About the Airtac MI25~40 Stainless Steel Mini Cylinder MI40X600SCMTC
Delivering 628.3 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavy-duty actuation tasks. The stainless-steel barrel and Ø16 mm piston rod resist mild corrosion and washdown, outperforming painted alternatives in damp environments. It features a CM round rear cover and a 1/4" port.
This specific configuration includes a 600 mm stroke, which exceeds the 500 mm standard maximum for the Ø40 bore, making it a made-to-order item. The built-in magnet (-S) supports CMSG, DMSG and EMSG sensors for position detection. Fixed TPU bumper pads absorb stroke-end impact. Plan for roughly 377 N of actual work at 0.5 MPa, which safely lifts about 32 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 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 MI40X600SCMTC Is Used
Heavy Package Diversion
Pushes heavy cartons on packaging lines using its 628.3 N thrust, while the stainless build survives humid washdown environments.
Long-Reach Material Gate
Utilizes the non-standard 600 mm stroke to actuate a distant sorting gate, with the TC trunnion accommodating structural pivot.
Pallet Component Pusher
Lifts or shoves roughly 32 kg metal fixtures into position vertically, relying on the Ø16 rod to maintain rigidity over the extended length.
Is the Airtac MI25~40 Stainless Steel Mini Cylinder MI40X600SCMTC the Right Cylinder?
When sizing this actuator, the Ø32 bore offers 402.2 N push at 0.5 MPa if you need less force, while the Ø40 is the largest available in this series. Because the 600 mm stroke is non-standard and long, carefully manage side loads to prevent rod bending and premature seal wear. The included TC trunnion mount pairs with the CM round end to handle pivoting articulation smoothly.
Remember that a standard cylinder drifts when air is lost or the valve is centred, as the fixed bumpers only decelerate the end of travel rather than locking the load. To suspend a load securely, install an external rod lock or a pilot-operated check valve.
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 MI40X600SCMTC FAQ
This Ø40 bore cylinder features a 1/4" port and an M12x1.25 male rod thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum of 128.1 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in piston magnet compatible with CMSG, DMSG and EMSG switches. The stroke end is decelerated by fixed TPU bumper pads rather than an adjustable air cushion. Note that the 600 mm stroke is a non-standard, made-to-order length exceeding the 500 mm maximum.
