Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X25SCMLB
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X25SCMLB is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 25mm 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 MFC20X25SCMLB
Delivering 157 N of push force at 0.5 MPa, this 20 mm bore double-acting mini cylinder is built for rapid actuation. The defining feature of the MFC series is the variable air cushion at both ends; by turning a needle valve you tune the deceleration to absorb high-speed end-of-stroke shock, protecting the payload and cutting noise. A built-in piston magnet (-S) enables position sensing with CMSG, DMSG or EMSG switches.
The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments. For the same 20 mm bore and 25 mm stroke, this JIS-standard round body is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length. Based on the 0.5 MPa thrust, it handles a safe working load of about 94 N and lifts roughly 8 kg vertically with a 2:1 safety margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X25SCMLB Is Used
Light-Part Ejection
Uses the 94 N safe working load to push small plastic or stamped components out of a fixture rapidly, relying on the tuned air cushion to prevent bounce-back.
Flap Deflection
Ideal for fast carton sealing where the 8 kg vertical lift margin handles light tamping arms while the needle valve damps the sudden stroke end.
Sensor Sorting
The -S magnet pairs with DMSG switches to confirm small part rejection strokes in tight machinery where the shorter-than-ISO-6432 body length is critical.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X25SCMLB the Right Cylinder?
If 157 N 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 variant is the most compact option. The adjustable air cushion is essential when cycling at high speeds or moving delicate masses, but note it only decelerates the piston near the stroke end and does not act as a brake. If you need to prevent drift on air loss, add an external rod lock or pilot check valve. This configuration includes the LB foot mounting accessory and a CM round-end rear cover for versatile installation.
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 MFC20X25SCMLB FAQ
This 20 mm bore cylinder features 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.
No, the variable air cushion only decelerates the piston near the end of the stroke to reduce shock; it is not a lock or brake. The piston will drift on air loss or when a valve is centered. To hold a load securely, you must install an external rod lock or a pilot-operated check valve.
