About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X180SU
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles substantial workloads within a compact footprint. The stainless-steel barrel and piston rod provide mild corrosion resistance, making it highly suitable for damp production environments where painted steel alternatives would degrade. Integrated fixed TPU bumper pads absorb stroke-end impact to protect internal components, operating reliably across a speed range of 30-800 mm/s. Equipped with a 1/8" air port and a 90-degree U back cover, it routes plumbing neatly for tight machinery layouts.
For practical sizing, plan for roughly 241 N of real work at 0.5 MPa, which safely accounts for friction and operational variables. This translates to lifting a 20.5 kg payload vertically when applying a 2:1 safety margin. The built-in piston magnet (-S) directly supports CMSG, DMSG, and EMSG position switches, enabling precise end-of-stroke detection in automated sequences.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X180SU Is Used
Package Diverting Gate
Actuates a heavy routing flap on a logistics sorting line, using the 402.2 N push force to reliably redirect parcels weighing up to 20 kg onto secondary chutes.
Press Pin Insertion
Drives a locating pin into mild steel housings on an assembly fixture, utilizing the 180 mm stroke to clear the workpiece during automated loading and unloading.
Pallet Stacking Pusher
Sweeps layered cardboard components into a stacking cradle, where the stainless construction withstands occasional moisture from refrigerated goods entering the packing zone.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X180SU the Right Cylinder?
When sizing this 32 mm bore, evaluate your force margins carefully: the smaller Ø25 MI generates 245.3 N of push at 0.5 MPa, while the larger Ø40 MI provides 628.3 N. Choose this model when your application demands the 402.2 N output and a 180 mm stroke. Because it lacks an adjustable air cushion, high-speed cycling relies entirely on the fixed TPU bumpers; for heavy dynamic loads at high velocities, consider the MIC variable-cushion variant instead. The 180 mm stroke is well within the 500 mm maximum standard stroke, keeping the unit readily available without made-to-order delays.
Remember that a standard double-acting cylinder drifts if air pressure drops or the control valve centres; the bumpers only soften the end-of-stroke impact and do not function as a braking lock. If your process requires strict position holding on a vertical load, install an external rod lock or a pilot-operated check valve. The 90-degree U back cover simplifies pivot mounting, and the -S magnet ensures compatibility with reed and electronic 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 MI32X180SU FAQ
This 32 mm bore cylinder features a 1/8" air port and a male M10x1.25 rod thread. 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 drops or the directional valve centres. The fixed TPU bumper pads only decelerate the rod near the stroke end and do not act as a lock. For vertical load holding, you must add an external rod lock or a pilot-operated check valve.
