About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X180SCM
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust linear motion tasks. The Ø25 mm bore operates on a 1/8" port, and the 180 mm stroke falls well within the 500 mm standard limit. Its riveted stainless barrel and piston rod resist mild corrosion, giving it a real edge over painted alternatives in damp processing areas. The built-in magnet (-S) directly supports CMSG, DMSG, and EMSG position switches.
For practical sizing, plan for roughly 147 N of actual work at 0.5 MPa to maintain a safe margin. This translates to lifting about 12.5 kg vertically, letting you match the cylinder to real part weights. The CM round end cover provides a clean rear finish, while fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X180SCM Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 180 mm stroke to shift parcels cleanly between parallel conveyor belts.
Textile Loom Tensioner
Maintains precise fabric tension by pushing a guide roller, leveraging the 245.3 N force to keep woven material tracking straight.
Carton Flap Folder
Folds corrugated box flaps prior to tape sealing, with the stainless build surviving dusty warehouse environments.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X180SCM the Right Cylinder?
When sizing this 180 mm stroke model, verify your load against the 245.3 N push and 206.1 N pull ratings at 0.5 MPa. If you need less force, stepping down to the Ø20 bore provides 157.0 N of push, while upgrading to the Ø32 yields 402.2 N for heavier resistance. Because the 180 mm stroke extends the Ø10 mm rod significantly, check your side-load geometry to prevent rod bending and premature seal wear.
The Ø25 bore uses the ISO 6432 mini-cylinder mounting interface, so it drops directly into standard brackets and clevises. Remember that the fixed TPU bumpers only decelerate the end of stroke; they do not act as a brake. If air pressure drops, the piston will drift, so fit an external rod lock or pilot check valve for suspended loads. This SKU includes the -S magnet for sensors and the CM round back cover.
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 MI25X180SCM FAQ
This Ø25 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 -S suffix indicates a built-in piston magnet compatible with CMSG, DMSG, and EMSG switches. The CM designation specifies a round rear end cover. Additionally, the Ø25 bore adheres to ISO 6432 mounting dimensions, allowing it to fit standard mini-cylinder brackets.
