Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X225CM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X225CM 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 MFC40X225CM
Delivering 628.3 N of push force at 0.5 MPa, the AirTAC MFC40X225CM is a JIS-standard round-body mini cylinder built for demanding actuation. A variable air cushion at both ends allows you to dial in the needle valve to absorb high-speed end-of-stroke shock, protecting the payload and reducing noise. The riveted aluminium covers and SUS304 stainless barrel resist mild corrosion and washdown, while the CM round-end rear cover suits compact installations. For the same bore and stroke, this unit is notably shorter than an ISO 6432 cylinder.
This double-acting actuator features a 40 mm bore, a 16 mm piston rod, and a 1/4" port. Based on the 0.5 MPa push rating, it handles a safe working load of roughly 377 N and lifts about 32 kg vertically with a 2:1 safety margin. Note that this specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG position switches; you would need the -S variant for sensing.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X225CM Is Used
Heavy Carton Diversion
Uses the 628.3 N push force to deflect heavy packaged goods on a high-speed sorting line, with the variable air cushion preventing harsh slams at the end of the 225 mm stroke.
Press Ejection
Pushes finished metal parts out of a press area, relying on the SUS304 stainless barrel to withstand occasional coolant spray and the cushion to decelerate the 16 mm rod smoothly.
Pallet Stopper Gate
Acts as a robust stop for loaded pallets, lifting about 32 kg vertically with a 2:1 margin while the CM round-end cover keeps the rear profile compact.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X225CM the Right Cylinder?
When sizing this 40 mm bore, step down to the MFC32 if your application only requires 402.2 N of push force at 0.5 MPa, as no larger MFC bore exists for heavier loads. The adjustable air cushion is essential when cycling at high speeds or moving substantial mass, letting you tune the deceleration to prevent harsh impacts. Remember that the cushion only slows the piston near the end of the stroke—it is not a braking device.
Because this base SKU has no magnet, you cannot mount reed or solid-state sensors for position feedback; select an MFC40X225CM-S if your control system requires end-of-stroke confirmation. Furthermore, a standard cylinder will drift if air pressure drops or the valve is centred. To suspend a load safely mid-stroke, install an external rod lock or a pilot-operated check valve rather than relying on the cushion. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion.
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 MFC40X225CM FAQ
This 40 mm bore double-acting cylinder has a 1/4" port and a 16 mm rod. 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, with a theoretical maximum of 128.1 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so CMSG, DMSG, or EMSG switches cannot be used. You must order the -S variant for position sensing. The variable air cushion at both ends only decelerates the piston near stroke end and does not lock or hold the load.
