Airtac MF32-40 Stainless Steel Mini Cylinder MF32X450SU
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X450SU is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 450mm 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 MF32X450SU
Generating 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore cylinder handles a 450 mm travel requirement efficiently. Because the JIS-standard round-body design is physically shorter than a comparable ISO 6432 unit, it saves valuable mounting length in tight machinery. The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion, while the piston's two-way seal retains an oil film for extended lifespan. A flat-end U back cover provides a flush rear mounting face for direct bolting.
Equipped with a built-in magnet, the unit supports CMSG, DMSG, and EMSG position switches. For practical sizing, plan for roughly 241 N of actual work at 0.5 MPa, which translates to lifting about 20.5 kg vertically with a 2:1 safety margin. The 1/4 inch port and M10x1.25 male rod thread accommodate steady airflow for high cycle rates. Fixed TPU bumper pads and a front-cover anti-impact pad absorb stroke-end shock across the 450 mm travel.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X450SU Is Used
Carton Flap Folding
Pushes corrugated packaging flaps on a continuous packaging line, utilising the 450 mm stroke to clear varying box widths before the sealing head.
Vertical Parts Ejection
Ejects machined aluminium components from a vertical fixture, safely handling parts weighing up to 20 kg with the recommended safety margin.
Textile Beam Shifting
Translates heavy textile beams laterally between processing stations, where the SUS304 barrel withstands humid environments.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X450SU the Right Cylinder?
When sizing this 32 mm bore, verify your actual load requirements against the 402.2 N push rating at 0.5 MPa. If your application demands less force, stepping down to the MF25 yields 245.3 N, whereas moving up to the MF40 provides 628.3 N for heavier payloads. The generous 450 mm stroke is well within the 500 mm standard limit, though at this length you should ensure the load is guided to prevent rod bending and premature seal wear.
This SKU includes the S magnet for sensing and a U flat-end rear cover for straightforward face-mounting. Remember that standard double-acting cylinders drift when air pressure is removed or the valve is centred; the bumpers only decelerate the stroke end and will not hold a load. To maintain vertical position during an air loss, integrate an external rod lock or a pilot-operated check valve into your circuit.
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 MF32X450SU FAQ
The 32 mm bore generates 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, with a theoretical maximum of 82 kgf at 1.0 MPa. It uses a 1/4 inch air port and an M10x1.25 male rod thread.
Yes, the model code includes an S, meaning it has a built-in piston magnet ready for CMSG, DMSG, or EMSG switches. The JIS-standard round-body is shorter than an ISO 6432 cylinder for the same stroke, and the fixed TPU bumpers simply decelerate the stroke end rather than acting as an adjustable cushion.
