About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X160U
Delivering a robust 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles demanding actuation tasks. The stainless-steel barrel and piston rod provide mild corrosion resistance, making it highly suitable for damp environments where painted steel alternatives quickly degrade. A 1/4" port supplies the air, while fixed TPU bumper pads absorb the impact at stroke extremes to protect the mechanism.
Because the bore exceeds the standard mini interface, this Ø32 unit is classified strictly as a round-body mini cylinder rather than an ISO 6432 component. It yields a practical safe working load of roughly 241 N, which translates to lifting a 20.5 kg mass vertically with a 2:1 safety margin. This specific configuration includes a U-style 90-degree rear cover for perpendicular mounting, and because it lacks the -S suffix, it cannot accept CMSG, DMSG or EMSG magnetic sensors.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X160U Is Used
Package Diverting Gate
Actuates a heavy routing flap on a logistics conveyor belt, utilizing the 402.2 N push force to redirect medium-weight parcels reliably at high speeds.
Textile Loom Tensioning
Maintains precise tension on weaving yarns in a humid textile mill, leveraging the stainless-steel construction to resist persistent moisture and lint buildup.
Pallet Stacking Pusher
Extends 160 mm to push cardboard cartons onto a stacking platform, with the U-style 90-degree rear cover allowing a compact perpendicular mounting bracket.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X160U the Right Cylinder?
When sizing this 160 mm stroke model, verify your actual payload against the 402.2 N push capacity at 0.5 MPa. If your application requires less force, stepping down to the Ø25 bore provides 245.3 N, whereas moving up to the Ø40 bore yields 628.3 N for heavier loads. The 160 mm stroke is well within the 500 mm maximum standard stroke for this bore, keeping the unit as a readily available standard item.
Keep in mind that the fixed TPU bumpers only decelerate the piston near the end of travel; they do not function as an adjustable air cushion. If air pressure drops or the valve is centred, the piston will drift, so you must integrate an external rod lock or a pilot-operated check valve to hold a suspended load securely. Furthermore, the absence of a magnet means position sensing is impossible on this specific SKU without upgrading to the -S variant.
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 MI32X160U FAQ
This double-acting cylinder features a 1/4" air port and generates 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, because this specific model lacks the -S suffix, it has no internal magnet and cannot accept CMSG, DMSG, or EMSG switches. You would need to select the -S variant of this round-body mini cylinder to enable magnetic position sensing.
