Airtac MI8~12 Stainless Steel Mini Cylinder MI12X5CA
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI12X5CA is a genuine double acting round-body mini air cylinder with a Ø12mm bore and 5mm 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 MI12X5CA
Delivering 56.5 N of push force at 0.5 MPa, this stainless-steel round-body mini cylinder handles short 5 mm strokes with a compact riveted build. The Ø12 mm bore operates on an M5x0.8 air port and conforms to ISO 6432 mounting dimensions, dropping directly into standard mini-cylinder brackets. Its CA rear pivot cover is built specifically for clevis mounting, accommodating articulating rod-end loads.
Because the stroke is so brief, the fixed TPU bumper pads easily absorb the end-of-travel impact without needing adjustable cushioning. Plan for a real work load of about 34 N, which lets you lift roughly 2.9 kg vertically with a safe 2:1 margin. Note that this specific SKU lacks the -S magnet, so it cannot host CMSG, DMSG or EMSG sensors; you would need the magnet-equipped variant for position detection.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X5CA Is Used
Micro-Clamping
Holds small electronic components during ultrasonic welding using the 5 mm stroke and 56.5 N push force.
Part Ejection
Pushes lightweight molded plastic parts out of a machining fixture with a quick 5 mm tap.
Valve Actuation
Trips a mechanical limit or pneumatic pilot valve in a tight control panel via the CA pivot mount.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI12X5CA the Right Cylinder?
When sizing this actuator, the 56.5 N push at 0.5 MPa sits between the smaller Ø8 bore (25.1 N) and the larger Ø16 bore (100.5 N), making it ideal for light-duty clamping or ejecting. The 5 mm movement is highly specialized for micro-displacement tasks rather than general transfer. If your process loses air or the valve centers, the piston will drift and drop the load—the TPU pads only decelerate the stroke end, so add an external pilot check valve if you need to hold vertical position. The CA clevis back cover pairs with the fixed front nose for pivot mounting, and you can swap in LB foot or FA flange brackets if rigid anchoring is preferred.
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 MI12X5CA FAQ
The Ø12 mm bore has an M5x0.8 port. It generates 56.5 N push and 42.4 N pull at 0.5 MPa, 79.1 N push and 59.4 N pull at 0.7 MPa, with a theoretical maximum of 11.5 kgf at 1.0 MPa.
No, this specific SKU lacks the internal magnet required for switches. You must select the -S variant to use CMSG, DMSG or EMSG sensors. The unit uses fixed TPU bumper pads rather than an adjustable air cushion.
