Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X450SU
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X450SU is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 450mm 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 MFC20X450SU
Taming end-of-stroke shock in tight assemblies, the AirTAC MFC20X450SU relies on a needle-set variable air cushion at both ends to decelerate high-speed moves. This JIS-standard round-body mini cylinder pairs a SUS304 stainless steel barrel with riveted aluminium covers to resist mild corrosion and washdown. Because the body is shorter than an ISO 6432 cylinder for the same 20 mm bore and 450 mm stroke, it saves valuable mounting length.
Generating 157 N of push force at 0.5 MPa (131.9 N pull), it yields a safe working load of about 94 N, or roughly 8 kg of vertical lift with a 2:1 margin. The included -S magnet supports CMSG, DMSG and EMSG switches for position sensing. A U flat-end back cover eases flush mounting, and the 1/8" port keeps airflow compact for the 8 mm rod.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X450SU Is Used
Light-Part Ejection
Uses the 94 N safe working load to push small plastic parts out of a mould at high speed, with the variable air cushion preventing end-of-stroke bounce.
Package Diverting
Swings a lightweight guide flap across a belt line; the SUS304 barrel withstands humid packing environments while the U flat-end rear mounts flush to the frame.
Small Tray Indexing
Shifts an 8 kg tray stack vertically using the 2:1 lift margin, relying on the needle-set cushion to soften the 450 mm stroke arrival.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X450SU the Right Cylinder?
If 157 N at 0.5 MPa is insufficient, step up to the MFC25, which provides 245.3 N of push force; since 20 mm is the smallest bore in the range, there is no smaller MFC to drop down to. Choose this model when you need to move a load at speed and want to eliminate the bang of a fixed bumper. The cushion needle only decelerates the piston near stroke end, so for holding a load on air loss fit an external rod lock or pilot check valve. Mount via LB foot, FA flange, SDB pivot or TC trunnion, and wire your sensor to the -S magnet.
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 MFC20X450SU FAQ
At 0.5 MPa it delivers 157 N push and 131.9 N pull. At 0.7 MPa it delivers 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa. This 20 mm bore cylinder uses a 1/8" port and an 8 mm rod.
No. The variable air cushion only decelerates the piston near the end of the stroke; it is not a brake or lock. If air is lost, the piston will drift. For vertical load holding you must add an external rod lock or pilot-operated check valve. The -S magnet allows CMSG, DMSG or EMSG sensors to confirm position.
