About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X105CM
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MI32X105CM is a double-acting round-body mini cylinder built for rigorous actuation. The stainless-steel barrel and Ø12 mm piston rod naturally resist mild corrosion, giving it a distinct edge over painted alternatives in damp or washdown environments. Air routes through a 1/8" port, and the CM round end cover provides a clean, compact rear profile for straightforward mounting.
Fixed TPU bumper pads absorb impact energy at the stroke extremes, decelerating the piston without the complexity of adjustable cushions. Because this SKU lacks the -S magnet, it cannot host CMSG, DMSG, or EMSG reed switches. 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.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X105CM Is Used
Package Diverting Gate
Actuates a heavy routing flap on a logistics conveyor, using its 402.2 N push force to deflect parcels reliably at high throughput.
Stamping Pin Press
Drives a 105 mm stroke marking pin into aluminum housings on an assembly line, benefiting from the stainless build in coolant-misted areas.
Pallet Stopper Arm
Extends a mechanical stop to halt pallets at a workstation, relying on the CM round end cover for stable rear pivot mounting.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X105CM the Right Cylinder?
When sizing this 32 mm bore, stepping down to a 25 mm unit drops the 0.5 MPa push force to 245.3 N, whereas moving up to a 40 mm bore yields 628.3 N. The 105 mm stroke is well within the 500 mm standard limit, keeping the assembly compact while providing ample travel. Remember that the fixed TPU bumpers only soften the end-of-stroke impact; they do not function as a brake. If your application must hold a vertical load during a loss of air pressure or valve centering, you must integrate an external rod lock or a pilot-operated check valve, as the piston will drift otherwise.
This base configuration uses a male M10x1.25 rod thread and operates effectively across the 30-800 mm/s speed range. To add position sensing capabilities, you would need to specify the -S magnet variant, as this standard model cannot accept sensors.
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 MI32X105CM FAQ
This 32 mm bore cylinder features a 1/8" air port and a Ø12 mm rod. 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, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You must select the -S variant (with magnet) for position sensing. Additionally, as a non-ISO-6432 Ø32 round-body cylinder, it relies on its own compact riveted dimensions rather than standard mini-cylinder interface footprints.
