Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X225U
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X225U is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 225mm stroke, 1/4" air ports and a SUS304 stainless-steel barrel for mildly corrosive environments. For the same bore and stroke it is shorter than an ISO 6432 cylinder, saving mounting space.

About the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X225U
Delivering 628.3 N of push force at 0.5 MPa, the AirTAC MFC40X225U is a JIS-standard round-body mini cylinder built for demanding actuation. It features a SUS304 stainless barrel and riveted aluminium covers that resist mild corrosion and washdown environments. For the same bore and stroke, this riveted construction is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length.
This double-acting model uses a variable air cushion at both ends; you simply turn the needle valve to soak up high-speed end-of-stroke shock, protecting the load and cutting noise. It provides a safe working load of about 377 N, meaning it lifts roughly 32 kg vertically with a 2:1 safety margin. This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors, and it carries a U flat-end rear cover.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X225U Is Used
Heavy Carton Diversion
Uses the 628.3 N push force to deflect heavy packaged goods on a high-speed sorting line, relying on the adjustable air cushion to prevent harsh impacts at the 225 mm stroke end.
Pallet Flap Folding
Folds large cardboard flaps on automated palletizers where the U flat-end cover mounts flush against the machine frame, saving space compared to standard ISO 6432 units.
Chassis Component Pusher
Shifts heavy metal brackets into welding fixtures; the SUS304 stainless barrel withstands coolant mist while the needle-set cushion decelerates the 16 mm rod smoothly.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X225U the Right Cylinder?
If 628.3 N at 0.5 MPa is too much force, step down to the MFC32, which provides 402.2 N; since 40 mm is the largest available MFC bore, you cannot size up within this series. The adjustable air cushion is essential when driving heavy loads at high speeds, as it decelerates the piston smoothly. Remember that this cushion only slows the piston near the stroke end—it is not a lock or brake. If your application must hold a load vertically during air loss, add an external rod lock or pilot-operated check valve. Furthermore, because this base SKU has no magnet, position sensing is impossible without switching to the -S variant.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/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/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X225U FAQ
This 40 mm bore cylinder has a 1/4" port and a 16 mm rod with an M14x1.5 male thread. It generates 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, and a theoretical maximum of 128.1 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. The cylinder does feature a variable air cushion at both ends to absorb shock and a SUS304 stainless barrel for corrosion resistance.
