About the Airtac MIC Cushioned Mini Cylinder MIC40X140SCM
Delivering 628.3 N of push force at 0.5 MPa, this double-acting stainless round-body mini cylinder tackles heavy-duty tasks. The 40 mm bore uses a 1/4 inch port and a 16 mm rod with an M12x1.25 male thread. A needle-set variable air cushion at both ends absorbs high-speed end-of-stroke shock, protecting your machinery and reducing noise better than a fixed bumper. The stainless steel barrel and rod resist mild corrosion and washdown environments.
For practical sizing, the safe working load is roughly 377 N, which means it lifts about 32 kg vertically with a 2:1 safety margin. The rear CM round cover provides flexible port and mounting orientation. Because it is a 40 mm bore, it is a non-ISO-6432 round-body design, yet it shares the robust riveted construction of the series. The S suffix indicates a built-in piston magnet for position sensing.

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 MIC40X140SCM Is Used
Heavy Package Diversion
Pushes heavy cartons at high speed across transfer lines. The adjustable air cushion prevents harsh impacts that could damage packaging.
Vertical Load Lowering
Handles 32 kg payloads downward. The needle-set cushion slows the descent smoothly at the bottom of the 140 mm stroke.
Washdown Component Shift
Relocates metal parts in mildly corrosive, humid environments. The stainless barrel and rod withstand wet industrial conditions.
Is the Airtac MIC Cushioned Mini Cylinder MIC40X140SCM the Right Cylinder?
When sizing this 40 mm bore, dropping down to a MIC32 saves space but cuts push force to 402.2 N at 0.5 MPa, while no larger MIC bore exists for higher loads. Choose this model when moving heavy loads at high speeds, as the adjustable air cushion is essential for smooth deceleration. For vertical or suspended loads, remember the cushion only decelerates near the stroke end and does not act as a brake; the piston will drift on air loss, so add an external rod lock or pilot check valve.
Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion brackets. The included S magnet enables CMSG, DMSG, or EMSG electronic and reed switches for precise end-position detection. Operating speed ranges from 30 to 800 mm/s.
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 MIC40X140SCM FAQ
This double-acting cylinder features a 1/4 inch port and generates 628.3 N push and 527.8 N pull at 0.5 MPa. At 0.7 MPa it yields 879.6 N push and 738.9 N pull. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
It uses a needle-set variable air cushion at both ends to decelerate loads smoothly near stroke end, but this is not a locking brake. The S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors.
