About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X85CM
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavier automation tasks with confidence. The stainless-steel barrel and Ø12 mm rod shrug off mild corrosion, making it far superior to painted alternatives in damp or washdown environments. It features a CM round end cover and a 1/8" port.
The riveted construction keeps the body compact, while fixed TPU bumper pads absorb impact at the stroke ends to protect your mechanism. 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. Note that this specific SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors.

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 MI32X85CM Is Used
Package Diverting
Pushes medium-weight cartons off a main conveyor belt using its 402.2 N push force and 85 mm stroke.
Clamp Actuation
Secures aluminium extrusions in a machining fixture, providing reliable holding via the CM round end cover.
Flap Folding
Folds heavy cardboard flaps on a case erector where the stainless build resists humid packing environments.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X85CM the Right Cylinder?
When sizing this 32 mm bore, compare it against its neighbours: a 25 mm bore gives 245.3 N of push at 0.5 MPa, whereas stepping up to the 40 mm bore yields 628.3 N. This model hits a strong middle ground for medium-force tasks. If your process drops air pressure or centres the valve, the piston will drift; the bumpers only decelerate the end of travel rather than locking the rod, so fit an external pilot check valve if you need to suspend a load.
The 85 mm stroke is well within the 500 mm maximum, keeping rod bending stress low. You can mount this unit using LB foot brackets, FA flanges, SDB pivot blocks or TC trunnions. Because this SKU has no internal magnet, position sensing is impossible without switching to the -S variant.
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 MI32X85CM FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N. At 0.7 MPa it pushes 563 N and pulls 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa. The air port is 1/8".
No, this specific SKU does not include a magnet, so CMSG, DMSG or EMSG switches will not function. You must select the -S variant to enable magnetic sensing.
