Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X225SU
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X225SU is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 225mm 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 MFC40X225SU
Delivering 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore mini cylinder handles heavy loads with precision. The MFC40X225SU features a variable air cushion at both ends, allowing you to dial in the needle valve to absorb end-of-stroke shock during high-speed operations. Its SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments.
For the same bore and stroke, this JIS-standard round-body cylinder is notably shorter than an ISO 6432 unit, saving valuable machine space. It includes a built-in piston magnet (-S) for position sensing and a flat-end U rear cover. Operating at speeds from 30 to 800 mm/s, it provides a safe working load of roughly 377 N, lifting about 32 kg vertically with a 2:1 margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X225SU Is Used
Heavy Package Diversion
Uses the 879.6 N push force at 0.7 MPa to positively redirect heavy cartons on a high-speed sorter, with the adjustable cushion preventing load damage at stroke end.
Vertical Press Lowering
Lowers a 32 kg assembly head smoothly using the 225 mm stroke, relying on the needle-set air cushion to decelerate the mass before contact without bouncing.
Pallet Flap Folding
Drives large cardboard flaps down on a washdown-capable packaging line, benefiting from the SUS304 barrel and the compact JIS body length.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X225SU 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 this is the largest available bore in the series. The variable air cushion is essential here for heavy or fast-moving loads, but remember it only decelerates the piston near the stroke end—it does not function as a brake. If you need to hold a load vertically during air loss, install an external rod lock or pilot check valve.
This configuration ships with a 1/4 inch port, an M14x1.5 male rod thread, and a flat-end U back cover. Because it carries the -S suffix, you can directly mount CMSG, DMSG, or EMSG sensors for reed or electronic switching. Choose from LB foot, FA flange, SDB pivot, or TC trunnion mounts to fit your frame.
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 MFC40X225SU FAQ
This 40 mm bore cylinder features a 1/4 inch port and an M14x1.5 male 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.
Yes, the -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG sensors. However, the variable air cushion only decelerates the piston near the stroke end and does not act as a lock; you must use an external rod lock or pilot check valve to hold a load vertically.
