About the Airtac MI25~40 Stainless Steel Mini Cylinder MI40X60UTC
Delivering 628.3 N of push force at 0.5 MPa, the AirTAC MI40X60UTC is a robust double-acting round-body mini cylinder built for demanding actuation. It features a stainless-steel barrel and piston rod that shrug off mild corrosion, giving it a clear edge over painted alternatives in damp or washdown environments. The riveted construction keeps the unit compact, while fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning. A 1/4" port supplies the 16 mm rod for rapid cycling between 30 and 800 mm/s.
For practical sizing, plan for around 377 N of real work at 0.5 MPa, which safely lifts about 32 kg vertically with a 2:1 margin. This specific SKU omits the internal magnet, meaning it cannot host CMSG, DMSG or EMSG sensors; add an -S variant if position feedback is required. The U back cover provides a 90-degree port orientation, and the included TC trunnion mount simplifies pivoting installations.

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 Ø40 bore is a larger, non-ISO-6432 size.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 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 MI40X60UTC Is Used
Pallet Dispenser Pusher
Uses the 628.3 N thrust to separate empty pallets in automated handling lines, relying on the stainless body to endure humid warehouse conditions.
Heavy Package Diverter
Pivots via the TC trunnion to deflect heavy cartons off a main conveyor belt, with the 60 mm stroke providing rapid diversion without overtravel.
Blister Press Ejector
Pushes completed blister packs out of a forming station using a 16 mm rod, where the fixed TPU bumpers quietly arrest the 60 mm stroke.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI40X60UTC the Right Cylinder?
As the largest bore in the series, the MI40X60UTC tops out the range with 628.3 N push and 527.8 N pull at 0.5 MPa. If your application is lighter, stepping down to the Ø32 bore drops the push force to 402.2 N while saving space, but there is no larger standard AirTAC MI size available if you need more power. The 60 mm stroke is well within the 500 mm maximum, keeping the rod highly resistant to bending under moderate side loads.
Because this is a standard double-acting cylinder, the piston will drift if air pressure drops or the valve is centred—the fixed TPU pads only soften the end-of-stroke impact and act as neither a lock nor a brake. To prevent a suspended 32 kg load from falling, integrate an external pilot-operated check valve or a dedicated rod lock. Furthermore, this configuration lacks the -S magnet, so it cannot support magnetic sensing; rely on the TC trunnion and U cover for physical mounting alignment instead.
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 MI40X60UTC FAQ
At 0.5 MPa this 40 mm bore cylinder provides 628.3 N push and 527.8 N pull. At 0.7 MPa it delivers 879.6 N push and 738.9 N pull. The theoretical maximum force is 128.1 kgf at 1.0 MPa. It uses a 1/4" air port and a 16 mm piston rod with an M12x1.25 male thread.
No, this specific SKU lacks the internal magnet required for CMSG, DMSG or EMSG switches; you must specify an -S model for position sensing. For installation, it features a U back cover for 90-degree port orientation and a TC trunnion mount for pivot articulation. It is a round-body mini cylinder rather than an ISO 6432 unit.
