Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC25X50SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC25X50SCA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø25mm bore and 50mm stroke, 1/8" 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 MFC25X50SCA
Dial in end-of-stroke deceleration with the AirTAC MFC25X50SCA, a JIS-standard round-body mini cylinder built for double-acting service. A variable air cushion at both ends lets you needle-set the damping to absorb high-speed shock, protecting your payload far better than a fixed bumper. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown, while the built-in magnet (-S) enables position sensing with CMSG, DMSG or EMSG switches.
In the 25 mm bore class, this unit generates 245.3 N of push force and 206.1 N of pull force at 0.5 MPa. That translates to a safe working load of roughly 147 N, or the ability to lift about 12.5 kg vertically with a 2:1 safety margin. It features a 50 mm stroke, a 1/8" port, and a CA pivot back cover. For the same bore and stroke, the MFC body is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length without conforming to that standard.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC25X50SCA Is Used
Package Diverting
Stops and diverts light cartons at 30-800 mm/s, using the variable cushion to halt the 12.5 kg payload smoothly without slamming the end cap.
Filler Head Positioning
Moves a filling nozzle up and down 50 mm; the SUS304 barrel withstands washdown while the needle damping protects the nozzle assembly.
Small Press Ejection
Kicks lightweight moulded parts out of a die, relying on 206.1 N of pull force at 0.5 MPa to retract the rod quickly and quietly.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC25X50SCA the Right Cylinder?
If 245.3 N of push at 0.5 MPa is too much, step down to the MFC20 which provides 157 N; if you need more muscle, the MFC32 offers 402.2 N. Choose this 25 mm bore when moving moderate masses at high speeds where the adjustable needle cushion is essential to prevent end-of-stroke banging. Note that the air cushion only decelerates the piston near the end of travel—it is not a lock. Because a plain cylinder drifts when air pressure drops or the valve is centered, you must add an external rod lock or pilot-operated check valve to hold a suspended load. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion, and the CA rear cover provides a pivot point.
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 MFC25X50SCA FAQ
This 25 mm bore cylinder has a 1/8" port and a male M10x1.25 rod thread. At 0.5 MPa it pushes with 245.3 N and pulls with 206.1 N. At 0.7 MPa the push increases to 343.4 N and the pull to 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa.
No, the piston will drift. The variable air cushion only decelerates the rod near the end of its stroke to reduce shock; it is not a brake or lock. To hold a load securely, you must install an external rod lock or a pilot-operated check valve.
