About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X325SCA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles substantial work within a compact riveted round-body format. The Ø25 bore uses a 1/8" port and an M10x1.25 male rod thread. Because the piston carries a magnet, you can directly mount CMSG, DMSG or EMSG reed and electronic switches for position sensing.
The stainless barrel and rod resist mild corrosion, giving a real advantage over painted alternatives in damp or washdown settings. At 0.5 MPa, plan for roughly 147 N of actual work, which means it can vertically lift about 12.5 kg with a 2:1 safety margin. Fixed TPU bumper pads absorb the impact at stroke extremes, and the rear CA pivot cover simplifies clevis mounting.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X325SCA Is Used
Package Diverter Gate
Swings a routing flap on a packaging line, using the 325 mm stroke to clear large cartons while the stainless body shrugs off humid washdown environments.
Textile Loom Tensioner
Shifts a yarn guide bar back and forth, relying on the 245.3 N push force at 0.5 MPa to maintain steady material tension during high-speed production.
Pallet Stacking Pusher
Advances small cardboard components toward a stacking head, where the CA rear pivot absorbs angular misalignment during the 325 mm extension.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X325SCA the Right Cylinder?
If 245.3 N at 0.5 MPa is excessive, the Ø20 bore provides 157.0 N; if your application requires more power, stepping up to the Ø32 yields 402.2 N. This 325 mm stroke sits well within the 500 mm maximum, though the extended length means you should watch for rod bending under side loads. The ISO 6432 mounting interface ensures compatibility with standard mini-cylinder brackets.
Remember that venting the air or centering the valve causes the piston to drift, as the TPU bumpers only decelerate the end of travel rather than locking the rod. To suspend a load safely, install an external rod lock or a pilot-operated check valve.
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 MI25X325SCA FAQ
This Ø25 bore cylinder features a 1/8" port. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, with a theoretical maximum of 50 kgf at 1.0 MPa.
Yes, the built-in magnet allows CMSG, DMSG and EMSG switches. The CA rear cover provides a pivot clevis for articulated mounting. Note that fixed TPU bumpers decelerate the stroke end but do not lock the rod.
