About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X100SUTC
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavy-duty positioning where smaller bores stall. The stainless-steel barrel and Ø12 mm rod shrug off mild corrosion, making it highly suitable for damp washdown environments. Its riveted construction keeps the unit compact, while fixed TPU bumper pads absorb impact energy at the stroke ends.
Equipped with a 1/8 inch air port and a built-in magnet for CMSG, DMSG or EMSG switches, the 100 mm stroke provides ample travel for machine ejection tasks. Plan for a safe working load of roughly 241 N, which translates to lifting about 20.5 kg vertically with a 2:1 safety margin.

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 MI32X100SUTC Is Used
Package Diverting Gate
Actuates heavy routing flaps on logistics conveyors, utilizing the 402.2 N push force to deflect loaded cartons without stalling.
Stamping Ejector Pin
Ejects formed metal blanks from press dies, relying on the 100 mm stroke and fixed TPU bumpers to withstand repeated impact.
Pallet Stopper Arm
Deploys a robust stopping barrier at the end of roller conveyors, securely halting pallets up to the 20.5 kg vertical lift equivalent.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X100SUTC the Right Cylinder?
When sizing this 32 mm bore, dropping down to the Ø25 model reduces your 0.5 MPa push force to 245.3 N, whereas stepping up to the Ø40 bore yields 628.3 N for heavier mechanisms. Because this is a non-ISO-6432 round-body size, ensure your mounting hardware matches the included TC trunnion and U 90-degree back cover rather than standard mini brackets.
Remember that fixed TPU bumpers only decelerate the piston near the stroke end; they do not function as a brake. If your application must hold a vertical load when air pressure drops or the valve centers, you must add an external rod lock or a pilot-operated check valve to prevent 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 MI32X100SUTC FAQ
This 32 mm bore cylinder features a 1/8 inch air port and an M10x1.25 male 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 of 82 kgf at 1.0 MPa.
No, the fixed TPU bumper pads only decelerate the piston at the stroke end and do not act as a lock. The piston will drift if air is lost or the valve is centered; for vertical loads, install an external rod lock or pilot check valve. The built-in magnet supports CMSG, DMSG and EMSG sensors.
