About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X140CM
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles demanding actuation with a 140 mm stroke. The stainless-steel barrel and piston rod provide reliable mild corrosion resistance, outperforming painted alternatives in damp or washdown settings. Its riveted construction remains compact while the CM round end cover cleanly caps the rear body.
Equipped with fixed TPU bumper pads to absorb end-of-stroke impact, the unit operates at 30-800 mm/s via a 1/8 inch port. 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. Note 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 MI32X140CM Is Used
Package Diverting
Actuates routing gates on packaging lines, using its 402.2 N push force to deflect heavy cartons reliably at speed.
Clamp Actuation
Secures aluminium extrusions during machining operations, where the stainless build resists cutting fluid splatter.
Pallet Stops
Raises and lowers end-stops on roller conveyors, handling loads up to the 20.5 kg vertical lift threshold.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X140CM the Right Cylinder?
When sizing this 32 mm bore, stepping down to a 25 mm bore drops the 0.5 MPa push force to 245.3 N, while moving up to a 40 mm bore increases it to 628.3 N. The 140 mm stroke is well within the 500 mm maximum standard stroke, keeping the assembly standard and avoiding made-to-order delays. For side-load durability on this length, ensure rigid guidance to prevent rod bending.
Because this is a base MI variant without an -S suffix, it cannot accept magnetic switches. The CM round end cover dictates the rear mounting orientation, and you can utilise LB foot, FA flange, SDB pivot or TC trunnion brackets. Remember that the TPU bumpers only decelerate the stroke end; the piston will drift if air is lost. To hold a load securely during a pressure drop, install an external rod lock or a pilot-operated check valve.
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 MI32X140CM FAQ
This 32 mm bore cylinder uses a 1/8 inch port and a 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, this specific SKU does not include a magnet, so CMSG, DMSG or EMSG switches cannot be used. You would need the -S variant for sensing. The unit relies on fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable air cushion.
