Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X25SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X25SCA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 25mm 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 MFC40X25SCA
Delivering 628.3 N of push force at 0.5 MPa, this 40 mm bore, 25 mm stroke actuator is a JIS-standard round-body mini cylinder built for rapid cycling. An adjustable needle valve at both ends provides a variable air cushion, letting you dial in the deceleration to soak up end-of-stroke shock at high speeds. The riveted aluminium covers and SUS304 stainless barrel resist mild corrosion and washdown, while the integrated CA rear pivot simplifies rear-clevis mounting. Because the -S suffix denotes a built-in piston magnet, this unit is fully ready for CMSG, DMSG, or EMSG position switches.
For the same bore and stroke, the MFC body is notably shorter than an ISO 6432 cylinder, saving valuable mounting length without sacrificing power. Operating at speeds from 30 to 800 mm/s, it handles a safe working load of roughly 377 N (about 60% of the 0.5 MPa push force) and lifts approximately 32 kg vertically with a 2:1 safety margin. The 1/4" port and M14x1.5 male rod thread ensure robust pneumatic and mechanical connections for heavy-duty tasks.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X25SCA Is Used
Heavy Clamping Stations
Uses the full 628.3 N push force to secure heavy metal components during machining, relying on the variable cushion to prevent recoil when reaching the 25 mm stroke end.
High-Speed Diverters
Rapidly sorts heavy packages along a line at up to 800 mm/s, with the adjustable needle valve absorbing the kinetic energy of sudden stops to protect the payload.
Vertical Lift Gates
Raises access gates weighing up to 32 kg, taking advantage of the CA pivot mount for smooth articulation and the SUS304 barrel for humid environments.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X25SCA the Right Cylinder?
When sizing this 40 mm bore actuator, look down to the MFC32 if your load is lighter—it generates 402.2 N of push force at 0.5 MPa and might better suit mid-range tasks. However, if you need the maximum 879.6 N push at 0.7 MPa or the theoretical 128.1 kgf ceiling, this MFC40 is the largest available option in the series. The variable air cushion is essential when moving heavy loads at high velocities, as it prevents harsh end-of-stroke impacts that a fixed bumper cannot adequately absorb.
Remember that the air cushion only decelerates the piston near the stroke end; it does not function as a lock or brake. If your application must hold a vertical load during air loss or valve centering, the piston will drift, so you must add an external rod lock or a pilot-operated check valve. This specific SKU includes the -S magnet for sensors and features a CA back cover, so pair it with CMSG/DMSG/EMSG switches and appropriate rear pivot hardware.
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 MFC40X25SCA 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 of push force and 527.8 N of pull force. At 0.7 MPa, the push increases to 879.6 N and the pull to 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 acts purely as a shock absorber, never as a lock or brake. If air loss occurs, the piston will drift. To maintain a vertical position, you must install an external rod lock or a pilot-operated check valve.
