Airtac MI25~40 Stainless Steel Mini Cylinder MI25X225SU
The AirTAC Airtac MI25~40 Stainless Steel Mini Cylinder MI25X225SU 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 MI25X225SU
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles substantial work within a compact footprint. The rolled and riveted round body pairs a corrosion-resistant barrel and rod with fixed TPU bumper pads that absorb end-of-stroke impacts without needing manual adjustment. Because it includes a piston magnet, the unit is fully primed for CMSG, DMSG or EMSG position sensing.
Engineered to the ISO 6432 mounting interface, the Ø25 body drops directly into standard mini-cylinder brackets and clevises. The 1/8" port feeds the 10 mm rod, and the U-type back cover provides a 90-degree port orientation for tight machinery layouts. In practical terms, you can expect about 147 N of usable work at 0.5 MPa, which translates to lifting a 12.5 kg part vertically with a safe 2:1 margin.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X225SU Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 225 mm stroke to shift parcels cleanly between adjacent belts.
Parts Press Insertion
Pushes a 12 kg bearing housing into a housing bore, operating comfortably within the 147 N safe working load at 0.5 MPa.
Vertical Material Lift
Raises lightweight tote bins between conveyor tiers in a humid washdown area, relying on the stainless rod to resist mild corrosion.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X225SU the Right Cylinder?
Sizing this 225 mm stroke model requires looking both down and up the range. If the 245.3 N push at 0.5 MPa is excessive, the Ø20 bore offers 157.0 N; if you need more muscle, the Ø32 jumps to 402.2 N. The 225 mm travel is well within the 500 mm standard limit, though at this extension the 10 mm rod is more susceptible to side-loading, so a guided carriage or load coupling is advised to prevent bending.
The U-type rear cover gives a 90-degree mounting pivot, complementing LB foot, FA flange and TC trunnion options. Remember that the fixed TPU bumpers only decelerate the stroke end; they do not function as a brake. If the load must remain suspended when air is cut or the valve is centred, the piston will drift, dictating an external pilot check valve or rod lock.
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 MI25X225SU FAQ
This Ø25 double-acting cylinder uses a 1/8" port and a 10 mm rod. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, with a theoretical maximum of 50 kgf at 1.0 MPa.
No, the fixed TPU bumper pads only decelerate the stroke end and do not act as a lock; the piston will drift if air is lost, requiring an external rod lock for holding. The built-in magnet (-S) supports CMSG, DMSG and EMSG switches for position detection.
