Airtac MF32-40 Stainless Steel Mini Cylinder MF32X75SUFA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X75SUFA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 75mm 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 MF32X75SUFA
Delivering 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder uses a SUS304 stainless steel barrel with riveted aluminium covers to resist mild corrosion and washdown. Because the MF body is shorter than an ISO 6432 cylinder for the same 32 mm bore and 75 mm stroke, it saves valuable mounting length in tight fixtures. The piston relies on a two-way oil-retaining seal for long life, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impact.
Air extends and retracts the Ø12 mm rod through a 1/4 inch port. Plan for about 241 N of real work at 0.5 MPa, which means it lifts about 20.5 kg vertically with a 2:1 safety margin. The built-in magnet (-S) supports CMSG, DMSG, and EMSG switches for position sensing.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X75SUFA Is Used
Clamping Machined Parts
Holds aluminium housings in a CNC milling fixture using the 402.2 N push force, while the compact JIS body clears the machining envelope.
Carton Flap Folding
Swings corrugated box flaps into position on a packaging line, where the SUS304 barrel withstands occasional washdowns.
Pallet Stopper Gate
Acts as a pneumatic stop for inbound pallets, using the U flat-end rear cover and FA flange to bolt securely to the conveyor frame.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X75SUFA the Right Cylinder?
If 245.3 N from the MF25 is too light and 628.3 N from the MF40 is excessive, this 32 mm bore hits the sweet spot at 402.2 N push. The included FA flange simplifies front mounting, and the U flat-end back cover provides a flush rear face for direct chassis bolting. Since the -S magnet is present, you can fit CMSG, DMSG, or EMSG sensors directly. For the 75 mm stroke, keep the load guided to prevent rod bending and side-load wear.
Remember that fixed TPU bumpers only decelerate the stroke end; they do not act as a brake. If air pressure drops or the valve centres, the piston will drift and drop the load. To secure a vertical load safely, 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 MF32X75SUFA FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N. At 0.7 MPa it pushes 563 N and pulls 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa. This 32 mm bore cylinder uses a 1/4 inch air port and an M10x1.25 male rod thread.
No, the piston will drift if air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the rod near the stroke end; they do not lock the load. You must add an external rod lock or pilot check valve to hold a suspended weight.
