Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X400CA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X400CA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 400mm 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 MFC20X400CA
Delivering 157 N of push force at 0.5 MPa, this double-acting 20 mm bore mini cylinder handles long 400 mm strokes with precision. The variable air cushion at both ends lets you dial in the needle to absorb high-speed end-of-stroke shock, protecting your payload and cutting noise. A JIS-standard round-body design, it is notably shorter than an ISO 6432 cylinder for the same bore and stroke, saving valuable mounting length.
Built with a SUS304 stainless steel barrel and riveted aluminium covers, it resists mild corrosion and washdown environments. This specific SKU lacks the -S magnet and therefore cannot accept CMSG, DMSG, or EMSG sensors. For vertical lifting, it handles about 8 kg safely with a 2:1 margin, while the rear CA pivot cover simplifies articulated rod-end mounting.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X400CA Is Used
Long-Reach Transfer
Uses the full 400 mm stroke to push light workpieces between conveyor lanes, relying on the tuned air cushion to stop the 8 mm rod smoothly without slamming.
High-Speed Sorting
Deflects small items at high cycle rates where the 157 N push force is sufficient, and the adjustable cushioning prevents bounce at the end of travel.
Pivot-Actuated Gating
Leverages the rear CA pivot cover to swing a guide gate, with the SUS304 barrel enduring occasional splashes in light-duty manufacturing cells.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X400CA the Right Cylinder?
When sizing this 20 mm bore actuator, step down if payloads are light or step up to the MFC25 if you need more force—the MFC25 yields 245.3 N at 0.5 MPa compared to this model's 157 N. The adjustable air cushion is essential when operating at high speeds or moving heavy masses, as it decelerates the piston smoothly near stroke end.
Note that the cushion only slows the piston and does not function as a lock or brake. Because a standard cylinder drifts when air pressure drops or valves center, you must add an external rod lock or pilot-operated check valve for fail-safe load holding. Additionally, without the -S magnet option, this version cannot support magnetic 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 MFC20X400CA FAQ
This 20 mm bore 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, 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.
No, this specific SKU does not include the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for magnetic sensing. The unit does feature a SUS304 stainless barrel and a CA rear pivot cover for corrosion-resistant articulated mounting.
