Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X225SU
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X225SU 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 MFC20X225SU
Featuring an adjustable needle-set air cushion at both ends, the AirTAC MFC20X225SU mini cylinder eliminates end-of-stroke shock during high-speed travel. This JIS-standard round-body actuator pairs an SUS304 stainless steel barrel with riveted aluminium covers to handle mild washdowns, and its U-type flat-end rear cover simplifies direct mounting. For the same 20 mm bore and 225 mm stroke, the body is noticeably shorter than an ISO 6432 cylinder, saving valuable machine space.
Delivering 157 N of push force and 131.9 N of pull force at 0.5 MPa, this double-acting unit is built for brisk 30-800 mm/s cycling. The 1/8" port feeds the 8 mm piston rod, and the integrated -S magnet enables CMSG, DMSG or EMSG position sensing. Based on the 0.5 MPa thrust, it provides a safe working load of roughly 94 N and lifts about 8 kg vertically with a 2:1 margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X225SU Is Used
Light-Part Ejection
Shoots small plastic or metal parts out of a machining zone at speed, using the variable air cushion to stop the 225 mm travel softly without bouncing the component.
Package Sorting Diverter
Pushes lightweight cartons off a main conveyor belt, providing just enough 157 N push force to redirect items while the cushion absorbs the high-frequency impact.
Vertical Tray Lifter
Lifts stacked trays weighing up to 8 kg using a 2:1 safety margin, relying on the flat-end U cover for stable base mounting and the -S magnet for height confirmation.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X225SU the Right Cylinder?
When sizing this 20 mm bore actuator, step down if speeds are low and space is tight, or step up to the MFC25 which provides 245.3 N of push force at 0.5 MPa if your payload exceeds the 94 N safe working load. The variable air cushion is essential for heavy loads or fast 225 mm strokes, as it decelerates the piston smoothly instead of slamming it. Because a standard cylinder drifts when air pressure drops, use an external rod lock or pilot check valve if you need to hold a vertical load securely.
The U-type flat-end back cover suits direct rear mounting, while options like LB foot or FA flange brackets adapt it to various frames. Since this SKU includes the -S magnet, you can directly mount CMSG, DMSG or EMSG sensors for end-position confirmation.
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 MFC20X225SU FAQ
This 20 mm bore cylinder has a 1/8" port and an 8 mm rod. 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 of 32 kgf at 1.0 MPa.
No, the variable air cushion only decelerates the piston near the stroke end to reduce shock; it is not a brake or lock. For position sensing, the built-in -S magnet allows you to mount CMSG, DMSG or EMSG switches directly onto the SUS304 stainless steel barrel.
