Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X40SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X40SCA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 40mm 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 MFC20X40SCA
Taming end-of-stroke shock in tight spaces, the AirTAC MFC20X40SCA is a JIS-standard round-body mini cylinder built for double-acting service. A variable air cushion at both ends lets you dial in the deceleration needle to soak up high-speed impact, protecting the load and cutting noise. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown, while the built-in -S magnet supports CMSG, DMSG and EMSG sensors for position detection.
In the 20 mm bore class, this actuator generates 157 N of push force at 0.5 MPa, making it a solid fit for light-duty positioning. It yields a safe working load of roughly 94 N, or about 60 percent of its 0.5 MPa push rating. For vertical mounting, it lifts approximately 8 kg with a 2:1 safety margin. The 1/8" port and CA pivot back cover streamline integration, and for the same bore and stroke, the riveted body is noticeably shorter than an ISO 6432 cylinder.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X40SCA Is Used
Light Part Ejection
Ejecting small plastic parts at high speed without slamming, using the adjustable air cushion to decelerate the 157 N push force smoothly.
Carton Flap Folding
Folding light packaging flaps where the 8 kg vertical lift capacity and compact JIS body length fit neatly into tight conveyor frames.
Small Component Pressing
Lightly seating electronic connectors, relying on the SUS304 stainless barrel for washdown resistance in cleanroom assembly lines.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X40SCA the Right Cylinder?
When sizing this 20 mm bore unit, step down if your load is extremely light, or move up to the MFC25 which provides 245.3 N of push at 0.5 MPa. The adjustable air cushion is essential if you are cycling near the 800 mm/s upper speed limit or moving a sensitive payload. Remember that the cushion only decelerates the piston near the stroke end; it does not function as a brake. If your application must hold a load vertically during air loss, add an external rod lock or pilot-operated check valve. The CA rear pivot works with the -S magnet option for seamless sensor 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 MFC20X40SCA FAQ
This 20 mm bore cylinder uses a 1/8" port and delivers 157 N push / 131.9 N pull at 0.5 MPa, and 219.8 N push / 184.7 N pull at 0.7 MPa. 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 acts purely as a shock absorber, never a lock. For vertical load holding during air loss, you must install an external rod lock or pilot check valve.
