About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X35SCM
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MI32X35SCM is a double-acting round-body mini cylinder built for demanding actuation. Its stainless-steel barrel and Ø12 mm rod shrug off mild corrosion, making it highly suitable for damp or washdown environments where painted steel alternatives quickly degrade. The riveted construction keeps the unit compact, while fixed TPU bumper pads absorb the impact at stroke extremes to protect your tooling.
Equipped with a 1/8" port and an M10x1.25 male rod thread, this 32 mm bore model integrates smoothly into heavier pneumatic setups. The built-in piston magnet (-S) enables direct mounting of CMSG, DMSG, or EMSG switches for precise position sensing. For practical sizing, plan for a safe working load of roughly 241 N, which translates to lifting about 20.5 kg vertically with a 2:1 safety margin. The CM round end cover completes the rear assembly for straightforward installation.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X35SCM Is Used
Package Diverting Gate
Actuates a heavy routing flap on a logistics conveyor, utilizing the 402.2 N push force to reliably redirect parcels weighing up to 20 kg.
Blow Mold Clamp
Secures plastic preforms in a beverage plant bottling line, where the stainless build withstands routine washdowns and the CM cover simplifies rear pivot mounting.
Press Pin Insertion
Drives a 12 mm rod down to seat metal dowels in an aluminum housing, relying on the short 35 mm stroke for a compact, high-rigidity assembly station.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X35SCM the Right Cylinder?
When sizing this 32 mm bore unit, compare it against its neighbours: a 25 mm cylinder provides 245.3 N of push at 0.5 MPa, while stepping up to a 40 mm bore yields 628.3 N. Choose the MI32X35SCM when your application requires that mid-range 402.2 N thrust. The short 35 mm stroke minimizes rod bending and side-load risks, though you should still ensure rigid mounting using LB foot, FA flange, or TC trunnion brackets.
Remember that a standard double-acting cylinder drifts if air pressure drops or the valve is centred; the TPU bumpers only decelerate the end of stroke and will not act as a brake. If your process requires strict load holding on air loss, install an external rod lock or a pilot-operated check valve. Additionally, because this SKU includes the -S magnet, it is fully ready to accept CMSG, DMSG, or EMSG 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 MI32X35SCM FAQ
This 32 mm bore cylinder uses a 1/8" port and features 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, the piston will drift if air is lost or the directional valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not function as a locking brake. For vertical load holding, you must add an external rod lock or a pilot-operated check valve.
