About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X175SCM
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavier automation tasks with ease. The stainless-steel barrel and Ø12 mm piston rod shrug off mild corrosion, making it highly suitable for damp washdown environments where painted steel alternatives degrade. Riveted construction keeps the unit compact, while the built-in piston magnet allows direct mounting of CMSG, DMSG or EMSG sensors for position detection. Fixed TPU bumper pads absorb the impact at stroke extremes to protect the mechanism.
With a 1/8" air port driving the 32 mm bore, you can plan for a safe working load of roughly 241 N, or about 60 percent of the 0.5 MPa rating. In vertical lifting scenarios, this translates to hoisting approximately 20.5 kg safely when applying a 2:1 margin. The CM round end back cover provides a clean rear profile for straightforward integration into your assembly.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X175SCM Is Used
Package Diverting
Actuates a heavy-duty routing gate on a parcel sorting line, using the 402.2 N push force to reliably pivot fully loaded pallets onto secondary chutes.
Material Pressing
Provides consistent downward clamping pressure on an aluminium extrusion fixture, safely applying around 241 N of working load without deforming the workpiece.
Vertical Tray Lifting
Raises component trays in a humid storage retrieval system, leveraging the stainless steel construction and 20.5 kg vertical lift capacity to resist washdown rust.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X175SCM the Right Cylinder?
When sizing this 32 mm bore, stepping down to a 25 mm cylinder drops the 0.5 MPa push force to 245.3 N, whereas moving up to a 40 mm bore increases it to 628.3 N. This model occupies a strong middle ground for medium-force duties. The 175 mm stroke is well within the 500 mm maximum standard stroke, keeping it as a readily available catalogue item. For mounting flexibility, you can pair the CM round end with LB foot brackets, FA flanges, SDB pivot blocks or TC trunnions.
Because it is a double-acting cylinder, the standard MI32X175SCM relies entirely on continuous air pressure to maintain its position. If the air supply drops or the directional valve is centred, the piston will drift, as the TPU bumpers only decelerate the stroke end and do not function as a locking brake. To suspend a load securely during an outage, fit an external rod lock or install a pilot-operated check valve in the air line.
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 MI32X175SCM FAQ
The 32 mm bore operates on a 1/8" air port. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, increasing to 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, the piston will drift if air pressure is lost or the valve is centred. The fixed TPU bumper pads only decelerate the piston near the stroke end and do not act as a brake. You must use an external rod lock or pilot check valve to hold a load securely.
