About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X40CA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles substantial work in a compact footprint. The Ø25 mm bore uses a 1/8" port and an M10x1.25 male rod thread. Its riveted stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Because it follows ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises.
For practical sizing, plan for about 147 N of real work at 0.5 MPa, which means it lifts roughly 12.5 kg vertically with a 2:1 safety margin. The rear CA pivot cover suits articulated rod-end linkages. Fixed TPU bumper pads absorb stroke-end impact, though this SKU lacks a magnet and cannot host CMSG, DMSG or EMSG sensors.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X40CA Is Used
Pivot Diverter Gate
Leverages the CA rear clevis to swing a heavy sorting flap on a packaging line, utilising the 245.3 N push force to deflect parcels reliably.
Washdown Clamp
Holds stainless-steel fixtures in a food-grade washdown bay, where the riveted stainless barrel shrugs off mild moisture and cleaning spray.
Pallet Stopper Arm
Extends 40 mm to halt pallets on a gravity roller conveyor, absorbing the impact via fixed TPU pads instead of transferring shock to the frame.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X40CA the Right Cylinder?
When sizing this 245.3 N (0.5 MPa) unit, the smaller Ø20 bore provides 157.0 N, while the larger Ø32 bore offers 402.2 N if your payload demands more push. The 40 mm stroke is short and highly resistant to rod buckling, but if you scale up the travel toward the 500 mm maximum, ensure a front pivot or guide to prevent side-loading damage. This CA clevis model articulates naturally to absorb misalignment.
Remember that venting the air supply causes the piston to drift, as the TPU bumpers only decelerate the end of stroke and act as neither a lock nor a brake. To suspend a vertical load safely during an air loss event, fit an external rod lock or a pilot-operated check valve. Additionally, because this specific SKU lacks the -S magnet, position sensing is impossible without upgrading to the magnet-equipped variant.
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 MI25X40CA FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N. At 0.7 MPa it pushes 343.4 N and pulls 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa. Air connects via a 1/8" port, and the piston rod is Ø10 mm with an M10x1.25 male thread.
Yes, the Ø25 bore adheres to ISO 6432 mounting dimensions, so it fits standard mini-cylinder clevises and brackets. However, this specific SKU has no internal magnet, meaning it cannot accept CMSG, DMSG or EMSG magnetic switches; you would need the -S variant for position sensing.
