Airtac MI8~12 Stainless Steel Mini Cylinder MI8X150CA
The AirTAC Airtac MI8~12 Stainless Steel Mini Cylinder MI8X150CA is a genuine double acting round-body mini air cylinder with a Ø8mm bore and 150mm 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 MI8X150CA
Delivering 25.1 N of push force at 0.5 MPa, the AirTAC MI8X150CA is a compact double-acting round-body mini cylinder built for tight spaces. Its stainless-steel barrel and Ø4 mm rod shrug off mild corrosion, giving it a real edge over painted-steel alternatives in damp or washdown-prone environments. The riveted construction keeps the unit light, while fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning.
Because this 8 mm bore unit lacks the -S suffix, it cannot host a magnetic sensor; order an -S variant if you need CMSG, DMSG or EMSG switches. Operating at 30-800 mm/s on an M5x0.8 port, it provides a safe working load of roughly 15 N. That translates to lifting about 1.3 kg vertically with a 2:1 safety margin, letting you match it precisely to light part weights.

Where the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X150CA Is Used
Electronic Component Ejection
Uses the 25.1 N push stroke to tap delicate PCBs out of test fixtures without marring surfaces, relying on the stainless body for flux-fume humidity resistance.
Small Parts Diversion
Pivots via the CA clevis to deflect lightweight plastic caps on a packaging line, safely moving parts well within the 15 N safe working load.
Lab Sample Pusher
Advances microscope slides into viewing position with a 150 mm travel, where the compact riveted body fits easily inside crowded test enclosures.
Is the Airtac MI8~12 Stainless Steel Mini Cylinder MI8X150CA the Right Cylinder?
Choosing this 150 mm stroke model means you are working at the maximum standard stroke limit for an Ø8 bore. If your task needs even less force, there is no smaller MI bore available, so you would need to look outside the series. Stepping up to a Ø10 bore increases the 0.5 MPa push force to 39.3 N. The CA rear pivot cover suits clevis mounting, but remember a plain cylinder drifts if air pressure drops—the TPU bumpers only soften the end of travel, so fit an external pilot check valve if you must hold a load vertically. At full extension, ensure your side-load geometry is sound to avoid bending the 4 mm rod.
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 MI8X150CA FAQ
This 8 mm bore cylinder features an M5x0.8 port and generates 25.1 N push / 18.8 N pull at 0.5 MPa, and 35.2 N push / 26.4 N pull at 0.7 MPa. Its theoretical maximum force is 5.1 kgf at 1.0 MPa.
Yes, the Ø8 bore uses the ISO 6432 mini-cylinder mounting interface, so it drops directly into standard clevis and foot brackets. However, because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG magnetic switches.
