About the Airtac MIC Cushioned Mini Cylinder MIC40X150U
Delivering 628.3 N of push force at 0.5 MPa, this double-acting stainless steel round-body mini cylinder handles heavy-duty actuation. The Ø40 bore operates on a 1/4" port with a Ø16 piston rod and M12x1.25 male thread. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches. A 90-degree U rear cover provides flexible port and mounting orientation.
Twin adjustable air cushions at both stroke ends let you needle-set the deceleration to absorb high-speed shock, protecting your machinery and reducing noise far better than a fixed rubber bumper. The stainless barrel and rod resist mild corrosion and washdown environments. For vertical applications, the 628.3 N push force at 0.5 MPa lifts about 32 kg with a 2:1 safety margin, giving a safe working load of roughly 377 N.

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 MIC40X150U Is Used
Heavy Package Diverting
Pushes dense cartons at high speed across sorting lines, using the adjustable cushion to halt the 150 mm stroke smoothly without jarring the belt.
Pallet Stopper Gate
Acts as a robust stop for loaded pallets, leveraging the 628.3 N push force to arrest momentum while the needle-set cushion absorbs the end impact.
Large Case Sealing
Drives heavy sealing jaws through a 150 mm travel, where the stainless build handles mildly humid packing areas and the cushion prevents jaw bounce.
Is the Airtac MIC Cushioned Mini Cylinder MIC40X150U the Right Cylinder?
When sizing this actuator, step down to the MIC32 bore if your load requires less than 402.2 N of push at 0.5 MPa, or look externally since Ø40 is the largest available MIC round-body mini cylinder. The adjustable end cushions are essential when driving heavy masses at high speeds up to 800 mm/s, as they prevent destructive end-of-stroke impact. Remember that the air cushion only decelerates the piston near the stroke end; it does not function as a brake or lock. If your application must hold a load vertically during air loss, install an external rod lock or pilot-operated check valve. Along with the U back cover, you can mount this cylinder 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 MIC40X150U FAQ
This double-acting cylinder has a 40 mm bore and 150 mm stroke. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, or 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. It uses a 1/4" port, a Ø16 mm rod and an M12x1.25 male rod thread.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG or EMSG switches. You would need the -S variant for sensing. The cylinder features a stainless steel round-body build and adjustable air cushions at both ends to decelerate loads, but it will drift if air pressure is lost.
