Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X125SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X125SCA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 125mm 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 MFC20X125SCA
Delivering 157 N of push force at 0.5 MPa, this 20 mm bore double-acting cylinder uses a needle-set variable air cushion at both ends to soak up high-speed end-of-stroke shock. The riveted aluminium covers and SUS304 stainless barrel resist mild corrosion and washdown, while the built-in piston magnet (-S) supports CMSG, DMSG and EMSG sensors. Featuring a 125 mm stroke, 1/8" port and M8x1.25 male rod thread, it is a JIS-standard round-body mini.
For the same bore and stroke, the MFC body is notably shorter than an ISO 6432 cylinder, saving valuable mounting length. It yields a safe working load of roughly 94 N and lifts about 8 kg vertically with a 2:1 margin. The rear CA pivot cover simplifies angular mounting, and the cushion strictly decelerates the load near stroke end without acting as a lock.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X125SCA Is Used
Light-Part Ejection
Cushions the end-of-stroke impact when rapidly pushing 8 kg moulded parts out of a machining fixture at high cycle rates.
Package Diverting
Uses the CA pivot mount to swing a lightweight routing gate on a packaging line, absorbing shock during fast 125 mm strokes.
Lab Test Positioning
Drives a sample tray in a washdown environment, relying on the SUS304 barrel and needle-tuned deceleration for smooth stops.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X125SCA the Right Cylinder?
If 157 N at 0.5 MPa is insufficient, step up to the MFC25 bore, which provides 245.3 N of push force; no smaller MFC bore exists. The variable air cushion is essential when cycling at high speeds or moving sensitive loads, as it replaces fixed bumpers with adjustable deceleration. Because a standard cylinder drifts when air pressure drops, install an external rod lock or pilot-operated check valve if you need to hold a suspended load. The -S magnet enables position sensing, and you can pair the CA rear pivot with LB foot, FA flange or TC trunnion mounts.
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 MFC20X125SCA FAQ
This 20 mm bore cylinder features a 1/8" port and an M8x1.25 male rod thread. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa.
The -S suffix indicates a built-in piston magnet for CMSG, DMSG or EMSG sensors. The variable air cushion only decelerates the piston near stroke end; it is not a brake. The cylinder will drift on air loss, so use an external rod lock or pilot check valve for vertical load holding.
