Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X125CA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X125CA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 125mm 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 MFC40X125CA
Delivering 628.3 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavy loads with precision. The riveted SUS304 stainless barrel and aluminium covers resist mild corrosion and washdown, while the JIS-standard body is noticeably shorter than an ISO 6432 cylinder for the same bore and stroke, saving valuable mounting length.
A variable air cushion at both ends lets you dial in the needle valve to absorb end-of-stroke shock at high speeds, protecting your payload from impact. Based on the 0.5 MPa push rating, this actuator yields a safe working load of about 377 N, meaning it can lift roughly 32 kg vertically with a 2:1 safety margin. Note that this specific SKU lacks the -S magnet, so it cannot host CMSG, DMSG, or EMSG sensors.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X125CA Is Used
Heavy Package Diversion
Uses the 628.3 N push force to deflect heavy cartons on a high-speed sorting line, relying on the variable air cushion to halt the 125 mm stroke without slamming.
Press Ejection
Pushes finished metal parts out of a press, where the adjustable end-cushioning protects both the tooling and the component from abrupt shocks at cycle completion.
Pallet Stopper Gate
Acts as a robust stop for loaded pallets, using its 32 kg vertical lift capacity and CA pivot mount to absorb the momentum of incoming goods smoothly.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X125CA the Right Cylinder?
If 628.3 N at 0.5 MPa is more force than your application requires, step down to the MFC32, which provides 402.2 N; since 40 mm is the largest available MFC bore, moving up is not an option. The adjustable air cushion is essential when moving heavy masses at high velocities, as it decelerates the piston smoothly near the stroke end.
This model features a CA rear pivot cover for articulated mounting. Because it is a standard cylinder, it will not hold a load if air pressure drops—the piston drifts, and the cushion only slows travel, acting as a brake. For suspended loads, install an external rod lock or pilot-operated check valve.
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 MFC40X125CA 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, with a theoretical maximum force of 128.1 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet, so it cannot accommodate CMSG, DMSG, or EMSG switches. You would need the -S variant for magnetic sensing; this version relies solely on its SUS304 stainless build and variable air cushion for operation.
