Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X225SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X225SCA 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 MFC40X225SCA
Delivering 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore mini cylinder relies on a needle-set variable air cushion at both ends to soak up high-speed end-of-stroke shock. The riveted aluminium covers and SUS304 stainless barrel resist mild corrosion and washdown, while the built-in CA pivot back cover simplifies rear articulation. A 1/4" port and M14x1.5 male rod thread handle the required airflow and mounting.
For the same bore and stroke, the JIS-standard round-body housing is noticeably shorter than an ISO 6432 cylinder, saving valuable machine space. The -S suffix equips the piston with a magnet for CMSG, DMSG or EMSG switches. In practical terms, it provides a safe working load of roughly 377 N, lifting about 32 kg vertically with a 2:1 safety margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X225SCA Is Used
High-Speed Pallet Diverting
Shifts heavy pallets laterally using the full 628.3 N thrust, relying on the adjustable air cushion to prevent jarring stops during rapid 225 mm strokes.
Carton Flap Folding
Folds thick cardboard flaps on automated lines where the SUS304 barrel withstands dust and washdown, while the CA pivot accommodates angular misalignment.
Vertical Material Lift
Raises 32 kg components vertically through 225 mm, using the needle-set cushion to bring the load to a gentle halt at the bottom of the stroke.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X225SCA the Right Cylinder?
If 628.3 N at 0.5 MPa is excessive, step down to the MFC32 which provides 402.2 N; as 40 mm is the largest available bore in this series, moving up requires a different platform. The variable air cushion is essential when driving heavy 32 kg loads at high speeds, as it decelerates the piston smoothly without harsh impacts.
Because the cushion only slows the rod near stroke end and provides no braking force mid-stroke, the piston will drift if air pressure drops. Use an external rod lock or pilot-operated check valve to secure a suspended load. Mounting is straightforward via the rear CA pivot, and position sensing requires the included -S magnet.
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 MFC40X225SCA FAQ
This 40 mm bore cylinder features a 1/4" port and generates 628.3 N push / 527.8 N pull at 0.5 MPa, and 879.6 N push / 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 and acts as neither a brake nor a lock; the rod will drift on air loss. The -S suffix denotes a built-in magnet for CMSG, DMSG or EMSG sensors.
