About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X250CA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust linear motion tasks. The 25 mm bore pairs a 10 mm piston rod with a 1/8" port and a CA pivot clevis, making it ideal for articulated mechanisms. Its stainless barrel and rod resist mild corrosion, outperforming painted alternatives in damp or washdown environments. Fixed TPU bumper pads absorb stroke-end impact without offering adjustable cushioning.
For practical sizing, plan for roughly 147 N of usable work at 0.5 MPa, which translates to safely lifting about 12.5 kg vertically. The 250 mm stroke falls well within the 500 mm standard limit. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches; order a -S variant if electronic sensing is required.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X250CA Is Used
Package Diverter Arm
Swings a sorting gate on a packaging line using the CA pivot clevis, relying on the 245.3 N push force to deflect heavy cartons at 0.5 MPa.
Pallet Lift Gate
Raises a lightweight access flap on a roller conveyor, safely lifting around 12.5 kg of gate weight through the 250 mm stroke.
Textile Loom Tensioner
Maintains tension on a yarn guide in a humid manufacturing environment, leveraging the stainless barrel to prevent mild corrosion.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X250CA the Right Cylinder?
When sizing this 25 mm bore, the neighbouring 20 mm unit provides 157.0 N of push at 0.5 MPa, while the larger 32 mm option yields 402.2 N. If your mechanism experiences air loss or the valve centres, the piston will drift; the fixed bumpers only decelerate the end of travel and act as neither a lock nor a brake. To suspend a load securely, integrate an external rod lock or a pilot-operated check valve. The built-in CA rear clevis suits pivoting assemblies, and you can adapt the body using LB foot, FA flange or TC trunnion hardware conforming to ISO 6432 mounting dimensions. At 250 mm of extension, ensure the rod end is guided to prevent side-loading and premature rod-bending stress.
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 MI25X250CA FAQ
The 1/8" port feeds a 25 mm bore that generates 245.3 N push and 206.1 N pull at 0.5 MPa, or 343.4 N push and 288.5 N pull at 0.7 MPa. The theoretical maximum force is 50 kgf at 1.0 MPa.
This specific SKU lacks a magnet, so it cannot accept CMSG, DMSG or EMSG switches; you need the -S variant for sensing. The body uses ISO 6432 mounting dimensions for standard mini-cylinder brackets, and the rear features a CA pivot clevis.
