Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X80UFA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X80UFA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 80mm 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 MFC40X80UFA
Delivering 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore mini cylinder handles heavy loads with precision. A needle-adjustable variable air cushion at both ends absorbs high-speed end-of-stroke shock, protecting your machinery and cutting noise far better than a fixed bumper. The riveted aluminium covers and SUS304 stainless steel barrel resist mild corrosion and washdown environments.
For the same bore and stroke, this JIS-standard round-body unit is shorter than an ISO 6432 cylinder, saving valuable mounting length. It features an 80 mm stroke, a 1/4" air port, and an M14x1.5 male rod thread. Based on its 0.5 MPa push rating, it provides a safe working load of roughly 377 N and lifts about 32 kg vertically with a 2:1 margin. Note this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors without switching to an -S variant.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X80UFA Is Used
Heavy Package Diversion
Uses the 628.3 N push force to deflect heavy cartons at 800 mm/s, relying on the variable air cushion to silently absorb the 80 mm stroke impact.
Press Ejection
Pushes finished metal parts out of a press zone, where the FA flange secures the body and the cushion needle prevents shock from damaging the tooling.
Pallet Stopper
Halts loaded pallets on a roller line; the SUS304 stainless barrel withstands dust and moisture while the cushion softens the heavy end stop.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X80UFA the Right Cylinder?
If 628.3 N at 0.5 MPa is too much force, step down to the MFC32 bore which provides 402.2 N; since 40 mm is the largest available MFC size, you cannot size up within this series. The variable air cushion is essential when driving heavy payloads at high speeds up to 800 mm/s, allowing you to dial in the exact deceleration needed to prevent impact damage. This configuration includes a U flat-end back cover and an FA flange for secure mounting.
Remember that the air cushion only decelerates the piston near the stroke end and does not function as a lock or brake. If your application must hold a vertical load during air loss or when a valve is centred, the piston will drift, so you must add an external rod lock or a pilot-operated check valve. Additionally, because this non-S SKU has no internal magnet, position sensing is impossible on this specific unit.
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 MFC40X80UFA FAQ
This 40 mm bore cylinder features a 1/4" port and an M14x1.5 rod thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, 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, this specific SKU does not include an internal magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant of this round-body stainless steel cylinder to enable sensing.
