Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X900SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X900SCA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 900mm 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 MFC40X900SCA
Delivering 628.3 N of push force at 0.5 MPa, this double-acting stainless mini cylinder tackles heavy loads with ease. The MFC40X900SCA features a JIS-standard round-body construction with a SUS304 barrel and riveted aluminium covers, offering excellent resistance to mild corrosion and washdown environments. Because the stroke is 900 mm, it is a non-standard, made-to-order variant exceeding the 500 mm standard maximum.
A defining trait of the MFC series is the variable air cushion at both ends, which uses a needle valve to absorb end-of-stroke shock at high speeds, protecting your payload. For the same bore and stroke, the MFC body is shorter than an ISO 6432 cylinder, saving valuable mounting length. With a safe working load of about 377 N, it can vertically lift approximately 32 kg with a 2:1 safety margin. The 1/4" port and M14x1.5 male rod thread handle the necessary airflow, while the included -S magnet enables CMSG, DMSG, or EMSG sensors.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X900SCA Is Used
Long-Stroke Diverting
Ideal for pushing heavy pallets across a wide conveyor belt using its 900 mm reach and 628.3 N push force.
Vertical Lowering
Safely lowers 30 kg fixtures with the adjustable air cushion decelerating the load smoothly at the bottom.
High-Bay Extraction
Extracts totes from deep shelving units where the shorter JIS body length saves critical machine space.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X900SCA the Right Cylinder?
When sizing this 40 mm bore, evaluate your force needs carefully. If 628.3 N at 0.5 MPa is excessive, stepping down to the MFC32 provides 402.2 N; since 40 mm is the largest available bore in this series, moving up is not an option. The variable air cushion is essential for high-speed or heavy-load applications to prevent harsh impacts. Keep in mind the cushion only decelerates the piston near the stroke end and does not function as a lock or brake. If your application must hold a load vertically during air loss, install an external rod lock or pilot-operated check valve. The CA back cover provides a rear pivot mount, and the -S magnet allows for precise position sensing.
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 MFC40X900SCA FAQ
This 40 mm bore cylinder features a 1/4" port and an M14x1.5 male rod 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 end of the stroke to reduce shock; it is not a brake or lock. The piston will drift if air is lost. You must use an external rod lock or pilot check valve for load holding.
