Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X75CM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X75CM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 75mm 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 MFC20X75CM
Delivering 157 N of push force at 0.5 MPa, this double-acting round-body mini cylinder is built for fast, repetitive motion. The MFC20X75CM features a variable air cushion at both ends, letting you dial in a needle valve to absorb end-of-stroke shock and reduce noise at high speeds. Its SUS304 stainless barrel and riveted aluminium covers resist mild corrosion, while the CM round-end back cover suits compact installations. Furthermore, for the same bore and stroke, the JIS-standard body is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length.
This specific SKU omits the internal magnet, meaning it cannot host CMSG, DMSG, or EMSG position switches; add an -S variant if you require sensing. With a 75 mm stroke and an 8 mm rod, it provides a safe working load of roughly 94 N (about 60% of the 0.5 MPa push force) and lifts approximately 8 kg vertically with a 2:1 safety margin. The 1/8" port ensures efficient airflow across its 30-800 mm/s operating speed range.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X75CM Is Used
Light-Part Ejection
Uses the 157 N @0.5 MPa thrust to push small plastic components out of a mould, relying on the needle-set air cushion to prevent end-of-stroke slamming at high cycle rates.
Package Diverting
Employs the 75 mm stroke to deflect lightweight cartons on a sorting line, where the SUS304 stainless barrel withstands occasional washdowns.
Small-Part Pressing
Provides a safe working load of about 94 N for seating delicate electronic inserts, with the CM round-end cover fitting neatly into tight assembly fixtures.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X75CM the Right Cylinder?
When sizing this 20 mm bore actuator, step down if your payload is very light, or move up to the MFC25 (245.3 N push at 0.5 MPa) if you need substantially more thrust. The adjustable cushion shines in high-speed or heavy-load scenarios where a fixed bumper would transmit damaging impact energy. Keep in mind the cushion only decelerates the piston near the stroke end—it is not a braking device. Because a standard cylinder drifts when air pressure drops or a valve centers, you must integrate an external rod lock or pilot-operated check valve for fail-safe load holding. Finally, since this exact model lacks the -S magnet, you cannot mount magnetic sensors; choose the -S version for CMSG, DMSG, or EMSG switch compatibility.
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 MFC20X75CM FAQ
This 20 mm bore cylinder features a 1/8" port and an 8 mm rod. It generates 157 N push and 131.9 N pull at 0.5 MPa, increasing to 219.8 N push and 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
No, this specific SKU does not include an internal magnet, so it cannot support CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. Additionally, its variable air cushion only decelerates the load near the stroke end and does not function as a lock.
