Airtac MI25~40 Stainless Steel Mini Cylinder MI25X600U
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X600U is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 600mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X600U
Generating 245.3 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles substantial work within a compact footprint. The 25 mm bore pairs a 10 mm stainless-steel piston rod with a 1/8" port, while the 600 mm stroke is a non-standard, made-to-order length that exceeds the usual 500 mm maximum for this bore size. The riveted stainless construction resists mild corrosion, making it superior to painted alternatives in damp environments.
Because it lacks the -S suffix, this specific SKU cannot accept CMSG, DMSG, or EMSG magnetic switches. Fixed TPU bumper pads absorb end-of-stroke impacts, though they decelerate rather than cushion adjustably. In practical terms, you can expect a safe working load of roughly 147 N, allowing it to lift about 12.5 kg vertically with a 2:1 safety margin.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X600U Is Used
Carton Push-off Diverter
Uses the 245.3 N thrust at 0.5 MPa to push heavy cardboard cartons from a main packaging line onto a secondary spur belt.
Pallet Guide Alignment
Deploys the 600 mm stroke to extend and square up pallets entering a stretch wrapper, retracting to clear the wrapping path.
Parts Ejection Station
Leverages the 12.5 kg vertical lift capacity to eject finished molded parts from a press bed into a collection bin.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X600U the Right Cylinder?
When sizing this actuator, consider the step down to the Ø20 bore, which provides 157.0 N of push at 0.5 MPa, or the step up to the Ø32 bore, delivering 402.2 N. The extended 600 mm stroke demands careful attention to side loading; ensure the load is guided to prevent rod bending over that distance. The U-style back cover provides a 90-degree port orientation and pivot mounting capability, conforming to ISO 6432 mounting dimensions for standard mini-cylinder brackets.
Note that a standard double-acting cylinder drifts when air is removed or the valve is centered, as the TPU bumpers only soften the stroke end and do not act as a brake. To suspend a load safely, 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 MI25X600U FAQ
At 0.5 MPa, the push force is 245.3 N and the pull force is 206.1 N. At 0.7 MPa, push is 343.4 N and pull is 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa. It features a 1/8" port, an M10x1.25 male rod thread, and operates at speeds between 30-800 mm/s.
No, because this model lacks the -S suffix, it does not have an internal piston magnet and cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for position sensing. The unit uses fixed TPU bumper pads for deceleration and conforms to ISO 6432 mounting dimensions.
