About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X225CM
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles substantial work within a compact footprint. The 25 mm bore operates on a 1/8" port, yielding 206.1 N of pull force on the return stroke. Its stainless barrel and rod naturally resist mild corrosion, giving it a real edge over painted-steel alternatives in damp or washdown environments.
The 225 mm stroke travels smoothly at 30-800 mm/s, with fixed TPU bumper pads decelerating the impact at each end. For practical sizing, plan for roughly 147 N of real work at 0.5 MPa, which means it can safely lift about 12.5 kg vertically with a 2:1 safety margin. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X225CM Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using its 225 mm stroke to shift parcels cleanly between parallel conveyor belts.
Textile Loom Tensioner
Maintains precise tension on yarn feeds in a humid textile mill, leveraging the stainless build to resist wet environmental conditions.
Bin Lid Automation
Pivots heavy loading bin lids open and closed, relying on the 245.3 N push force to overcome the lid weight and friction.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X225CM the Right Cylinder?
When sizing this 25 mm bore, stepping down to a 20 mm cylinder drops the 0.5 MPa push force to 157.0 N, while jumping up to a 32 mm bore raises it significantly to 402.2 N. The CM round end back cover on this unit provides a clean rear profile for standard mounting orientations. For broader installation flexibility, the ISO 6432 mounting interface allows seamless integration into standard mini-cylinder brackets and clevises.
At a 225 mm stroke, the Ø10 mm piston rod extends far enough that side-loading and rod bending become critical factors; ensure the load is guided to prevent premature seal wear. Furthermore, the fixed TPU bumpers only soften the stroke-end impact and do not act as a brake. If the application requires the load to be held in place during air loss or valve centering, you must add an external rod lock or a pilot-operated check valve, as the piston will drift.
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 MI25X225CM FAQ
This 25 mm bore cylinder features a 1/8" port and an M10x1.25 male rod thread. It generates 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.
Yes, the Ø25 bore uses the ISO 6432 mounting interface, so it drops directly into standard mini-cylinder brackets, foot mounts (LB), and trunnions (TC). However, because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG magnetic switches without replacing the cylinder.
