Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X280SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X280SCM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 280mm 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 MFC20X280SCM
Dialing in end-of-stroke deceleration is effortless with the needle-set variable air cushion on this 20 mm bore actuator. As a JIS-standard round-body mini cylinder, it features a SUS304 stainless barrel and riveted aluminium covers that shrug off 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 without sacrificing the 280 mm travel.
Operating at 30-800 mm/s, the double-acting piston generates 157 N of push force at 0.5 MPa. This translates to a safe working load of roughly 94 N, or the ability to lift about 8 kg vertically with a 2:1 safety margin. The -S suffix equips the piston with a built-in magnet for CMSG, DMSG or EMSG position switches, while the CM round-end back cover completes the rear assembly. Air connects via a 1/8" port.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X280SCM Is Used
Package Diverting
Routes light parcels at high speed on a 280 mm stroke, relying on the variable air cushion to prevent harsh slams when shifting boxes between sorting lanes.
Small Component Ejection
Pushes machined micro-parts out of a fixture with 94 N of safe working force, using the adjustable needle to gentle the ejection impact and protect surface finishes.
Vertical Tray Lifting
Elevates lightweight component trays weighing up to 8 kg, using the built-in -S magnet to confirm lift completion via CMSG or DMSG reed sensors.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X280SCM the Right Cylinder?
If 157 N of push at 0.5 MPa leaves you underpowered, stepping up to the MFC25 bore yields 245.3 N; conversely, the 20 mm bore is the smallest available in the MFC family. The variable air cushion at both ends is essential when cycling heavy loads or operating near the 800 mm/s upper speed limit, as it absorbs shock that a fixed bumper cannot. Remember that the cushion only decelerates the piston near the stroke end—it is not a brake. If your application must hold a vertical load during air loss or valve centering, the piston will drift, requiring an external rod lock or pilot-operated check valve. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion brackets.
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 MFC20X280SCM FAQ
This 20 mm bore cylinder has a 1/8" air port and an M8x1.25 male rod thread. At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it provides 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa.
No, the variable air cushion only decelerates the piston near the end of the stroke and does not function as a lock or brake. If air pressure is lost, the piston will drift. To suspend a load safely, you must install an external rod lock or a pilot-operated check valve.
