Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X30SU
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X30SU is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 30mm 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 MFC20X30SU
Dial in end-of-stroke deceleration with the AirTAC MFC20X30SU, a JIS-standard round-body mini cylinder built for high-speed actuation. The variable air cushion at both ends uses a needle valve to absorb shock, protecting your payload far better than a fixed bumper. Its SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown environments.
Generating 157 N of push force at 0.5 MPa, this double-acting 20 mm bore unit provides a safe working load of roughly 94 N and lifts about 8 kg vertically with a 2:1 margin. The U flat-end back cover simplifies direct mounting, and the built-in -S magnet supports CMSG, DMSG, and EMSG position switches. Featuring a 1/8" port and an M8x1.25 male rod thread, the overall body is notably shorter than an ISO 6432 cylinder of the same bore and stroke.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X30SU Is Used
Light-Part Ejection
Uses the 94 N safe working load to push small plastic components out of a mould, relying on the needle-set cushion to prevent impact bounce at 800 mm/s.
Package Sorting Diverter
Rapidly deflects lightweight cardboard cartons on a line, where the adjustable air cushion silently absorbs the 30 mm stroke shock.
Lab Automation Stopper
Acts as a precise end-stop for sliding test tubes, using the U flat-end cover for flush mounting and the SUS304 barrel for chemical resistance.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X30SU the Right Cylinder?
For lighter payloads, this 20 mm bore provides 131.9 N pull at 0.5 MPa; if your application requires more thrust, stepping up to the MFC25 yields 245.3 N. The adjustable cushion is essential when cycling at high speeds or moving sensitive masses, as it only decelerates the piston near the stroke end and does not function as a lock. Remember that a standard cylinder drifts when air pressure drops, so install an external rod lock or pilot check valve if you need to hold a suspended load. Mounting options include LB foot, FA flange, 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 MFC20X30SU FAQ
This 20 mm bore double-acting cylinder features a 1/8" port and an M8x1.25 male rod 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 of 32 kgf at 1.0 MPa.
Yes, the -S suffix means it has a built-in piston magnet for CMSG, DMSG, or EMSG switches. However, the variable air cushion only decelerates the piston near stroke end; it is not a brake. The cylinder will drift on air loss, so use an external rod lock or pilot check valve for vertical holding.
