Airtac MI25~40 Stainless Steel Mini Cylinder MI25X430SCA
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X430SCA is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 430mm 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 MI25X430SCA
Delivering 245.3 N of push force at 0.5 MPa, this AirTAC MI25X430SCA is a double-acting round-body mini cylinder built from a stainless-steel barrel and rod. The riveted construction shrinks the envelope while holding up against mild corrosion and washdowns better than painted alternatives. Because the Ø25 bore falls inside the ISO 6432 range, it drops directly into standard mini-cylinder brackets and clevises without custom machining.
The 430 mm stroke sits safely inside the 500 mm standard limit for this bore, and the CA rear cover provides a pivot clevis for articulated mounting. Fixed TPU bumper pads absorb the impact at stroke extremes to protect the mechanism. Plan for roughly 147 N of actual work at 0.5 MPa, which means you can vertically lift about 12.5 kg with a safe 2:1 margin.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X430SCA Is Used
Diverting Gate Actuation
Swings a sorting diverter on a packaging conveyor using the CA pivot clevis to handle the 430 mm reach and 12.5 kg gate mass.
Carton Push-off Assembly
Pushes filled cartons from an accumulation roller table, utilizing the 245.3 N thrust to overcome box friction.
Textile Beam Indexing
Shifts heavy textile beams laterally across a processing line, relying on the stainless rod to withstand humid conditions.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X430SCA the Right Cylinder?
If 245.3 N of push at 0.5 MPa is too much, step down to the Ø20 bore (157 N push); if you need more muscle, the Ø32 bore jumps to 402 N. The built-in -S magnet enables CMSG, DMSG, or EMSG position sensing, and the CA pivot cover pairs with LB foot, FA flange, SDB pivot, or TC trunnion hardware. Air enters via the 1/8" port.
Pushing a load out to 430 mm raises side-load risks, so keep the rod guided to prevent bending. Remember that venting the air causes the piston to drift—the TPU pads only soften the end of travel and do not act as a brake. To lock a load mid-stroke, install an external rod lock or pilot check valve.
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 MI25X430SCA FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N. At 0.7 MPa it pushes 343.4 N and pulls 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa. The air port is 1/8".
Yes, the -S suffix means a piston magnet is included for CMSG, DMSG, or EMSG switches. The cylinder does not hold position if air is lost; the fixed TPU bumpers only decelerate the stroke end, so use an external rod lock for holding.
