Airtac MF32-40 Stainless Steel Mini Cylinder MF32X375SU
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X375SU is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 375mm 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 MF32X375SU
Generating 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder features a SUS304 stainless barrel with riveted aluminium covers that resist mild washdown. Because the MF body is shorter than an ISO 6432 cylinder for the same 375 mm stroke, it fits tighter fixtures and saves valuable machine length.
The 32 mm bore connects via a 1/4" port and uses an M10x1.25 male rod thread. Its heterogeneous two-way seal retains an oil film for long life, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts. Plan for about 241 N of actual work at 0.5 MPa, which means it lifts about 20.5 kg vertically with a 2:1 margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X375SU Is Used
Carton Flap Folding
Pushes corrugated packaging flaps on a continuous carton sealing line using its 375 mm stroke and 402.2 N push force at 0.5 MPa.
Vertical Parts Lift
Elevates 20 kg electronic component trays between conveyor tiers, taking advantage of the compact JIS body length to fit tight vertical spaces.
Press Ejection
Kicks stamped metal blanks out of a small pneumatic press using the U flat-end cover for stable rear mounting against the machine frame.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X375SU the Right Cylinder?
When sizing this 32 mm bore, the smaller MF25 provides 245.3 N at 0.5 MPa, while the larger MF40 offers 628.3 N at 0.5 MPa. The 375 mm stroke is well within the 500 mm standard limit, but at this length you should watch for side loads to prevent rod bending. The U flat-end back cover suits direct rear mounting.
If air pressure drops or the valve is centred, the piston drifts because the TPU pads only decelerate the stroke end rather than locking the load. To hold a vertical position securely, add an external rod lock or a pilot-operated check valve. The built-in -S magnet supports CMSG, DMSG and EMSG switches for position sensing.
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 MF32X375SU FAQ
This 32 mm bore double-acting cylinder uses a 1/4" port. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum force of 82 kgf at 1.0 MPa.
No, the piston will drift if air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. You must use an external rod lock or pilot check valve to hold a load securely.
