About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X260SU
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 260 mm stroke with ease. The Ø25 bore uses a 1/8" port and a Ø10 rod with an M10x1.25 male thread. Its stainless barrel and piston rod naturally resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. The riveted body keeps the unit compact, while fixed TPU bumper pads absorb the impact at stroke extremes.
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. Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG or EMSG position switches. The U back cover provides a 90-degree port orientation for tight routing. It conforms to the ISO 6432 mounting interface, dropping directly into standard mini-cylinder brackets and clevises.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X260SU Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 245.3 N push force to redirect heavy cartons onto secondary belts.
Vertical Parts Lift
Raises lightweight jigs over a 260 mm gap; the 12.5 kg safe vertical lift capacity easily handles small metal blanks.
Damp Environment Ejector
Stainless construction survives humid food-processing zones while pushing washed containers out of a mold station.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X260SU the Right Cylinder?
When sizing this 245.3 N (at 0.5 MPa) unit, compare it against the smaller Ø20 bore that yields 157.0 N, or step up to the larger Ø32 bore providing 402.2 N if your payload demands more push. The 260 mm stroke is well within the 500 mm maximum for this bore, but at extended lengths you should carefully manage side loading to avoid rod bending. The U rear cover dictates a 90-degree port direction, so verify your tubing clearance.
Remember that fixed TPU bumpers only decelerate the end of travel; they do not function as a brake. If air pressure drops or the valve is centred, the piston will drift and drop the load. To suspend a vertical weight securely, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 MI25X260SU FAQ
At 0.5 MPa it provides 245.3 N push and 206.1 N pull. At 0.7 MPa it yields 343.4 N push and 288.5 N pull. The theoretical maximum force is 50 kgf at 1.0 MPa. This Ø25 bore uses a 1/8" air port.
Yes, the -S suffix means a piston magnet is built in, allowing CMSG, DMSG or EMSG switches to be fitted. The U back cover provides a 90-degree port orientation for compact tubing. It uses the ISO 6432 mounting interface for standard brackets.
