Airtac MF32-40 Stainless Steel Mini Cylinder MF32X350SU
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X350SU is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 350mm 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 MF32-40 Stainless Steel Mini Cylinder MF32X350SU
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MF32X350SU is a JIS-standard round-body mini cylinder engineered for compact automation. Its SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments. Because this riveted body is physically shorter than an ISO 6432 cylinder of the identical bore and stroke, it saves valuable mounting length in tight machinery. The 1/4" port and M10x1.25 male rod thread ensure straightforward pneumatic integration.
This 32 mm bore, 350 mm stroke unit operates double-acting with fixed TPU bumper pads that soften stroke-end impact without offering adjustable cushioning. Planning for about 241 N of real work at 0.5 MPa leaves a safe performance margin, and the piston can vertically lift approximately 20.5 kg with a 2:1 safety factor. The internal two-way seal retains an oil film for long mechanical life, and the built-in -S magnet enables position sensing.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X350SU Is Used
Carton Flap Folding
Provides the 402.2 N push at 0.5 MPa needed to fold heavy cardboard flaps on packaging lines, with the 350 mm stroke reaching across wide boxes.
Vertical Parts Ejection
Lifts finished machined parts weighing up to 20.5 kg out of a fixture, using the built-in magnet to trigger a downstream sensor upon full extension.
Textile Beam Shifting
Shifts heavy textile beams laterally between processing stations, where the SUS304 stainless barrel withstands humid dye-house environments.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X350SU the Right Cylinder?
When sizing this 32 mm bore, the smaller MF25 generates 245.3 N of push force at 0.5 MPa, while the larger MF40 provides 628.3 N, giving you clear scaling steps if your load changes. The U flat-end back cover on this SKU suits direct rear mounting, and the -S magnet allows CMSG, DMSG, or EMSG switches for end-of-stroke confirmation. For this 350 mm stroke, ensure your mounting configuration—such as an FA flange or TC trunnion—adequately supports the rod to prevent side-loading and premature bending.
Note that a standard double-acting cylinder drifts when air pressure is lost or the directional valve is centred; the TPU bumpers only decelerate the stroke end and do not function as a locking brake. If your application requires vertical load holding on air loss, install an external rod lock or a pilot-operated check valve.
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 MF32-40 Stainless Steel Mini Cylinder MF32X350SU FAQ
This 32 mm bore cylinder features a 1/4" air port and an M10x1.25 male rod thread. It generates 402.2 N of push force and 345.6 N of pull force at 0.5 MPa. At 0.7 MPa, the push increases to 563 N and the pull to 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
The MF32X350SU is a JIS-standard round-body cylinder that is physically shorter than an ISO 6432 cylinder for the same bore and stroke, saving mounting length. It uses fixed TPU bumper pads to decelerate the stroke end rather than an adjustable air cushion. The U flat-end back cover allows direct mounting, and the -S magnet supports CMSG, DMSG, or EMSG sensors.
