About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X350R
Delivering 402.2 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles substantial work within a compact riveted footprint. The Ø32 bore operates on a 1/4" port and a Ø12 mm piston rod with an M10x1.25 male thread. Because the bore exceeds standard mini dimensions, it is classified strictly as a round-body mini cylinder rather than an ISO 6432 unit.
The stainless barrel and rod resist mild corrosion, making it superior to painted alternatives in damp production zones. Fixed TPU bumper pads absorb end-of-stroke impact, while the rear R cover provides an axial-in port orientation for neat plumbing. For practical sizing, plan for roughly 241 N of real work at 0.5 MPa, which equates to safely lifting about 20.5 kg vertically with a 2:1 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 MI32X350R Is Used
Package Diverting Gate
Actuates a heavy routing flap on a logistics conveyor, utilizing the 402.2 N push force to redirect mid-weight parcels reliably.
Volumetric Fill Valve
Drives a large dosing piston for liquid filling machines, where the 350 mm stroke accommodates deep container variations.
Pneumatic Clamping Arm
Secures thick wooden workpieces in a furniture assembly jig, taking advantage of the robust Ø12 mm rod and axial R rear port plumbing.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X350R the Right Cylinder?
When sizing this 350 mm stroke unit, verify your load against the 402.2 N push and 345.6 N pull ratings at 0.5 MPa. If your application requires less force, the Ø25 bore offers 245.3 N; for heavier demands, the Ø40 bore provides 628.3 N. The extended 350 mm travel demands careful guidance to prevent rod bending under side loads. This specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG or EMSG position switches—order the -S variant if sensing is required. Furthermore, standard TPU bumpers only decelerate the stroke end; a plain cylinder drifts when air is removed, so fit an external rod lock or pilot check valve to hold a suspended load.
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 MI32X350R FAQ
This double-acting cylinder uses a 1/4" port and generates 402.2 N push and 345.6 N pull at 0.5 MPa. At 0.7 MPa, push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, this SKU lacks the -S magnet required for CMSG, DMSG or EMSG switches. It also features fixed TPU bumper pads for end-of-stroke deceleration rather than the adjustable air cushion found on MIC variants.
