About the Airtac MIC Cushioned Mini Cylinder MIC40X150SU
Delivering 628.3 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavy-duty actuation with precision. The MIC40X150SU features a stainless-steel barrel and rod that resist mild corrosion and washdown environments. A 1/4 inch port supplies the air, driving an 800 mm/s maximum speed.
Twin adjustable air cushions at both ends allow you to needle-set the deceleration, soaking up end-of-stroke shock to protect heavy loads and cut noise. The built-in magnet (-S) enables CMSG, DMSG, or EMSG position sensing, while the U back cover provides a 90-degree mounting orientation. With a 628.3 N push rating, it yields a safe working load of about 377 N, lifting roughly 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 MIC Cushioned Mini Cylinder MIC40X150SU Is Used
Heavy Package Diversion
Uses the 628.3 N push force to deflect heavy cartons at 800 mm/s, relying on adjustable air cushions to prevent harsh end-of-stroke impacts.
Vertical Film Sealing
Lifts sealing heads weighing up to 32 kg with a 2:1 safety margin, while the stainless build withstands washdown cleaning cycles.
Stamping Press Feed
Pushes metal blanks into a press, using the 1/4 inch port for rapid cycling and the U back cover for a compact 90-degree mount.
Is the Airtac MIC Cushioned Mini Cylinder MIC40X150SU the Right Cylinder?
When sizing this 40 mm bore unit, stepping down to a MIC32 bore drops the 0.5 MPa push force to 402.2 N, whereas no larger MIC bore exists. Choose this model when moving heavy masses at high speed, as the needle-set air cushions are essential for smooth stops. Note that the cushion only decelerates near the stroke end; it does not act as a brake. If you need to hold a load vertically during air loss, install an external rod lock or pilot check valve, because the piston will drift. The -S magnet supports CMSG/DMSG/EMSG sensors, and you can mount via LB foot, FA flange, SDB pivot, or TC trunnion.
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 MIC40X150SU FAQ
This 40 mm bore cylinder features a 1/4 inch 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.
The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors. The adjustable air cushion only decelerates the piston near stroke end; it is not a lock. For vertical load holding on air loss, you must add an external rod lock or pilot check valve.
