About the Airtac MIC Cushioned Mini Cylinder MIC40X25U
Delivering 628.3 N of push force at 0.5 MPa, this 40 mm bore round-body mini cylinder handles heavy-duty actuation within a compact footprint. The stainless-steel barrel and rod resist mild corrosion and washdown environments. A needle-set variable air cushion at both ends absorbs high-speed end-of-stroke shock, protecting the payload and reducing noise. This specific U-style configuration features a 90-degree rear cover for tailored port and mounting orientation.
Operating at speeds from 30 to 800 mm/s, the unit provides a safe working load of about 377 N, capable of lifting roughly 32 kg vertically with a 2:1 safety margin. It uses a 1/4 inch air port and an M12x1.25 male rod thread. Because this SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG position switches.

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 MIC Cushioned Mini Cylinder MIC40X25U Is Used
High-Speed Diverter
Uses the 628.3 N push force to rapidly deflect heavy packages on a sorting line, relying on the adjustable cushion to prevent impact damage at 800 mm/s.
Carton Sealing Press
Drives a sealing head with a safe working load of 377 N, where the stainless construction handles light washdown and the cushion ensures smooth contact.
Short-Stroke Stamper
Executes 25 mm rapid stamping operations, using the needle-set deceleration to protect tooling and reduce mechanical noise at the bottom of the stroke.
Is the Airtac MIC Cushioned Mini Cylinder MIC40X25U the Right Cylinder?
When sizing this 40 mm bore, stepping down to the MIC32 yields 402.2 N of push at 0.5 MPa, while the MIC40 is the largest available bore in this series with no larger option. The adjustable air cushion is essential here for high-velocity strokes or moving heavy masses, allowing you to dial in the exact deceleration curve. Note that the cushion only slows the piston near stroke end; it does not function as a brake. For vertical or suspended loads that must hold position on air loss, fit an external rod lock or pilot-operated check valve, as the piston will drift otherwise.
Mounting flexibility includes LB foot, FA flange, SDB pivot, and TC trunnion brackets alongside the built-in U back cover. If your application requires end-of-stroke sensing, you must select the -S magnet variant to enable CMSG, DMSG, or EMSG switches.
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 MIC Cushioned Mini Cylinder MIC40X25U FAQ
This 40 mm bore cylinder features a 1/4 inch air 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 force of 128.1 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet. You must select the -S version of the MIC40 to use CMSG, DMSG, or EMSG switches. The adjustable air cushion and stainless steel build are present on both variants.
