About the Airtac MIC Cushioned Mini Cylinder MIC40X30CM
Delivering 628.3 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles heavy-duty actuation within a compact footprint. The Ø40 mm bore operates on a 1/4" port and features a robust Ø16 mm piston rod with an M12x1.25 male thread. A defining trait of the MIC series is the adjustable air cushion at both ends, allowing you to tune deceleration to eliminate end-of-stroke bang during high-speed cycles. The CM round rear cover provides a clean, versatile mounting interface for tight machinery layouts.
Built with a stainless barrel and rod, the unit resists mild corrosion and washdown environments. Because this specific SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG sensors. For sizing context, the 628.3 N output translates to a safe working load of roughly 377 N, or the ability to lift about 32 kg vertically with a 2:1 safety margin.

Where the Airtac MIC Cushioned Mini Cylinder MIC40X30CM Is Used
Heavy Package Diversion
Uses the 628.3 N thrust to push heavy cartons off a high-speed main line, relying on the tuned air cushions to stop the 30 mm stroke smoothly without jarring the mechanism.
Pallet Flap Folding
Drives stiff cardboard flaps down on an automated packing line, where the stainless construction handles dusty environments and the cushions prevent bounce at cycle end.
Stamping Pin Actuation
Delivers the force needed to depress heavy stamping pins into metal sheets, using the 1/4" port for rapid air exchange to maintain high production rates.
Is the Airtac MIC Cushioned Mini Cylinder MIC40X30CM the Right Cylinder?
When sizing this actuator, look at the neighboring bores in the range. Stepping down to the Ø32 bore drops the 0.5 MPa push force to 402.2 N, while the Ø40 shown here provides 628.3 N. As the largest bore available in the MIC family, there is no larger cushioned option. The adjustable needle cushions are essential if you are moving heavier masses at high speeds, as they smoothly decelerate the load without slamming. Keep in mind the cushion only slows the piston near the stroke end; it does not function as a brake. If your application must hold a load vertically during air loss, install an external rod lock or pilot check valve.
Mounting flexibility is extensive, with options including LB foot, FA flange, SDB pivot-block, and TC trunnion brackets. Because this base model has no internal magnet, position sensing is not possible without switching to the -S variant. You can pair it with related types like the MID double-rod or MIJ adjustable-stroke cylinders if your motion control requirements change.
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 MIC40X30CM FAQ
This Ø40 mm cylinder features a 1/4" port and a Ø16 mm rod. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, increasing to 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
No, this specific SKU does not include the internal magnet required for sensing. You must select the -S version of the MIC40 to mount CMSG, DMSG, or EMSG switches. The adjustable air cushions and stainless steel build remain standard across both variants.
