Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X200SU
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X200SU is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 200mm stroke, 1/4" 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 MFC40X200SU
Delivering 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore mini cylinder handles demanding actuation with ease. The MFC40X200SU features a variable air cushion at both ends, allowing you to turn a needle valve to precisely soak up end-of-stroke shock at high speeds, protecting your payload and cutting noise. Its JIS-standard round-body construction pairs a SUS304 stainless steel barrel with riveted aluminium covers, offering excellent mild corrosion and washdown resistance.
For the same bore and stroke, this riveted stainless design is noticeably shorter than a standard ISO 6432 cylinder, saving valuable mounting length. Equipped with a U flat-end back cover and a 1/4" port, it supports a safe working load of roughly 377 N. With a built-in piston magnet (-S), it is fully compatible with CMSG, DMSG, and EMSG switches for position sensing.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X200SU Is Used
Heavy Package Diversion
Uses the 628.3 N push force to positively redirect heavy cartons at high speed, while the needle-set air cushion prevents harsh slams at the 200 mm stroke end.
Pallet Flap Folding
Drives large cardboard flaps down on a washdown-ready packaging line, benefiting from the SUS304 stainless barrel and U flat-end back cover for tight machine frames.
Vertical Lift Gate
Lifts about 32 kg vertically with a 2:1 safety margin, relying on the adjustable cushion to smoothly settle the gate without bouncing at the top position.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X200SU the Right Cylinder?
When sizing this 40 mm bore, step down to the MFC32 if your application only requires 402.2 N of push force at 0.5 MPa, as 40 mm is the largest available bore in the MFC series. The variable air cushion is essential if you are moving heavy loads at high speeds up to 800 mm/s, preventing harsh impacts at the stroke ends.
Remember that the air cushion only decelerates the piston near the end of travel; it does not function as a lock or brake. If your system loses air or the valve is centered, the piston will drift, so you must add an external rod lock or pilot-operated check valve to hold a suspended load safely. The included -S magnet enables CMSG, DMSG, or EMSG sensors, and you can mount it using LB foot, FA flange, SDB pivot, or 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 MFC40X200SU FAQ
This 40 mm bore cylinder features a 1/4" air port and a 16 mm rod with an M14x1.5 male thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, increasing to 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum force of 128.1 kgf at 1.0 MPa.
No, the variable air cushion only decelerates the piston near the stroke end and acts purely as a shock absorber, never as a brake or lock. If air is lost, the piston will drift, so you must fit an external rod lock or pilot check valve for suspended loads. The built-in -S magnet allows CMSG, DMSG, and EMSG sensors to confirm position.
