About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X500SCM
Generating 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavy-duty positioning tasks. The stainless-steel barrel and rod shrug off mild corrosion, making it superior to painted alternatives in damp or washdown environments. A 500 mm stroke provides extended travel, while the 1/8" port and M10x1.25 male rod thread ensure robust pneumatic connections.
Equipped with a built-in magnet (-S), it supports CMSG, DMSG, and EMSG switches for precise end-of-stroke detection. The CM round end back cover offers a clean rear profile. Plan for roughly 241 N of actual work at 0.5 MPa to maintain optimal performance. This translates to lifting about 20.5 kg vertically with a safe 2:1 margin, letting you match real part weights accurately.

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 MI32X500SCM Is Used
Pallet Diverters
Pushes heavy loaded pallets across transfer lines using its 402.2 N push force, while the stainless construction survives dusty warehouse environments.
Case Erectors
Extends the full 500 mm stroke to fold and seal large corrugated cardboard cartons, relying on the built-in magnet for timing confirmation.
Textile Looms
Actuates heavy guide frames in humid dyeing facilities, where the stainless steel rod resists mild corrosion and the CM round end eases rear mounting.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X500SCM the Right Cylinder?
Sizing this 32 mm bore against its neighbours shows a clear step up from the 25 mm class (245.3 N push @0.5 MPa) and a slight step down from the 40 mm class (628.3 N push @0.5 MPa). The 500 mm stroke is the maximum standard length for this bore; at full extension, minimize side-loading to prevent rod bending and premature seal wear. The fixed TPU bumper pads decelerate the piston near the stroke end but do not act as a lock. If your application must hold a vertical load when air is lost or the valve is centred, the piston will drift. You must integrate an external rod lock or a pilot-operated check valve for secure positioning.
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 MI32X500SCM FAQ
The 1/8" port supplies air to deliver 402.2 N push and 345.6 N pull at 0.5 MPa. At 0.7 MPa, it provides 563 N push and 483.8 N pull. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, this model uses fixed TPU bumper pads that merely decelerate the stroke end. For adjustable air cushioning, you need the MIC variant. This unit includes a magnet for CMSG/DMSG/EMSG sensors and features a CM round end cover.
