The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI12X45CA is a genuine double acting round-body mini air cylinder with a Ø12mm bore and 45mm 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 12 mm bore double-acting actuator handles light-duty positioning with precision. The riveted stainless-steel barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp production areas. Its compact 45 mm stroke and M5x0.8 port make it highly practical for tight spaces.
Built to ISO 6432 mounting dimensions, the body drops directly into standard mini-cylinder brackets. It uses fixed TPU bumper pads to decelerate the piston at stroke ends rather than adjustable air cushions. For sizing moving masses, plan for roughly 34 N of actual work at 0.5 MPa, which means it can safely lift about 2.9 kg vertically against gravity.

| Max (@1.0 MPa) | 12 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

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.
Uses the 45 mm stroke to push small electronic components onto a test fixture with 56.5 N of force at 0.5 MPa.
Actuates a lightweight routing gate on a conveyor, relying on the CA pivot clevis to accommodate the arc of the swing.
Ejects vials from a carousel, where the stainless-steel rod provides necessary washdown resistance against mild chemical splashes.
If your task requires less force, the Ø8 bore provides 25.1 N of push at 0.5 MPa, while stepping up to the Ø16 bore yields 100.5 N for heavier mechanisms. This specific CA back cover features a rear pivot clevis, ideal for angular load alignment, and you can pair it with LB foot or TC trunnion brackets. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches.
Remember that a standard double-acting cylinder drifts if air pressure drops or the valve is centred; the TPU bumpers only soften the end-of-stroke impact and will not lock the load. To suspend a vertical weight safely, install an external pilot check valve or a dedicated rod lock.
Quick checklist
At 0.5 MPa it pushes 56.5 N and pulls 42.4 N; at 0.7 MPa it pushes 79.1 N and pulls 59.4 N. The theoretical maximum force is 11.5 kgf at 1.0 MPa. The air port is M5x0.8 and the male rod thread is M6x1.0.
No, this specific SKU does not have a magnet. You must select the -S variant (MI12X45CA-S) to use CMSG, DMSG or EMSG magnetic switches. The unit features a CA rear pivot clevis and conforms to ISO 6432 mounting dimensions.
