About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X90CA
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 riveted barrel and rod resist mild corrosion, making it superior to painted alternatives in damp environments. It features a 1/8" port and an M10x1.25 male rod thread.
Because the 245.3 N rating is a theoretical maximum, plan for a safe working load of roughly 147 N to account for friction and pressure drops. In vertical lifting scenarios, this translates to hoisting about 12.5 kg with a 2:1 safety margin. The rear CA clevis facilitates pivoting mountings, while fixed TPU bumper pads absorb end-of-stroke impacts.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X90CA Is Used
Package Diverter Arm
Drives a 90 mm swing arm to push parcels weighing up to 12 kg off a main conveyor belt using the CA rear clevis for smooth articulation.
Press Pin Insertion
Exerts 245.3 N of push force at 0.5 MPa to seat dowel pins into aluminium jigs, relying on the stainless rod to resist workshop coolant splashes.
Carton Flap Folder
Actuates a folding mechanism on a packaging line, utilizing the fixed TPU bumper pads to soften the impact at the end of the 90 mm extension cycle.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X90CA the Right Cylinder?
When sizing this 25 mm bore, compare it against its neighbours: a 20 mm bore yields 157.0 N of push at 0.5 MPa, whereas stepping up to a 32 mm bore provides 402.2 N. Choose this model when your application requires approximately 245 N of thrust over a 90 mm stroke. Note that a plain cylinder drifts if air pressure is lost or the valve is centred; the bumpers only decelerate the stroke end and do not act as a brake. For secure load holding, integrate an external rod lock or pilot check valve.
This specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG position switches. If your machinery requires electronic end-of-stroke detection, select the -S variant instead. The included CA back cover is ideal for pivoting articulations, and you can pair the front face with LB foot, FA flange, SDB pivot, or TC trunnion brackets.
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 MI25X90CA FAQ
This 25 mm bore cylinder uses a 1/8" air port. At 0.5 MPa it generates 245.3 N of push and 206.1 N of pull. At 0.7 MPa, push increases to 343.4 N and pull to 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You must choose the -S variant if you require electronic position sensing. The unit uses the ISO 6432 mounting interface and features a CA pivot clevis.
