Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X72SU
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X72SU is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 72mm 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 MFC20X72SU
Delivering 157 N of push force at 0.5 MPa, this double-acting 20 mm bore mini cylinder relies on a needle-set variable air cushion at both ends to soak up high-speed end-of-stroke shock. The riveted SUS304 stainless barrel and aluminium covers resist mild corrosion and washdown, while the U flat-end rear cover keeps the overall footprint tight. A built-in piston magnet (-S) enables direct mounting of CMSG, DMSG or EMSG switches.
For the same 20 mm bore and 72 mm stroke, the JIS-standard round-body design is physically shorter than an ISO 6432 cylinder, saving valuable mounting length. Operating at speeds of 30-800 mm/s via a 1/8" port, it provides a safe working load of roughly 94 N and lifts about 8 kg vertically with a 2:1 margin. The front cover carries a fixed anti-impact pad and the piston uses a two-way oil-retaining seal for smooth motion.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X72SU Is Used
Light Part Ejection
Uses the 157 N push force to eject small moulded parts rapidly, relying on the variable air cushion to prevent harsh end-of-stroke impacts.
Package Diverting
Pushes light cartons on a belt line; the needle-set cushion allows fast 30-800 mm/s cycling without jolting the mechanism.
Lab Sample Handling
Moves delicate test tubes safely, where the SUS304 stainless barrel offers mild corrosion resistance and the cushion protects the glass.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X72SU the Right Cylinder?
If 157 N of push at 0.5 MPa is insufficient, step up to the MFC25, which provides 245.3 N; there is no smaller MFC bore, so this 20 mm version is the most compact option available. Choose this model when cycling at high speeds or moving sensitive loads where the adjustable air cushion is required to decelerate the piston smoothly.
Remember that the air cushion only reduces end-of-stroke impact and does not function as a brake; if air pressure drops, the piston will drift, so fit an external rod lock or pilot-operated check valve for suspended loads. This -S variant includes the magnet needed for CMSG, DMSG or EMSG sensors, and the U back cover suits flat mounting surfaces.
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 MFC20X72SU FAQ
It has a 1/8" port and generates 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 stroke end and is not a brake. The piston will drift on air loss, so an external rod lock or pilot check valve is required for holding suspended loads.
