 kgf at 1.0 MPa. The air port is M5x0.8.
No, it features fixed TPU bumper pads that decelerate the stroke end but do not offer adjustable air cushioning. Additionally, it will not hold a load if air is lost; use an external rod lock or pilot check valve for holding.
