Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X225SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X225SCM 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 MFC40X225SCM
Delivering 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore mini cylinder tackles heavy loads with precision. The MFC40X225SCM features a variable air cushion at both ends, allowing you to tune a needle valve to absorb high-speed end-of-stroke shock, protecting your machinery and reducing noise far better than a fixed bumper.
Built with a SUS304 stainless barrel and riveted aluminium covers, the JIS-standard round-body construction resists mild corrosion and washdown environments. For the same bore and stroke, this design is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length. Equipped with a 1/4" port, an M14x1.5 male rod thread, and a CM round-end rear cover, it includes the -S magnet for CMSG/DMSG/EMSG sensors. Based on the 0.5 MPa push rating, it handles a safe working load of roughly 377 N, lifting about 32 kg vertically with a 2:1 safety margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X225SCM Is Used
Heavy Package Diversion
Uses the 628.3 N push force to positively redirect heavy cartons on a high-speed sorting line, with the tuned air cushion preventing harsh slams at the 225 mm stroke end.
Pallet Flap Folding
Drives large cardboard flaps down on an automated packer, relying on the SUS304 stainless barrel to withstand occasional washdowns during facility cleaning.
Vertical Lift Gate
Raises and lowers a 30 kg access gate, safely managing the load via the variable cushion while the compact JIS body minimizes the required headroom.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X225SCM the Right Cylinder?
When sizing this 40 mm bore model, step down to the MFC32 if your application only requires 402.2 N of push force at 0.5 MPa, as 40 mm is the largest available bore in the MFC family. The adjustable air cushion is essential when driving heavy loads at high speeds up to 800 mm/s, letting you dial in the exact deceleration needed to prevent impact damage.
Remember that the air cushion only decelerates the piston near the stroke end and does not function as a brake. If your system loses air pressure, the piston will drift, so you must add an external rod lock or pilot-operated check valve to hold a suspended load safely. The included -S magnet enables solid state or reed switch mounting, while options like LB foot, FA flange, or TC trunnion fittings adapt it to your frame.
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 MFC40X225SCM FAQ
This 40 mm bore cylinder features a 1/4" port and an M14x1.5 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, with a theoretical maximum force of 128.1 kgf at 1.0 MPa.
No, the variable air cushion only decelerates the piston near the end of the stroke and acts purely as a shock absorber, never as a lock or brake. If air is lost, the piston will drift, so you must fit an external rod lock or pilot check valve to hold suspended loads. The built-in -S magnet supports CMSG, DMSG, and EMSG sensors for position tracking.
