About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X150U
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MI32X150U is a robust round-body mini cylinder built for demanding automation. It features a 32 mm bore, a 150 mm stroke, and a 1/4 inch air port. The stainless-steel barrel and piston rod provide excellent mild corrosion and washdown resistance, outperforming painted alternatives in damp environments. A 90-degree U back cover allows flexible port and mounting orientation.
This double-acting actuator relies on fixed TPU bumper pads to decelerate the piston at stroke ends, operating smoothly across a 30-800 mm/s speed range. Because it lacks an -S suffix, this specific SKU cannot accept magnetic position switches. For practical sizing, plan for a safe working load of roughly 241 N, which equates to lifting about 20.5 kg vertically with a 2:1 safety margin.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X150U Is Used
Package Diverting
Pushes medium-weight cartons off a sorting line using 402.2 N of thrust, with the stainless build enduring humid washdown periods.
Pallet Gate Control
Actuates a 90-degree safety gate mechanism via the U back cover, handling the 150 mm stroke requirement for pallet routing.
Press Ejection
Ejects formed metal components from a stamping die, relying on fixed TPU pads to absorb end-stroke impact at high cycle rates.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X150U the Right Cylinder?
When sizing this 32 mm bore unit, note it sits between the 25 mm option (245.3 N push at 0.5 MPa) and the larger 40 mm class (628.3 N push). If your application requires position feedback, you must select the -S magnet version to utilize CMSG, DMSG, or EMSG sensors, as this base SKU is unsensored. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion brackets.
Remember that a standard double-acting cylinder drifts when 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 braking lock. To suspend a load safely during an emergency stop, integrate an external rod lock or a pilot-operated check valve. Additionally, ensure your mechanical linkage handles side loads to prevent rod bending over the 150 mm extension.
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 MI32X150U FAQ
This 32 mm bore cylinder features a 1/4 inch port and a 150 mm stroke. 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 force of 82 kgf at 1.0 MPa.
No, because this model lacks the -S suffix, it has no internal magnet and cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for position sensing.
