Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X80SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X80SCA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 80mm 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 MFC40X80SCA
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder tackles heavy loads with precision. The riveted aluminium covers and SUS304 stainless 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.
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 versus a bumper mini. The integrated -S magnet enables CMSG, DMSG, or EMSG switches for position sensing. With a 1/4" port and M14x1.5 male rod thread, it provides 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 MFC40X80SCA Is Used
Heavy Package Diversion
Pushes dense 30 kg cartons off a high-speed sorting line, using the variable air cushion to halt the 80 mm stroke softly without jarring the products.
Press Ejection
Ejects formed metal components from a press, absorbing the rapid end-of-stroke impact to protect tooling and reduce workshop noise.
Pallet Stopper
Acts as a robust stop for loaded pallets, leveraging the 628.3 N push force and washdown-resistant SUS304 barrel to handle repeated impacts safely.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X80SCA the Right Cylinder?
When sizing this 40 mm bore model, stepping down to the MFC32 provides 402.2 N of push force at 0.5 MPa, which may suit lighter loads. As 40 mm is the largest available MFC bore, exceeding this capacity requires a different cylinder family. The variable air cushion is essential when cycling at high speeds or moving heavy masses, as it decelerates the piston smoothly near stroke end.
Because a standard cylinder does not hold its load on air loss or when a valve is centered, the piston will drift; for a held load, install an external rod lock or a pilot-operated check valve. This unit includes a CA rear pivot cover, and its built-in -S magnet supports CMSG, DMSG, or EMSG electronic or reed switches for precise end-position feedback.
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 MFC40X80SCA FAQ
This 40 mm bore cylinder features a 1/4" port and an M14x1.5 male rod thread. At 0.5 MPa it provides 628.3 N push and 527.8 N pull force. At 0.7 MPa it delivers 879.6 N push and 738.9 N pull. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
It uses a variable air cushion at both ends, set via a needle valve, to decelerate the piston near stroke end and reduce shock; it is not a lock or brake. If you need to hold a load vertically on air loss, you must add an external rod lock or pilot check valve. The -S magnet allows CMSG, DMSG, or EMSG switches for position detection.
