About the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X100SU
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust actuation tasks. The riveted barrel and Ø10 mm piston rod shrug off mild corrosion, making it superior to painted alternatives in damp or washdown settings. Its built-in piston magnet supports CMSG, DMSG and EMSG switches for precise end-of-stroke detection, while the rear U cover provides a 90-degree port orientation for tight machinery layouts.
Because it conforms to ISO 6432 mounting dimensions, the body drops directly into standard mini-cylinder brackets and clevises. Plan for roughly 147 N of actual work at 0.5 MPa to maintain a safe margin, which translates to lifting about 12.5 kg vertically. Fixed TPU bumper pads absorb the impact at stroke extremes without adding bulk.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X100SU Is Used
Package Diverter Gate
Swings sorting flaps on logistics conveyors, using the 245.3 N thrust to push heavy cartons firmly into secondary chutes.
Pouch Sealing Press
Closes upper seal bars on vertical form-fill machines, relying on the 100 mm travel and rear U cover to fit compact frame gaps.
Textile Loom Tensioner
Adjusts yarn guide arms in humid manufacturing environments where the stainless rod prevents mild corrosion and ensures smooth movement.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI25X100SU the Right Cylinder?
When sizing this 25 mm bore, the smaller Ø20 generates 157.0 N of push at 0.5 MPa, whereas stepping up to the Ø32 yields 402.2 N. The 100 mm stroke is well within the 500 mm maximum, though maintaining accurate guiding is recommended to prevent rod bending over the travel distance. The 1/8" port matches the bore standard.
This SKU includes the -S magnet for CMSG, DMSG or EMSG sensors. Note that venting the chamber causes the piston to drift; the TPU pads only soften the end stops. Use an external pilot check valve to suspend a vertical load 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 MI25X100SU FAQ
At 0.5 MPa it provides 245.3 N push and 206.1 N pull. At 0.7 MPa it provides 343.4 N push and 288.5 N pull. The theoretical maximum force is 50 kgf at 1.0 MPa. The air port is 1/8" and the male rod thread is M10x1.25.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. To hold a vertical load securely, install an external rod lock or a pilot-operated check valve.
