About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X150R
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavier automation tasks with a 150 mm stroke. The stainless-steel barrel and Ø12 mm piston rod resist mild corrosion and washdown, outperforming painted alternatives in damp environments. Its riveted construction keeps the unit compact while fixed TPU bumper pads absorb end-of-stroke impact.
Because this 32 mm bore lacks an -S suffix, it cannot accept CMSG, DMSG, or EMSG magnetic sensors. The R back cover features an axial-in port orientation, and the 1/8" air connection matches the bore size. Plan for roughly 241 N of actual work at 0.5 MPa, which means you can safely lift 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 MI32X150R Is Used
Package Diverting
Actuates routing gates on packaging lines, using its 402.2 N thrust to push heavy cartons smoothly onto secondary belts.
Pallet Stopper Arms
Controls pallet flow in distribution hubs, raising and lowering stop blades that handle substantial inertial loads.
Clamp Fixtures
Secures metal or wood workpieces during machining operations, applying reliable clamping pressure via the 1/8" port.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X150R the Right Cylinder?
Sizing around the 32 mm bore means checking both neighbours: the Ø25 delivers 245.3 N push while the Ø40 provides 628.3 N, both at 0.5 MPa. If your load drops when air is lost or the valve centres, remember this cylinder drifts—the TPU bumpers only decelerate the stroke end, so add an external rod lock or pilot check valve to hold position. The 150 mm stroke is well within the 500 mm maximum, but keep side-loads minimal to avoid rod bending.
This base SKU has no magnet, so position sensing is impossible unless you upgrade to an -S version. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion brackets, complemented by CA, U, R, or CM back covers.
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 MI32X150R FAQ
This 32 mm bore cylinder features a 1/8" port and an M10x1.25 male rod thread. 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 of 82 kgf at 1.0 MPa.
No, the Ø32 bore exceeds ISO 6432 dimensions, so it is strictly a round-body mini cylinder. Additionally, this specific SKU lacks a magnet, meaning it cannot support CMSG, DMSG, or EMSG sensors; you would need the -S variant for position sensing.
