Airtac MI25~40 Stainless Steel Mini Cylinder MI25X225SCA
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X225SCA is a genuine double acting round-body mini air cylinder with a Ø25mm bore and 225mm 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 MI25X225SCA
Delivering 245.3 N of push force at 0.5 MPa, the AirTAC MI25X225SCA is a double-acting round-body mini cylinder built for rigorous actuation. Its stainless-steel barrel and Ø10 mm rod shrug off mild corrosion, giving it a real edge over painted-steel alternatives in damp or washdown-prone environments. The CA rear pivot cover provides a robust clevis mount, while the 1/8" port feeds the 30-800 mm/s speed range.
At 0.5 MPa, plan for roughly 147 N of actual work output, which translates to lifting about 12.5 kg vertically with a sensible 2:1 safety margin. Because this Ø25 bore matches ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises without redesign. The integrated -S piston magnet allows precise position tracking using CMSG, DMSG or EMSG switches, and fixed TPU bumper pads absorb the impact at stroke extremes.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X225SCA Is Used
Textile Loom Beam Indexing
Uses the CA pivot clevis to swing and advance heavy fabric beams through a 225 mm stroke, relying on the 245.3 N push force to shift the load smoothly.
Bottling Line Diverter Gate
Stainless construction withstands washdown spray while the built-in -S magnet triggers DMSG sensors to confirm gate position for high-speed routing.
Packaging Flap Folder
Extends 225 mm to fold large corrugated carton flaps, with the TPU bumpers decelerating the impact to protect delicate packaging materials.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X225SCA the Right Cylinder?
When sizing this 225 mm stroke unit, consider the neighbouring bores: the Ø20 delivers 157.0 N push at 0.5 MPa if your load is lighter, while the Ø32 jumps to 402.2 N for heavier demands. A 225 mm extension creates a long lever arm, so carefully manage side loading to prevent rod bending and premature seal wear. If your application must hold a vertical load mid-stroke, remember that venting the air or centring the valve causes the piston to drift downward; the TPU pads only soften the end stops. You will need an external pilot-operated check valve or a dedicated rod lock to secure the payload safely.
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 MI25X225SCA FAQ
This Ø25 mm bore cylinder features a 1/8" air port and an M10x1.25 male rod thread. The double-acting thrust outputs are 245.3 N push and 206.1 N pull at 0.5 MPa, increasing to 343.4 N push and 288.5 N pull at 0.7 MPa. The theoretical maximum force is 50 kgf at 1.0 MPa.
No, the piston will drift if air pressure is lost or the directional valve is centred. The fixed TPU bumper pads only decelerate the stroke end; they do not function as a braking lock. For vertical load holding, you must install an external pilot check valve or a mechanical rod lock.
