Airtac MF32-40 Stainless Steel Mini Cylinder MF32X65U
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X65U is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 65mm 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 MF32X65U
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore cylinder handles demanding clamping and lifting tasks. The JIS-standard round-body construction is physically shorter than a comparable ISO 6432 unit, saving valuable mounting length in tight machinery. Its SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments.
The internal piston relies on a two-way oil-retaining seal for smooth, long-lasting operation, while fixed TPU bumper pads and a front-cover anti-impact pad absorb stroke-end shock. Plan for a safe working load of roughly 241 N, which safely lifts about 20.5 kg vertically with a 2:1 margin. This specific SKU lacks a magnet and therefore cannot support position sensing; adding an -S variant enables CMSG, DMSG, or EMSG switches.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X65U Is Used
Stamping Pin Ejection
Uses the 402.2 N push force to eject small stamped metal pins from a die bed, where the 65 mm stroke provides just enough clearance for robotic retrieval.
Package Divert Arm
Actuates a routing arm on a packaging conveyor, leveraging the compact JIS body length to fit within narrow transfer chassis side-panels.
Carton Flap Folder
Folds secondary cardboard flaps prior to case sealing, taking advantage of the SUS304 stainless barrel to endure occasional washdown in food packing lines.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X65U the Right Cylinder?
When sizing this 32 mm bore, verify your actual load requirements against the 402.2 N push force at 0.5 MPa. If your application is lighter, stepping down to the MF25 provides 245.3 N and saves space, whereas heavy-duty tasks might require the MF40 at 628.3 N. This model features a U flat-end back cover, so ensure your mounting geometry accommodates that rear profile alongside standard LB, FA, SDB, or TC brackets.
Because this is a standard double-acting cylinder, the piston will drift if air pressure drops or the valve is centred; the TPU bumpers only decelerate the stroke end and do not function as a brake. To suspend a load safely mid-stroke, integrate an external rod lock or a pilot-operated check valve into your pneumatic 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 MF32X65U FAQ
This 32 mm bore cylinder features a 1/4" air port and an M10x1.25 male rod thread. At 0.5 MPa it generates 402.2 N of push force and 345.6 N of pull force. At 0.7 MPa, push increases to 563 N and pull to 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
This specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches; you must select an -S variant for position sensing. Regarding dimensions, the JIS-standard riveted round-body design is physically shorter than an ISO 6432 cylinder of the same bore and stroke, saving mounting space without conforming to the ISO standard.
