About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X450CM
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles demanding 450 mm strokes with ease. The Ø25 bore uses a 1/8" air 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 environments. The CM round end back cover keeps the rear profile smooth for compact machine integration.
Because the 245.3 N rating leaves little room for friction, plan for about 147 N of actual work at 0.5 MPa. For vertical lifting, that equals roughly 12.5 kg when you keep a 2:1 safety margin. Fixed TPU bumper pads absorb the impact at the stroke extremes, decelerating the piston without the complexity of adjustable cushioning. This SKU lacks the -S magnet, so it cannot host CMSG, DMSG or EMSG sensors without changing to a magnetised variant.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X450CM Is Used
Diverting Gate Actuation
Pushes sorting flaps on packaging lines using its 245.3 N thrust, with the stainless build surviving humid washdown cleaning cycles.
Light Press Assembly
Provides a consistent 450 mm downward stroke to seat foam gaskets into housings, relying on fixed TPU pads to soften the end stop.
Carton Pusher
Ejects filled cartons from a loading bay, where the CM round end and compact riveted body fit neatly into tight conveyor framework.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X450CM the Right Cylinder?
Sizing around this model means looking at the neighbouring bores. Dropping to a Ø20 reduces the 0.5 MPa push force to 157.0 N, while stepping up to a Ø32 raises it to 402.2 N. If your application loses air or centres the valve, this plain cylinder will drift and cannot hold position; the TPU pads only soften the end of stroke. To lock a suspended load, add an external rod lock or a pilot-operated check valve.
The 450 mm stroke is well within the 500 mm standard limit for this bore, though at full extension the Ø10 rod is more susceptible to side-loading and bending forces. Mounting options include LB foot brackets, FA flanges, SDB pivot blocks and TC trunnions, while the ISO 6432 mounting interface ensures it drops straight into standard mini-cylinder clevises.
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 MI25X450CM FAQ
This Ø25 bore cylinder has 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, 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.
No, this specific SKU does not include a magnet. To use CMSG, DMSG or EMSG reed switches, you must select the -S variant of the MI series. Additionally, it uses fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable air cushion.
