About the Airtac MIC Cushioned Mini Cylinder MIC40X225U
Delivering robust linear motion, this double-acting round-body mini cylinder features a stainless-steel barrel and rod for mild washdown resistance. A needle-set variable air cushion at both ends absorbs high-speed end-of-stroke shock, protecting your payload and reducing noise. The 1/4" port and M12x1.25 male rod thread equip this Ø40 bore unit for heavy-duty tasks.
Operating across a 30-800 mm/s speed range, it generates 628.3 N of push force at 0.5 MPa. This translates to a safe working load of about 377 N, or roughly 32 kg of vertical lift with a 2:1 safety margin. This specific SKU lacks a magnet and cannot accept position sensors; adding the -S variant enables CMSG, DMSG, or EMSG 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 MIC40X225U Is Used
Heavy Carton Diverting
Pushes heavy packaged goods at high speed across transfer lines, using the adjustable cushion to halt the 628N stroke smoothly without smashing the payload.
Vertical Press Assembly
Drives small pressing and seating tasks, safely lowering up to 32 kg loads with a 2:1 margin before gently decelerating at the stroke base.
Film Roll Tensioning
Maintains robust tensioning force on packaging machinery, where the stainless build resists mild moisture and the cushion prevents sudden jerks at stroke end.
Is the Airtac MIC Cushioned Mini Cylinder MIC40X225U the Right Cylinder?
When sizing this 628.3 N @0.5 MPa unit against the range, step down to the Ø32 bore for 402.2 N if the load is lighter, as no larger MIC bore exists. The adjustable cushion proves essential when driving heavy loads at high speeds, allowing you to dial in deceleration. Note that the cushion only slows the piston near stroke end and acts as a brake; the rod will drift if air pressure drops. Use an external rod lock or pilot check valve for secure load holding.
This model includes a U-type 90-degree rear cover for specific mounting orientation. Because it lacks the -S magnet, it cannot support magnetic sensing. You can adapt installation using LB foot, FA flange, SDB pivot, or TC trunnion brackets.
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 MIC40X225U FAQ
This Ø40 bore cylinder features a 1/4" port and an M12x1.25 male rod thread. It delivers 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 and cannot accept CMSG, DMSG, or EMSG switches; you must select the -S variant for sensing. It features a stainless-steel round-body build with adjustable air cushions at both ends to decelerate high-speed loads.
