Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X30SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X30SCA 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 MFC20X30SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting 20 mm bore mini cylinder relies on a needle-set variable air cushion at both ends to soak up high-speed end-of-stroke shock. The riveted SUS304 stainless barrel and aluminium covers resist mild corrosion and washdown environments. Because the -S suffix equips the piston with a built-in magnet, the cylinder is ready for CMSG, DMSG or EMSG position switches.
For the same 20 mm bore and 30 mm stroke, this JIS-standard round-body design is physically shorter than a comparable ISO 6432 cylinder, saving valuable mounting length. It breathes through a 1/8" port and features a CA rear pivot cover. Based on the 0.5 MPa thrust, it handles a safe working load of roughly 94 N, lifting about 8 kg vertically with a 2:1 safety margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X30SCA Is Used
Light-Part Ejection
Uses the 157 N push stroke to flick small plastic components out of a mould, relying on the adjustable air cushion to prevent bounce at rapid cycle rates.
Package Sorting Diverter
Swings via the CA pivot to deflect lightweight cartons on a belt line, absorbing the shock of repeated high-speed actuation without slamming.
Small Assembly Press
Presses sub-miniature connectors into PCBs with a safe 94 N working load, using the needle valve to guarantee a soft, damage-free landing.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X30SCA the Right Cylinder?
When sizing this actuator, step down if your payload is very light, or move up to the MFC25 which provides 245.3 N of push force at 0.5 MPa if you need more thrust. The variable air cushion is essential when cycling at high speeds or moving heavy loads, as it decelerates the piston smoothly to protect the workpiece. Note that the cushion only eases the final impact; it does not function as a lock or brake. If the air supply drops or the valve is centred, the piston will drift, so fit an external rod lock or pilot-operated check valve for suspended loads. Mounting is straightforward using the CA back cover pivot, and the included -S magnet allows direct sensing.
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 MFC20X30SCA FAQ
This 20 mm bore cylinder uses a 1/8" port. It generates 157 N push and 131.9 N pull at 0.5 MPa, or 219.8 N push and 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
Yes. The -S suffix indicates a built-in piston magnet, allowing you to fit CMSG, DMSG or EMSG reed or electronic switches directly to the SUS304 stainless barrel for precise end-of-stroke detection.
