About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X135SU
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MI32X135SU is a robust round-body mini cylinder built for demanding automation. This double-acting actuator features a stainless-steel barrel and piston rod, offering reliable mild corrosion resistance for damp or washdown environments. The riveted construction maintains a compact profile while housing a 1/8" air port and a 135 mm stroke.
Fixed TPU bumper pads absorb impact energy at the stroke extremes, smoothly decelerating the piston without the complexity of adjustable cushioning. Planning for about 241 N of actual work at 0.5 MPa leaves a safe operational margin, which translates to lifting roughly 20.5 kg vertically. Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG or EMSG position switches.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G. Note: the Ø32 bore is a larger, non-ISO-6432 size.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X135SU Is Used
Package Diverting
Actuates routing gates on packaging lines, using its 402.2 N thrust to push heavy cartons securely onto secondary conveyor tracks.
Textile Loom Tensioning
Regulates fabric tension in wet processing zones where the stainless steel rod resists humidity and mild chemical splash.
Pallet Stopper Arm
Deploys a 135 mm stroke to halt incoming pallets at loading stations, relying on fixed TPU pads to soften the end-of-stroke impact.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X135SU the Right Cylinder?
When sizing this 32 mm bore, the smaller Ø25 generates 245.3 N of push at 0.5 MPa, while the larger Ø40 provides 628.3 N, giving you clear boundaries for scaling your force requirements. The U rear cover provides a 90-degree port orientation to simplify plumbing in tight spaces. If your process requires the rod to stay put during a pressure drop or valve shift, be aware this standard cylinder will drift; you should integrate an external rod lock or pilot-operated check valve. The 135 mm stroke is well within the 500 mm maximum, though ensuring proper guide alignment prevents rod bending under lateral loads.
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 MI32X135SU FAQ
This double-acting cylinder uses a 1/8" port and generates 402.2 N push and 345.6 N pull at 0.5 MPa. At 0.7 MPa it provides 563 N push and 483.8 N pull, with a theoretical maximum force of 82 kgf at 1.0 MPa.
Yes, the -S suffix means a piston magnet is built-in, allowing you to mount CMSG, DMSG or EMSG switches. It does not hold position unpowered; the TPU bumpers only decelerate the stroke end, so use a pilot check valve for load holding.
