About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X325SCM
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles demanding automation tasks with ease. The stainless-steel barrel and piston rod resist mild corrosion, making it highly suitable for damp or washdown environments where painted alternatives fail. A built-in piston magnet comes standard, allowing seamless integration with CMSG, DMSG, or EMSG reed and electronic switches for position sensing.
The CM round end back cover provides a clean rear profile for straightforward mounting. Equipped with fixed TPU bumper pads, the unit decelerates the piston at stroke ends to reduce impact wear. Plan for a safe working load of roughly 241 N, which is about 60 percent of the 0.5 MPa rating. Alternatively, it can vertically lift around 20.5 kg with a 2:1 safety margin, letting you match real part weights directly.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X325SCM Is Used
Package Diverting
Pushes heavy cardboard cartons on a sorting line using the 402.2 N push force, while the stainless build withstands humid packing areas.
Pallet Gate Control
Actuates a 325 mm travel gate mechanism on a palletizing cell, relying on the CM round end for a compact rear pivot installation.
Textile Loom Tensioning
Maintains fabric tension on a weaving machine, using the built-in magnet and DMSG sensors to confirm the 325 mm stroke position.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X325SCM 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 stepping up to a 40 mm bore increases it to 628.3 N. This model offers a 325 mm stroke, which is well within the 500 mm standard limit for this bore size. However, at this extended length, be mindful of side loads and rod-bending moments—ensure adequate guiding to prevent premature seal wear.
Because it is a double-acting actuator, the piston will drift if air pressure is lost or the valve is centered; the TPU bumpers only soften the end-of-stroke impact and do not function as a locking mechanism. To suspend a load safely during an emergency, incorporate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 MI32X325SCM FAQ
This 32 mm bore cylinder features a 1/8 inch air port and a male M10x1.25 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.
The stainless-steel barrel and rod offer excellent mild corrosion resistance for outdoor or washdown settings. However, it does not hold its load if air is lost; the piston drifts, as the fixed TPU bumper pads only decelerate the stroke end. Use a pilot check valve for position holding.
