Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X320SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X320SCA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 320mm 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 MFC20X320SCA
Delivering 157 N of push force at 0.5 MPa, the AirTAC MFC20X320SCA is a JIS-standard round-body mini cylinder built for double-acting operation. Tuning the variable air cushion at both ends lets you dial in the needle to absorb high-speed end-of-stroke shock, protecting your payload while cutting noise. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown environments.
This 20 mm bore, 320 mm stroke model features a 1/8" port and a CA rear pivot cover. Because the -S suffix equips the piston with a magnet, you can mount CMSG, DMSG, or EMSG sensors for position detection. For the same bore and stroke, this riveted body is physically shorter than an ISO 6432 cylinder, saving valuable mounting length without sacrificing the 8 mm rod and M8x1.25 male thread.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X320SCA Is Used
Package Diverting
Pushes light cartons at high speed onto secondary lines where the variable air cushion prevents harsh slams that could scuff packaging.
Small Part Ejection
Ejects machined components from a fixture using 157 N of push force, relying on the cushion needle to soften the end stop and protect delicate parts.
Bin Sorting
Handles lightweight product sorting into bins with the CA pivot mount allowing easy angular alignment, while sensors confirm the 320 mm stroke position.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X320SCA the Right Cylinder?
If 157 N of push at 0.5 MPa leaves you underpowered, step up to the MFC25 which provides 245.3 N; there is no smaller MFC bore, so for lighter jobs you would need a different series. The adjustable air cushion is essential when driving heavier masses at high speeds, as it decelerates the piston smoothly near the ends. Note that this cushion only slows the stroke and does not act as a brake—the piston will drift if air pressure drops, so fit an external rod lock or pilot check valve for suspended loads.
Mounting flexibility comes from the CA rear pivot, while the internal magnet enabled by the -S option supports direct sensor switching. Keep operating pressure between 0.15 and 1.0 MPa, and expect a safe working load around 94 N, which means it lifts about 8 kg vertically with a 2:1 safety margin.
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 MFC20X320SCA 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 force of 32 kgf at 1.0 MPa.
The -S suffix means the piston has a built-in magnet for CMSG, DMSG, or EMSG sensors. The variable air cushion only decelerates the piston near stroke end to reduce shock; it is not a brake, so the cylinder cannot hold a load vertically on air loss—install an external rod lock or pilot check valve for that.
