Airtac MF32-40 Stainless Steel Mini Cylinder MF32X25U
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X25U is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 25mm 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 MF32X25U
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore JIS-standard round-body mini cylinder features a SUS304 stainless-steel barrel with riveted aluminium covers that resist mild corrosion and washdown. Because the MF body is shorter than an ISO 6432 cylinder for the same 25 mm stroke, it fits tighter fixtures and saves valuable mounting length.
The piston relies on a heterogeneous two-way seal that retains an oil film for long life, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impact. For practical sizing, 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. This U-style unit has a 1/4" port and an M10x1.25 male rod thread.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X25U Is Used
Clamping Machined Parts
Holds aluminium housings securely during CNC milling operations using its 241 N safe working force.
Short-Stroke Sealing
Presses carton flaps and film wrappers with its 25 mm stroke and flat-end U rear cover in compact packaging lines.
Ejecting Molded Components
Pushes plastic parts out of small injection molds where the shorter JIS body saves machine envelope space.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X25U the Right Cylinder?
If 245.3 N from the MF25 at 0.5 MPa is insufficient, this 32 mm bore provides a solid step up; should you need even more power, the MF40 offers 628.3 N at the same pressure. The 25 mm stroke keeps the rod compact, but always guide the load to prevent side-load bending. Without external valving, air loss or a centred valve will let the piston drift, as the fixed bumpers only decelerate the end of travel rather than locking the load. Use a pilot-operated check valve or external rod lock if you need to hold position. Note that this specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.
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 MF32X25U 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. The air port is 1/4" and the male rod thread is M10x1.25.
No, this SKU does not have the -S magnet option, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. The U flat-end back cover allows direct rear mounting, and the fixed TPU bumper pads simply decelerate the stroke end without acting as an adjustable cushion.
