About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X500SU
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MI32X500SU is a robust double-acting round-body mini cylinder built for demanding automation. Its stainless-steel barrel and Ø12 mm piston rod shrug off mild corrosion, making it highly suitable for damp washdown environments where painted steel alternatives quickly degrade. The riveted construction keeps the unit compact while fixed TPU bumper pads absorb impact energy at the stroke extremes.
Equipped with a built-in piston magnet (-S), this unit supports CMSG, DMSG and EMSG reed or electronic switches for precise position sensing. The U-style 90-degree rear cover simplifies lateral mounting, and the 1/4" port handles the air volume needed for a 500 mm extension. 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.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G. Note: the Ø32 bore is a larger, non-ISO-6432 size.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X500SU Is Used
Pallet Diverting Gate
Actuates heavy routing flaps on packaging lines, using its 402.2 N thrust to push loaded pallets onto secondary conveyors without stalling.
Vacuum Lifter Lowering
Lowers suction cup assemblies in automated wood panel handling, safely managing a 20.5 kg vertical load margin across the 500 mm travel.
Textile Dye Press
Provides steady clamping pressure on fabric dyeing machinery, where the stainless construction resists the humid, chemically aggressive atmosphere.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X500SU the Right Cylinder?
Choosing this 32 mm bore makes sense when the 245.3 N push of a Ø25 cylinder is insufficient, but you want to avoid the larger 628.3 N footprint of a Ø40 model. Because this SKU features a 500 mm stroke, carefully manage side loads to prevent rod bending and premature seal wear. The integrated magnet pairs directly with CMSG, DMSG or EMSG sensors for end-of-stroke confirmation.
Remember that fixed TPU bumpers only decelerate the piston near the end of travel; they do not act as a brake. If air pressure drops or the valve is centred, the rod will drift and drop the load. To maintain vertical position safely, install an external rod lock or a pilot-operated check valve in 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 MI32X500SU FAQ
This 32 mm bore cylinder features a 1/4" port and generates 402.2 N push / 345.6 N pull at 0.5 MPa, and 563 N push / 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
Yes to sensors: the -S suffix means a magnet is built-in, allowing CMSG, DMSG and EMSG switches. However, there is no adjustable air cushion; it relies on fixed TPU bumper pads to decelerate the stroke end. For adjustable cushioning, look at the MIC variant.
