About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X50SUTC
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MI32X50SUTC is a double-acting round-body mini cylinder built for demanding compact actuation. Its stainless-steel barrel and Ø12 mm rod shrug off mild corrosion, making it highly suitable for damp washdown environments where painted steel quickly degrades. The riveted construction keeps the unit compact while fixed TPU bumper pads absorb impact energy at the stroke ends. Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG or EMSG position switches.
This 32 mm bore operates on a 1/4 inch port and offers a substantial 82 kgf theoretical maximum at 1.0 MPa. For practical sizing, plan for a safe working load of roughly 241 N, which equates to lifting about 20.5 kg vertically with a 2:1 safety margin. The rear U cover provides a 90-degree port orientation, and the included TC trunnion accessory simplifies pivot mounting on moving machinery.

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 MI32X50SUTC Is Used
Package Diverting Gate
Actuates a heavy routing flap on a logistics conveyor, using the 402.2 N push force to reliably shift boxed goods into secondary sorting lanes without stalling.
Pouch Sealing Press
Drives the upper sealing jaw on a vertical form-fill-seal machine, where the stainless build resists daily washdown and the 20.5 kg vertical lift capacity easily crushes product bags.
Stamping Pin Actuation
Pushes a date-coding pin into aluminum extrusions on an output table, relying on the TC trunnion to accommodate the slight angular misalignment during the rapid 50 mm stroke.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X50SUTC the Right Cylinder?
When sizing this 32 mm bore, compare it directly with its neighbours: a 25 mm bore gives 245.3 N of push at 0.5 MPa, while stepping up to a 40 mm bore yields 628.3 N. The MI32X50SUTC sits perfectly in the middle for medium-force tasks. Note that a standard double-acting cylinder like this will drift if air pressure drops or the valve is centred; the TPU bumpers only decelerate the stroke end and do not act as a brake. If your application requires the load to be held securely in place during a power loss, you must add an external rod lock or a pilot-operated check valve.
The 50 mm stroke is well within the 500 mm maximum standard stroke for this bore, meaning no made-to-order wait times. With the -S magnet fitted, you can easily attach reed or electronic sensors for end-of-stroke confirmation. The TC trunnion mount pairs with the U back cover to give you flexible pivoting installation options on assembly lines.
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 MI32X50SUTC FAQ
This 32 mm bore cylinder features a 1/4 inch air port and a male M10x1.25 rod thread. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum force of 82 kgf at 1.0 MPa.
No, the base MI uses fixed TPU bumper pads to decelerate the stroke end, not an adjustable air cushion; for adjustable cushioning you would need the MIC variant. However, because this SKU has the -S magnet, it fully supports CMSG, DMSG and EMSG electronic or reed switches.
