About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X225CA
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 Ø25 mm bore uses a 1/8" port and an M10x1.25 male rod thread, extending 225 mm on demand. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Built-in fixed TPU bumper pads decelerate the piston at stroke end to reduce impact wear.
For practical sizing, plan for about 147 N of real work at 0.5 MPa, which means this actuator lifts roughly 12.5 kg vertically with a 2:1 safety margin. Because it conforms to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises. Note this specific SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors without switching to an -S variant.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X225CA Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 245.3 N thrust to push heavy cartons onto a secondary belt at 225 mm of travel.
Vertical Parts Lift
Raises lightweight jigs or fixtures weighing up to 12.5 kg through a 225 mm vertical cycle, relying on the CA clevis to pivot smoothly.
Washdown Stopper Cylinder
Deploys a stainless-steel stop pin in a damp food-processing environment, where the corrosion-resistant barrel survives moisture exposure.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X225CA the Right Cylinder?
When sizing this 225 mm stroke actuator, the neighbouring Ø20 bore offers 157.0 N push at 0.5 MPa, while stepping up to the Ø32 provides 402.2 N, giving you clear boundaries if your load shifts. The CA rear pivot cover is ideal for clevis mounting, accommodating articulation through the stroke. With a 225 mm extension, be mindful of side-load and rod-bending forces; rigid guidance is recommended to prevent premature seal wear.
This model uses fixed TPU bumpers for end-of-stroke deceleration, not an adjustable air cushion (look to the MIC variant for that). Because a standard double-acting cylinder vents and drifts when air is lost or the valve centres, you must never rely on the bumper to hold a suspended load; integrate an external rod lock or pilot-operated check valve for fail-safe positioning.
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 MI25X225CA FAQ
At 0.5 MPa it provides 245.3 N push and 206.1 N pull. At 0.7 MPa it provides 343.4 N push and 288.5 N pull. The theoretical maximum force is 50 kgf at 1.0 MPa. The air port size is 1/8".
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG or EMSG switches. You would need the -S variant for position sensing. It uses fixed TPU bumper pads for deceleration and follows ISO 6432 mounting dimensions.
