Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X220SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X220SCA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 220mm 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 MFC40X220SCA
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy loads with precision. The MFC40X220SCA features a variable air cushion at both ends, allowing you to dial in a needle valve to absorb high-speed end-of-stroke shock, protecting your machinery and reducing noise far better than a fixed bumper. Its SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown environments.
For the same bore and stroke, the MFC body is notably shorter than an ISO 6432 cylinder, saving valuable mounting length without sacrificing power. Equipped with a 1/4" port and an M14x1.5 male rod thread, it is built for robust actuation. The integrated -S magnet enables position sensing with CMSG, DMSG, or EMSG switches, while the CA back cover provides a rear pivot mount. Based on the 0.5 MPa push rating, it offers a safe working load of roughly 377 N, lifting about 32 kg vertically with a 2:1 margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X220SCA Is Used
Heavy Stamping Ejection
Uses the 879.6 N push force at 0.7 MPa to eject dense metal parts from a press bed, relying on the adjustable air cushion to soften the 220 mm stroke termination.
Pallet Diverting
Pushes loaded pallets sideways off a high-speed belt, where the needle-set cushion absorbs the sudden stop and the SUS304 barrel withstands industrial dust.
Vertical Material Lift
Raises components weighing up to 32 kg in a 2:1 safety margin rig, using the CA pivot mount to accommodate slight angular misalignment during the lift.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X220SCA the Right Cylinder?
When sizing this 40 mm bore unit, 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 loads exceeding this cylinder's 879.6 N capacity at 0.7 MPa. The variable air cushion is essential when cycling heavy payloads at high speeds up to 800 mm/s, letting you fine-tune the deceleration to prevent end-cap damage. Keep in mind the cushion only decelerates the piston near the stroke end; it does not function as a lock or brake. If your system loses air, the piston will drift, so you must add an external rod lock or pilot-operated check valve to hold a suspended load safely.
This specific configuration includes a CA rear pivot cover for articulated mounting and an -S piston magnet for direct switch mounting. The 1/4" air port matches the 16 mm rod diameter to ensure adequate flow for the 220 mm stroke.
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 MFC40X220SCA FAQ
This 40 mm bore cylinder features a 1/4" air port and an M14x1.5 male rod thread. It generates a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa. At 0.7 MPa, the push force is 879.6 N and the pull force is 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
No, the variable air cushion only decelerates the piston near the end of the stroke and does not act as a lock or brake. If air pressure is lost or the valve is centered, the piston will drift. To hold a suspended load safely, you must install an external rod lock or a pilot-operated check valve.
