Airtac MF32-40 Stainless Steel Mini Cylinder MF32X5SU
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X5SU is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 5mm 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 MF32X5SU
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore JIS-standard round-body mini cylinder is built for compact automation. Its SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments. The riveted rolling-packed structure keeps the overall body shorter than a comparable ISO 6432 unit, saving valuable mounting length in tight fixtures.
The piston relies on a heterogeneous two-way seal that retains an oil film for long service life, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts. Because the code includes an S, this unit has a built-in magnet for position sensing. For practical sizing, plan for a safe working load of roughly 241 N, which lets you lift about 20.5 kg vertically with a 2:1 safety margin. The U flat-end back cover provides a flush rear mounting face, and the 1/4" port handles the air supply.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X5SU Is Used
Short-Stroke Clamping
Ideal for holding aluminium extrusions in a machining fixture, using the 402.2 N push force to secure the part without deflecting it.
Ejector Pins
Provides a fast 5 mm kick to eject small moulded plastic components from an assembly die using the U flat-end rear mount.
Gate Diverter
Pivots a small guide flap on a packaging line to sort lightweight cartons, benefiting from the compact JIS body length.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X5SU the Right Cylinder?
When sizing this 32 mm bore, compare it directly against its neighbours: the MF25 provides 245.3 N of push at 0.5 MPa, while the MF40 steps up to 628.3 N. Choose this 32 mm model when you need moderate thrust in a very short 5 mm stroke. The fixed TPU bumpers decelerate the piston near the stroke ends but do not function as a lock; if your application must hold a vertical load when air is lost or the valve is centred, add an external rod lock or a pilot-operated check valve to prevent drift. The built-in -S magnet allows you to mount CMSG, DMSG, or EMSG switches directly onto the stainless barrel for precise end-of-stroke detection. For mounting flexibility, you can pair the U flat-end back cover with LB foot, FA flange, SDB pivot, or TC trunnion brackets.
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 MF32X5SU FAQ
At 0.5 MPa it pushes with 402.2 N and pulls with 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" air port and a male M10x1.25 rod thread.
It does not conform to ISO 6432, though its JIS-standard riveted round body is intentionally shorter than an ISO 6432 cylinder for the same bore and stroke, saving space. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors. It uses fixed TPU bumper pads rather than an adjustable air cushion.
