Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X65SU
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X65SU is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 65mm 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 MFC20X65SU
Designed for high-speed actuation where end-of-stroke shock must be tamed, this 20 mm bore mini cylinder relies on a needle-set variable air cushion at both ends to decelerate the load smoothly. The riveted aluminium covers and SUS304 stainless barrel form a JIS-standard round body that is physically shorter than an ISO 6432 cylinder of the same bore and stroke, saving valuable mounting length. A built-in piston magnet (-S) enables direct mounting of CMSG, DMSG or EMSG switches.
Operating at 30-800 mm/s, the double-acting piston generates 157 N of push force at 0.5 MPa, yielding a safe working load of roughly 94 N or a vertical lift capacity of about 8 kg with a 2:1 margin. The U flat-end back cover provides a flush rear mounting face. Pneumatic connections use a 1/8" port, and the male M8x1.25 rod thread simplifies load attachment.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X65SU Is Used
Light Parts Ejection
Shoots small plastic or metal parts out of a press at speed; the adjustable air cushion prevents the 8 mm rod from slamming the end cap, protecting both the tooling and the ejected component.
Package Sorting Diverter
Pushes lightweight cartons on a conveyor at high cycle rates; the U flat-end cover allows flush rear mounting against the machine frame while the 1/8" port ensures rapid actuation.
Small Component Clamping
Holds delicate electronic housings during an assembly process; the 94 N safe working load is sufficient for secure clamping without crushing the part.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X65SU the Right Cylinder?
If 157 N of push at 0.5 MPa leaves you underpowered, step up to the MFC25 which provides 245.3 N; conversely, the 20 mm bore is the smallest available in this series. The variable air cushion is essential when cycling at high speeds or moving sensitive masses, as it absorbs impact energy that a fixed bumper cannot. Remember that the cushion only decelerates the piston near the stroke end—it does not function as a brake. If your application must hold a load vertically during air loss or valve centering, install an external rod lock or pilot-operated check valve. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion brackets.
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 MFC20X65SU FAQ
This double-acting cylinder has a 20 mm bore and uses a 1/8" air port. At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it provides 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa.
No, the piston will drift if air is lost. The needle-set variable air cushion at both ends only decelerates the piston near the end of the stroke to reduce shock; it is not a locking mechanism. For vertical load holding, you must use an external rod lock or pilot check valve. The -S magnet allows use of CMSG, DMSG or EMSG sensors.
