About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X15U
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavy-duty actuation within a tight 15 mm stroke. The stainless-steel barrel and rod shrug off mild corrosion, making it highly reliable in damp or washdown environments compared to painted alternatives. A 1/8" port supplies the air required for its 32 mm bore.
Plan for roughly 241 N of actual work at 0.5 MPa to maintain optimal performance, which translates to safely lifting about 20.5 kg vertically. The riveted construction keeps the unit compact, while fixed TPU bumper pads absorb the impact at the stroke ends. Because this specific SKU lacks the -S suffix, it cannot accept CMSG, DMSG, or EMSG magnetic sensors.

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 MI32X15U Is Used
Short-Stroke Clamping
Secures heavy metal workpieces in CNC machining fixtures using its 402.2 N push force over a rapid 15 mm travel distance.
Carton Sealing Press
Drives a sealing head down firmly on packaging lines, where the stainless build resists moisture from washdown cleaning.
Parts Ejection
Pushes molded components out of a press bed, utilizing the U-type back cover for 90-degree port routing in tight cells.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X15U the Right Cylinder?
When sizing this 32 mm bore, dropping down to a 25 mm cylinder reduces the push force to 245.3 N at 0.5 MPa, whereas stepping up to a 40 mm bore increases it to 628.3 N. This model features a U-type back cover, orienting the port 90 degrees to suit compact machinery layouts. For mounting flexibility, you can utilize LB foot, FA flange, SDB pivot, or TC trunnion brackets.
Remember that the fixed TPU bumpers only decelerate the piston near the end of travel; they do not function as an adjustable air cushion. If your application requires the rod to stay put during a loss of air pressure or when a valve is centered, you must add an external rod lock or a pilot-operated check valve, as the piston will drift. To add position sensing, select the -S magnet variant instead of this non-magnet SKU.
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 MI32X15U FAQ
This 32 mm bore cylinder features a 1/8" port and a 12 mm rod. 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 force of 82 kgf at 1.0 MPa.
No, the 32 mm bore exceeds the ISO 6432 standard sizes and is simply a round-body mini cylinder. Additionally, this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors; you need the -S variant for position sensing.
