Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X90SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X90SCA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 90mm 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 MFC40X90SCA
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 riveted aluminium covers and SUS304 stainless steel barrel 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. The built-in piston magnet (-S) enables direct mounting of CMSG, DMSG, or EMSG switches for position sensing.
A defining feature is the variable air cushion at both ends, allowing you to turn a needle to soak up high-speed end-of-stroke shock, protecting the load and cutting noise. Operating at speeds of 30-800 mm/s, it provides a safe working load of roughly 377 N (about 60% of the 0.5 MPa push force). With a 2:1 safety margin, it lifts about 32 kg vertically. The rear CA pivot cover simplifies angular mounting, while the 1/4" port handles the required air volume.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X90SCA Is Used
Heavy Package Diversion
Uses the 879.6 N push force at 0.7 MPa to deflect heavy cartons on a high-speed sorter, relying on the adjustable air cushion to silently stop the 90 mm stroke.
Press Ejection
Pushes finished metal parts out of a press bed, where the SUS304 stainless barrel withstands minor coolant splash and the CA pivot absorbs side loads.
Pallet Stopper Gate
Acts as a robust stop gate for loaded pallets, lifting roughly 32 kg vertically with a 2:1 margin while the rear CA pivot accommodates frame alignment.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X90SCA the Right Cylinder?
When sizing this 40 mm bore, evaluate both directions: if your payload is lighter, the MFC32 bore provides 402.2 N of push force at 0.5 MPa, but this MFC40 is the largest available option in the series, delivering a maximum theoretical force of 128.1 kgf at 1.0 MPa. The variable air cushion is essential when cycling heavy loads at high speeds, as it decelerates the piston smoothly near the stroke end. Note that the cushion only decelerates; it does not act as a lock. If the application requires the load to be held in place upon air loss or when a valve is centered, you must integrate an external rod lock or a pilot-operated check valve, as the piston will drift otherwise. The -S magnet pairs with CMSG/DMSG/EMSG sensors, and the CA back cover supports pivot mounting.
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 MFC40X90SCA FAQ
This 40 mm bore cylinder features a 1/4" air port and a 16 mm piston 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, the variable air cushion only decelerates the piston near the stroke end to reduce shock; it is not a brake or lock. If air loss occurs or the valve is centered, the piston will drift. To maintain a vertical position, you must install an external rod lock or a pilot-operated check valve.
