About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X450SR
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 Ø12 mm piston rod provide excellent mild corrosion and washdown resistance, outperforming painted alternatives in damp environments. Equipped with a 1/8" port and an R axial-in rear cover, it integrates smoothly into existing pneumatic setups.
It features fixed TPU bumper pads that decelerate the piston at stroke ends to reduce impact wear. The built-in -S magnet allows direct mounting of CMSG, DMSG, or EMSG switches for position sensing. For practical sizing, plan for a safe working load of roughly 241 N, which comfortably lifts 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 MI32X450SR Is Used
Heavy Package Diversion
Pushes heavier cartons on packaging lines using its 402.2 N push force, while the stainless build withstands occasional washdowns.
Pallet Gate Operation
Actuates 450 mm stroke gating mechanisms to route pallets, relying on the R axial-in port for tight manifold mounting.
Textile Loom Tensioning
Maintains fabric tension in humid production areas, using the -S magnet and DMSG sensors to confirm material feed positions.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X450SR the Right Cylinder?
When sizing this 32 mm bore, compare it against the 25 mm option (245.3 N push @0.5 MPa) or the larger 40 mm bore (628.3 N push @0.5 MPa) to match your exact force requirements. The 450 mm stroke is well within the 500 mm maximum standard stroke limit, but at this extended length side loads can induce rod bending; ensure proper guiding to prevent premature seal wear.
Because this is a double-acting cylinder, it does not hold its position if air pressure drops or the valve is centered—the piston will drift. The TPU bumpers only soften the end-of-stroke impact and act as neither a lock nor a brake. For suspended or vertical loads that must remain fixed during air loss, incorporate an external rod lock or a pilot-operated check valve into your 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 MI32X450SR FAQ
This 32 mm bore cylinder features a 1/8" 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.
No, the Ø32 bore is a non-ISO-6432 round-body mini cylinder, so it uses its own mounting interface rather than standard mini brackets. It uses fixed TPU bumper pads for deceleration, not an adjustable air cushion (which requires the MIC variant).
