About the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X15R
Generating 402.2 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles heavy short-stroke tasks. The riveted construction uses a stainless barrel and rod to resist mild corrosion in damp or washdown environments. It features a 1/8 inch air port and a rear R cover with an axial-in port orientation for tight spatial constraints. Fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning.
For practical sizing, plan for roughly 241 N of real work at 0.5 MPa, which translates to safely lifting about 20.5 kg vertically with a 2:1 margin. Note that this specific SKU lacks the -S magnet, meaning it cannot host CMSG, DMSG or EMSG reed switches. If your sequence control requires position feedback, you must select the -S variant instead.

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 MI32X15R Is Used
Heavy-Duty Stamping Pin
Drives a robust 15 mm stamping action in automated metal forming lines, utilising its 402.2 N push force to mark or dimple thick plate materials reliably.
Pneumatic Parts Clamp
Secures heavy machined components inside CNC fixturing, where the stainless steel construction prevents coolant washdown from degrading the barrel.
Package Divert Blade
Snaps out rapidly to deflect bulky cartons on a sorting conveyor, with the short stroke ensuring a fast cycling response without rod buckling risks.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI32X15R the Right Cylinder?
When sizing this 32 mm bore, the smaller Ø25 generates 245.3 N of push at 0.5 MPa, while the larger Ø40 provides 628.3 N. This 15 mm stroke is ideal for high-force clamping or ejecting within a tiny footprint. Because the standard MI uses fixed TPU bumpers rather than an adjustable air cushion, consider the MIC variant if your application demands variable end-of-stroke deceleration at high speeds. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion brackets.
This model uses an R back cover with an axial-in port, directing plumbing straight back to save side clearance. The piston will drift if air pressure drops or the valve is centred, as the bumper pads only soften the stroke end rather than locking the rod. To suspend a load safely during an air loss event, install an external rod lock or a pilot-operated check valve in the system.
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 MI32X15R FAQ
This 32 mm bore cylinder features a 1/8 inch air port and a Ø12 mm piston rod. At 0.5 MPa it pushes with 402.2 N and pulls with 345.6 N. At 0.7 MPa the push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet option, so it cannot accept CMSG, DMSG or EMSG switches. You would need to order the -S variant for position sensing. It is a round-body mini cylinder with fixed TPU bumper pads rather than an adjustable air cushion.
