About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X230SCA
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles demanding 230 mm stroke tasks. The Ø25 bore operates on a 1/8" port and conforms to ISO 6432 mounting dimensions, dropping seamlessly into standard mini-cylinder brackets and clevises. Its riveted stainless barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. The included -S piston magnet enables direct mounting of CMSG, DMSG or EMSG switches for position sensing.
Built with fixed TPU bumper pads to absorb end-of-stroke impact, the unit safely lifts about 12.5 kg vertically when applying a 2:1 safety margin to the 0.5 MPa output. Plan for roughly 147 N of actual work under standard pressure rather than pushing the absolute theoretical limit. The CA rear cover provides a pivot clevis for articulated rod-end loading.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X230SCA Is Used
Package Diverter Arm
Drives a 230 mm swing gate on a packaging line, using the CA clevis to pivot and push parcels weighing up to 12 kg onto an auxiliary belt.
Vertical Parts Lift
Elevates lightweight plastic totes in a cleanroom environment, exploiting the stainless build for humidity resistance and the magnet for top-position confirmation.
Welding Fixture Clamp
Extends to hold a steel bracket in a spot-welding jig, applying 147 N of secure clamping force at 0.5 MPa without marking the part.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X230SCA the Right Cylinder?
When sizing this 230 mm stroke unit, the Ø20 bore below supplies 157.0 N push at 0.5 MPa, while the larger Ø32 offers 402.2 N if your payload exceeds the 147 N practical working threshold. Because this SKU features the -S magnet, it is fully ready for CMSG, DMSG or EMSG electronic and reed sensors. The CA pivot back cover accommodates angular misalignment during extension.
A 230 mm stroke on a Ø10 mm rod demands careful side-load management to prevent premature seal wear and rod bending; ensure your guiding geometry is rigid. Remember that venting the air or centering the valve causes the piston to drift, as the TPU bumpers only decelerate the stroke end rather than locking the load. Specify an external pilot check valve or rod lock if you need strict position holding.
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 MI25X230SCA FAQ
This Ø25 mm bore cylinder features a 1/8" port and an M10x1.25 male rod thread. At 0.5 MPa it pushes with 245.3 N and pulls with 206.1 N. At 0.7 MPa the push is 343.4 N and pull is 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only decelerate the rod near the stroke end; they do not act as a brake. For vertical loads, you must install an external rod lock or a pilot-operated check valve to prevent dropping.
