About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X180CA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles substantial work within a compact footprint. The riveted stainless barrel and Ø10 mm rod naturally resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Because it lacks the -S suffix, this specific SKU cannot host a magnetic sensor; you would need the -S variant to use CMSG, DMSG or EMSG switches.
At 0.5 MPa you can plan for roughly 147 N of actual work, which translates to lifting a 12.5 kg mass vertically with a safe 2:1 margin. The 180 mm stroke is well within the 500 mm maximum for this bore, and the rear CA pivot cover allows straightforward clevis mounting. Fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X180CA Is Used
Package Diverter Arm
Uses the CA clevis to pivot a gating arm on a packaging line, relying on the 245.3 N thrust to push heavy cartons laterally at 0.5 MPa.
Lab Washdown Station
The stainless steel construction survives mildly corrosive damp environments, actuating a rinse cover over 180 mm without rusting.
Textile Loom Tensioner
Provides consistent pulling force of 206.1 N at 0.5 MPa to maintain fabric tension, with TPU pads softening the rapid stroke ends.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X180CA the Right Cylinder?
When sizing this 25 mm bore, stepping down to a 20 mm cylinder drops the 0.5 MPa push force to 157.0 N, while moving up to a 32 mm bore raises it to 402.2 N. This model occupies a strong middle ground for moderate loads. The CA rear pivot cover is ideal for articulating mechanisms, and standard LB foot, FA flange, SDB pivot, and TC trunnion brackets fit the ISO 6432 mounting dimensions.
Remember that venting the air causes the piston to drift, as the fixed bumpers only decelerate the end of travel rather than locking the rod. To suspend a load safely, integrate an external rod lock or a pilot-operated check valve. Furthermore, the 180 mm stroke demands careful alignment to prevent rod bending under side loads.
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 MI25~40 Stainless Steel Mini Cylinder MI25X180CA FAQ
This 25 mm bore cylinder features a 1/8" air port and an M10x1.25 male rod thread. The double-acting thrust is 245.3 N push and 206.1 N pull at 0.5 MPa, increasing to 343.4 N push and 288.5 N pull at 0.7 MPa. The theoretical maximum force is 50 kgf at 1.0 MPa.
No, because this SKU lacks the -S suffix it does not contain a piston magnet and cannot accept CMSG, DMSG or EMSG switches. You must select the -S magnet variant for position sensing. It uses the ISO 6432 mounting interface and includes a CA rear clevis cover for pivoting mounts.
