Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X350SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X350SCM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 350mm 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 MFC20X350SCM
Saving mounting length is a hallmark of this JIS-standard round-body mini cylinder, which is shorter than an ISO 6432 unit for the same 20mm bore and 350mm stroke. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion, while the built-in magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing.
A variable air cushion at both ends lets you dial in the needle to soak up high-speed end-of-stroke shock, protecting the load and cutting noise. Operating at 30-800 mm/s, it yields a 157 N push force at 0.5 MPa, making the safe working load roughly 94 N or about 8 kg of vertical lift with a 2:1 margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X350SCM Is Used
Package Diverting
Shifts lightweight cartons at high speed across a 350mm stroke, relying on the variable air cushion to prevent harsh end impacts.
Small Part Ejection
Pushes machined components out of a fixture using 157 N of push force at 0.5 MPa without slamming the ejection arm.
Vertical Lift Gates
Raises access flaps with a safe working load of roughly 94 N, using the -S magnet to confirm gate position.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X350SCM the Right Cylinder?
For lighter tasks, the MFC20 at 157 N push (0.5 MPa) handles moderate loads; if you need more muscle, step up to the MFC25 which provides 245.3 N. The adjustable cushion is essential when moving loads at high speed over the 350mm travel, as it decelerates the piston smoothly. This CM round-end rear cover model uses a 1/8" port and an M8x1.25 male rod thread.
Because the air cushion only decelerates near the stroke end, it does not function as a lock or brake. If your application must hold a load vertically during air loss, add an external rod lock or pilot-operated check valve.
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 MFC20X350SCM FAQ
This 20mm bore cylinder has 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.
No, the variable air cushion only decelerates the piston near the stroke end and is not a brake. The piston will drift on air loss, so you should use an external rod lock or pilot check valve for vertical load holding.
