About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X150CM
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MI32X150CM is a double-acting round-body mini cylinder built with a stainless-steel barrel and piston rod. The riveted construction shrinks the footprint while resisting mild corrosion, making it highly suitable for damp production areas where painted steel quickly degrades. It features a 150 mm stroke, a 1/8" port, and a CM round end cover for straightforward rear mounting.
Because this bore sits outside the ISO 6432 standard, it is classified strictly as a round-body mini cylinder rather than a drop-in ISO unit. Plan for a safe working load of roughly 241 N, which is about 60 percent of the 0.5 MPa push rating. Alternatively, it can lift a 20.5 kg payload vertically when applying a 2:1 safety margin. Fixed TPU bumper pads absorb the impact at stroke end, though this SKU lacks a magnet and therefore 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 MI32X150CM Is Used
Package Diverter Gate
Actuates a heavy routing flap on a logistics conveyor belt, using its 402.2 N thrust to push dense parcels onto secondary sorting chutes.
Textile Loom Tensioner
Maintains consistent mechanical tension on industrial weaving equipment, leveraging the 150 mm stroke to compensate for material feed variations in damp environments.
Pallet Stacking Pusher
Advances cardboard cartons along a roller accumulation line prior to stretch wrapping, safely moving loads under the 241 N working threshold.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X150CM the Right Cylinder?
When sizing this actuator, compare it against its neighbours: a Ø25 bore provides 245.3 N of push at 0.5 MPa, while stepping up to a Ø40 yields 628.3 N. Choose the Ø32 when your application demands 402.2 N of thrust. The 150 mm stroke is well within the 500 mm maximum, but long strokes naturally invite rod bending, so ensure the load is guided to prevent side-load damage. The CM round end cover dictates a specific rear port and mounting orientation.
Remember that a standard double-acting cylinder drifts when air pressure drops or the directional valve centres, as the fixed TPU pads only decelerate the end of travel and act as neither a brake nor a lock. To suspend a load safely during an air loss event, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit. Finally, because this specific SKU is supplied without a magnet, position sensing is impossible; you must specify an -S variant to utilise magnetic switches.
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 MI32X150CM FAQ
This double-acting cylinder uses a 1/8" port and generates a push force of 402.2 N and a pull force of 345.6 N at 0.5 MPa. At 0.7 MPa, the push increases to 563 N and the pull to 483.8 N. The theoretical maximum force is 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 must order the -S variant to enable magnetic sensing. The unit relies on fixed TPU bumper pads for end-of-stroke deceleration and features a stainless-steel riveted round body.
