Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X40CA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X40CA 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 MFC20X40CA
Dial in end-of-stroke deceleration with the AirTAC MFC20X40CA, a JIS-standard round-body mini cylinder built for double-acting service. A variable air cushion at both ends lets you turn a needle to soak up high-speed shock, protecting the load and cutting noise versus a simple bumper. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown, while the CA rear pivot cover simplifies direct rear mounting.
At 20 mm bore and 40 mm stroke, this unit generates 157 N of push force at 0.5 MPa (131.9 N pull) and uses a 1/8" port. For the same bore and stroke the MFC body is shorter than an ISO 6432 cylinder, saving valuable machine length. This non-magnet SKU cannot take a sensor; add the -S variant to enable CMSG, DMSG or EMSG switches.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X40CA Is Used
Light-Part Ejection
Pushes small moulded components out of a fixture at speed, using the adjustable air cushion to prevent the 8 kg payload from slamming at the end of the 40 mm stroke.
Package Diverting
Actuates a lightweight routing gate on a packaging line; the needle-set deceleration absorbs shock so the 94 N working load stops smoothly without bouncing goods.
Compact Clamping
Clamps thin workpieces in a tight machining cell where the shorter-than-ISO-6432 body length saves critical space and the SUS304 barrel handles coolant spray.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X40CA the Right Cylinder?
This 20 mm bore provides a safe working load of about 94 N (roughly 60 percent of the 157 N push force at 0.5 MPa), lifting around 8 kg vertically with a 2:1 margin. If your payload drops below that, no smaller MFC bore exists. If you need more thrust, step up to the MFC25, which delivers 245.3 N at 0.5 MPa. The variable air cushion matters most when driving heavier masses at high speed, but remember it only decelerates near stroke end—it is not a brake. The piston will drift on air loss, so fit an external rod lock or pilot check valve if you must hold a load.
Because this specific SKU lacks the -S magnet, it cannot accept position switches. Match your mounting needs using LB foot, FA flange, SDB pivot or TC trunnion brackets on the front cover, and use the built-in CA rear pivot for direct clevis mounting.
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 MFC20X40CA FAQ
This 20 mm bore cylinder uses a 1/8" port and an 8 mm rod with an M8x1.25 male 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.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG or EMSG switches. You must order the -S variant to enable sensing. The variable air cushion at both ends only decelerates the piston near stroke end and does not lock or hold the load.
