Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X225CA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X225CA 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 MFC40X225CA
Delivering 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore mini cylinder handles heavy loads with precision. The MFC40X225CA features a variable air cushion at both ends, allowing you to dial in a needle valve to absorb end-of-stroke shock during high-speed cycles. This riveted round-body actuator uses a SUS304 stainless barrel and aluminium covers, offering excellent mild corrosion and washdown resistance.
For the same bore and stroke, the JIS-standard body is noticeably shorter than a comparable ISO 6432 cylinder, saving valuable machine space. Equipped with a CA rear pivot cover and a 1/4" port, it yields a safe working load of roughly 377 N. In a vertical setup, it lifts about 32 kg with a 2:1 safety margin. Note that this specific SKU lacks a magnet, so it cannot host CMSG, DMSG, or EMSG sensors without switching to an -S variant.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X225CA Is Used
Heavy Package Diversion
Uses the 628.3 N push force to deflect heavy cartons at high speed, relying on the adjustable air cushion to prevent harsh slamming at the 225 mm stroke end.
Press Ejection System
Pushes finished metal parts out of a press, where the SUS304 stainless barrel withstands mild coolant spray and the cushion needle dials out impact shock.
Pallet Stopper Gate
Acts as a robust stop for loaded pallets, using the CA pivot mount to absorb side loads while the variable cushion softens the deceleration of heavy masses.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X225CA the Right Cylinder?
When sizing this 40 mm bore actuator, 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 moving heavy masses at high velocities, as it decelerates the piston smoothly near the stroke ends. Remember that this cushion only reduces impact speed; it does not function as a brake.
Because a standard cylinder cannot hold position upon air loss or valve centering, the piston will drift, requiring an external rod lock or pilot-operated check valve for suspended loads. This model includes a CA rear pivot cover for clevis mounting. Since it lacks the -S magnet option, position sensing is unavailable on this particular unit.
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 MFC40X225CA FAQ
This 40 mm bore cylinder features 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, 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 a magnet, so it cannot support CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. Additionally, its variable air cushion only decelerates the load near the stroke end and does not lock or hold the position if air pressure is lost.
