Airtac MF32-40 Stainless Steel Mini Cylinder MF32X250SU
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X250SU is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 250mm 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 MF32X250SU
Generating 402.2 N of push force at 0.5 MPa, the AirTAC MF32X250SU is a JIS-standard round-body mini cylinder engineered for tight assembly layouts. Because its riveted rolling-packed structure is physically shorter than a comparable ISO 6432 unit of the same 32 mm bore and 250 mm stroke, it directly saves valuable mounting length on your machinery. The SUS304 stainless steel barrel pairs with aluminium covers to resist mild corrosion and routine washdowns.
This double-acting actuator uses a two-way oil-retaining piston seal for long service life and features fixed TPU bumper pads to soften stroke-end impacts. Equipped here with a piston magnet (-S) and a U flat-end back cover, it supports position sensing via CMSG, DMSG or EMSG switches. For practical sizing, plan for roughly 241 N of real work at 0.5 MPa, which means it can safely lift a 20.5 kg vertical load with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X250SU Is Used
Package Diverting
Pushes medium-weight cartons off a sorting line using 402.2 N of thrust at 0.5 MPa, with the U flat-end cover mounted flush to the conveyor frame.
Vertical Parts Lift
Elevates 20 kg component trays between processing tiers, taking advantage of the 250 mm stroke while maintaining a 2:1 lift safety margin.
Clamp Actuation
Secures aluminium extrusions in a machining cell where the SUS304 stainless barrel withstands mild coolant washdown.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X250SU the Right Cylinder?
When sizing this 32 mm bore, stepping down to the MF25 yields 245.3 N of push at 0.5 MPa, while stepping up to the MF40 provides 628.3 N. The MF32X250SU hits a solid middle ground for mid-range actuation. It carries a 1/4" port and an M10x1.25 male rod thread. The U flat-end rear cover suits direct bulkhead mounting, and the -S magnet enables electronic or reed sensor tracking.
Because this model uses a 250 mm stroke, be mindful of rod bending under heavy side loads and ensure proper guiding. Note that a standard cylinder drifts when air is removed or a valve is centred; the TPU bumpers only decelerate the stroke end and do not function as a braking lock. To suspend a 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 MF32X250SU FAQ
The 32 mm bore provides 402.2 N push and 345.6 N pull at 0.5 MPa, or 563 N push and 483.8 N pull at 0.7 MPa. 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.
It features a SUS304 stainless barrel with riveted aluminium covers, making the body shorter than an ISO 6432 cylinder for the same stroke. The -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG switches. Fixed TPU bumper pads decelerate the stroke ends but do not provide adjustable cushioning.
