Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X350CA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X350CA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 350mm 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 MFC20X350CA
Designed with a CA rear pivot, the AirTAC MFC20X350CA is a 350 mm stroke double-acting mini cylinder built around a JIS-standard round body. Its SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown, while the variable air cushion at both ends lets you dial in the deceleration to protect equipment at high speeds.
In the 20 mm bore class, this actuator generates a push force of 157 N and a pull force of 131.9 N at 0.5 MPa. Derived from that 157 N rating, it handles a safe working load of roughly 94 N, or lifts about 8 kg vertically with a 2:1 safety margin. It operates on a 1/8" port at speeds of 30-800 mm/s, and for the same envelope, its body is shorter than an ISO 6432 cylinder.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X350CA Is Used
Pivot-Driven Part Pusher
Uses the CA rear pivot to swing and push light 8 kg assemblies along a conveyor, relying on the 157 N thrust and tuned cushions to prevent end-of-stroke bounce.
High-Speed Divert Gate
Cycles rapidly across the 350 mm stroke to divert packages; the adjustable air cushions absorb the shock of fast direction changes without needing bumpers.
Vertical Lift Stopper
Raises and lowers a lightweight 94 N safety stop in a storage module, taking advantage of the SUS304 stainless barrel in mildly humid warehouse conditions.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X350CA the Right Cylinder?
When sizing this 20 mm bore actuator, step down if your payload is light or step up to the MFC25, which provides a 245.3 N push force at 0.5 MPa. The adjustable needle cushions are essential for the 350 mm stroke when moving heavier masses at high velocity, as they soak up end-of-stroke impact. Note that this SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG position switches; order a -S variant if you require sensing. Furthermore, the cushion only decelerates the load near the stroke end—it is not a brake. If you need to prevent drift on air loss, install an external rod lock or pilot check valve. Mounting options include LB foot, FA flange, SDB pivot-block and TC trunnion.
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 MFC20X350CA FAQ
This 20 mm bore cylinder features a 1/8" port and an M8x1.25 male rod thread. At 0.5 MPa it delivers a 157 N push and 131.9 N pull force. At 0.7 MPa the push is 219.8 N and the pull is 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet option, meaning it cannot accept CMSG, DMSG or EMSG switches. You would need the -S variant for sensing. The cylinder does feature a variable air cushion at both ends to decelerate loads, but this is not a locking mechanism.
