About the Airtac MIC Cushioned Mini Cylinder MIC40X20CM
Delivering 628.3 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavy-duty tasks within a compact footprint. The stainless-steel barrel and Ø16 mm piston rod resist mild corrosion and washdown environments. Equipped with a CM round rear cover, it features a 1/4" air port and an M12x1.25 male rod thread. Operating at speeds from 30 to 800 mm/s, it yields a safe working load of about 377 N and can vertically lift roughly 32 kg with a 2:1 margin.
The defining feature of the MIC series is the adjustable air cushion at both ends. By turning a needle valve, you tune the deceleration to absorb end-of-stroke shock at high speeds, protecting the load and reducing noise far better than a fixed bumper. Note that this specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG sensors for position detection.

Where the Airtac MIC Cushioned Mini Cylinder MIC40X20CM Is Used
Heavy Press Damping
Drives a 30 kg stamping head downward at high speed, relying on the adjustable air cushion to decelerate the 628.3 N push force smoothly without slamming.
Pallet Diverter
Pushes loaded pallets off a main line using its 377 N safe working load capacity, with the cushion needle tuned to prevent load spillage at stroke end.
Carton Sealing Clamp
Holds heavy cartons steady during the sealing process, utilizing the stainless steel construction to endure occasional washdowns in food packaging areas.
Is the Airtac MIC Cushioned Mini Cylinder MIC40X20CM the Right Cylinder?
When sizing this 40 mm bore actuator, compare it against the adjacent MIC32 option, which provides 402.2 N of push force at 0.5 MPa. Since Ø40 is the largest available bore in this series, moving up in force class requires a different cylinder family entirely. Choose this model when driving heavier payloads at high velocities where the dual adjustable air cushions are essential for smooth stops.
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 or valve centering, the piston will drift, so you must add an external rod lock or pilot-operated check valve. For mounting flexibility without a sensor, utilize 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 MIC40X20CM FAQ
This 40 mm bore cylinder features a 1/4" air port and an M12x1.25 male rod thread. 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 -S magnet option, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. The adjustable air cushions at both ends only serve to decelerate the load near stroke end and do not lock or hold the position.
