About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X50R
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavier duty cycles where smaller bores stall. The stainless-steel barrel and Ø12 mm piston rod shrug off mild corrosion, making it highly suitable for damp washdown environments. An R back cover configures the port for axial-in routing to tidy up tight machinery plumbing, while fixed TPU bumper pads absorb the impact at stroke ends.
This 32 mm bore unit runs on a 1/8 inch air port and operates at speeds from 30-800 mm/s. Because it lacks the -S suffix, this specific SKU cannot host CMSG, DMSG or EMSG magnetic sensors. For sizing practicality, plan for roughly 241 N of actual work at 0.5 MPa, which means it lifts about 20.5 kg vertically with a safe 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 MI32X50R Is Used
Package Divert Gate
Actuates a heavy routing flap on a logistics conveyor, using its 402.2 N push force to swing heavy cartons onto secondary sorting lanes.
Stamping Pin Press
Drives a short 50 mm stroke pin marker to emboss serial numbers into aluminium extrusions on an automated fabrication line.
Clamp Arm Actuator
Secures heavy steel plate during CNC machining, relying on the 345.6 N pull force at 0.5 MPa to retract the holding arm clear of the spindle.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X50R the Right Cylinder?
When sizing this 32 mm bore actuator, compare it against its neighbours: a 25 mm bore yields 245.3 N of push at 0.5 MPa, whereas stepping up to a 40 mm bore provides 628.3 N. The 50 mm stroke here is well within the 500 mm maximum, keeping the rod rigid with minimal bending risk. The 1/8 inch port and M10x1.25 male rod thread are fixed by the bore size. Remember that fixed TPU bumpers only decelerate the end of travel; they do not act as a brake. If your application must hold a vertical load when air pressure drops or the valve centres, you must add an external rod lock or a pilot-operated check valve, as the piston will drift.
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 MI32X50R FAQ
This 32 mm bore cylinder features a 1/8 inch air 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, this specific SKU lacks the internal magnet. You must purchase the -S variant to use CMSG, DMSG or EMSG switches. Additionally, note that Ø32 is a non-ISO-6432 round-body size, and the fixed TPU bumpers only decelerate the stroke end rather than providing adjustable cushioning.
