Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X225U
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X225U is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 225mm 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 MFC20X225U
Damping high-speed impacts defines the AirTAC MFC20X225U, a JIS-standard round-body mini cylinder built with a SUS304 stainless barrel and riveted aluminium covers. A variable air cushion at both ends lets you dial in the needle valve to absorb end-of-stroke shock, protecting the load and lowering noise far better than a fixed bumper. For the same 20 mm bore and 225 mm stroke, this riveted body is notably shorter than an ISO 6432 cylinder, saving valuable machine length.
Generating 157 N of push and 131.9 N of pull at 0.5 MPa, this double-acting actuator suits compact automation nicely. The 1/8" port feeds the 8 mm rod, yielding a safe working load around 94 N, which means it lifts about 8 kg vertically with a 2:1 margin. This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG sensors. The flat-end U back cover mounts flush against the machine frame.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X225U Is Used
Light Part Diverting
Pushes small cardboard cartons on a packaging line at speed, using the adjustable air cushion to stop the 225 mm stroke smoothly without jarring the products.
Compact Assembly Eject
Ejects lightweight plastic moulded parts from a tight fixture, fitting into a short machine envelope thanks to the space-saving U back cover and shorter-than-ISO body.
Vertical Lift Gate
Raises an 8 kg access flap on an automated test bench, relying on the 157 N push force at 0.5 MPa to move the load reliably through the 225 mm travel.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X225U the Right Cylinder?
When sizing this 20 mm bore, step down if your load is very light, but if you need more force the next size up is the MFC25, delivering 245.3 N of push at 0.5 MPa. The adjustable cushion is essential when cycling at high speeds or moving heavier masses, as it prevents harsh end-of-stroke banging. Note that the air cushion only decelerates the piston near the stroke ends; it does not function as a brake. If your application must hold a load vertically during an air loss event, the piston will drift, so you must fit an external rod lock or a pilot-operated check valve. Because this base model has no -S magnet, position sensing is impossible here; add the -S option if you need to mount switches.
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 MFC20X225U FAQ
This 20 mm bore cylinder features a 1/8" port and an 8 mm rod. It generates 157 N push and 131.9 N pull at 0.5 MPa, or 219.8 N push and 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
No, this specific SKU lacks the internal magnet, so it cannot accept CMSG, DMSG or EMSG switches; you need the -S variant for sensing. The variable air cushion at both ends only decelerates the piston near stroke end to reduce shock, but it is not a lock or brake, so the piston will drift if air pressure is lost.
