Airtac MI8~12 Stainless Steel Mini Cylinder MI8X50CA
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI8X50CA is a genuine double acting round-body mini air cylinder with a Ø8mm bore and 50mm 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 MI8X50CA
Generating 25.1 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles precise 50 mm strokes. The Ø8 mm bore uses an M5x0.8 port and a 4 mm piston rod with an M4x0.7 male thread. Its stainless barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Fixed TPU bumper pads absorb the impact at stroke extremes without adding bulk.
Because it conforms to ISO 6432 mounting dimensions, the body drops directly into standard mini-cylinder brackets. For real-world sizing, plan for about 15 N of actual work at 0.5 MPa rather than the absolute maximum. This translates to lifting roughly 1.3 kg vertically with a safe 2:1 margin, letting you match the cylinder to precise part weights.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X50CA Is Used
Micro-actuation in electronics assembly
Drives delicate 50 mm pick-and-place movements for small circuit board components where a 15 N working load prevents crushing fragile parts.
Lab automation sample routing
Indexes tiny test vials between analysis stations, with the stainless build resisting humidity and the CA clevis allowing pivoting articulation.
Lightweight product sorting
Pushes lightweight plastic closures off a conveyor belt, easily handling items under the 1.3 kg vertical lift threshold at 0.5 MPa.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X50CA the Right Cylinder?
As the smallest bore in the range, the MI8X50CA sits at the bottom of the scale, so if your task needs more power you step up to the Ø10 bore which provides 39.3 N of push at 0.5 MPa. The rear CA pivot clevis accommodates angular misalignment during the stroke extension. Note that this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG or EMSG sensors; you must specify the -S variant for position detection. Furthermore, the fixed bumpers only decelerate the end of travel and will not hold the load if air pressure drops, so add a pilot check valve for vertical positioning.
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 MI8X50CA FAQ
At 0.5 MPa it provides 25.1 N push and 18.8 N pull. At 0.7 MPa it provides 35.2 N push and 26.4 N pull. The theoretical maximum force is 5.1 kgf at 1.0 MPa. The air port is M5x0.8.
Yes, the Ø8 mm body uses the ISO 6432 mounting interface for standard clevis and bracket compatibility. However, this specific SKU has no internal magnet, so it cannot accept CMSG, DMSG or EMSG switches; order an -S variant for sensing.
