Airtac MF32-40 Stainless Steel Mini Cylinder MF32X35U
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X35U is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 35mm 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 MF32X35U
Delivering 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles substantial work in tight spaces. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown, while the two-way piston seal retains an oil film for long service life. Because the MF body is shorter than an ISO 6432 cylinder for the same 32 mm bore and 35 mm stroke, it saves valuable mounting length.
Plan for about 241 N of actual work at 0.5 MPa, which safely lifts roughly 20.5 kg vertically with a 2:1 margin. The front cover integrates a fixed anti-impact pad alongside internal TPU bumpers to decelerate the stroke end. This specific U-style configuration features a flat-end back cover, and since it lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG switches.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X35U Is Used
Stamping Pin Ejection
Uses the 402.2 N push force to eject small stamped metal pins from a progressive die bed in under a second.
Bottle Lane Diversion
Extends 35 mm to actuate a flat guide plate, shifting plastic bottles between parallel packaging lanes.
Carton Flap Holding
Maintains downward pressure on corrugated carton flaps while an upstream tape head seals the package.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X35U the Right Cylinder?
When sizing this 32 mm bore, stepping down to the MF25 yields 245.3 N at 0.5 MPa, while stepping up to the MF40 provides 628.3 N. This model uses a 1/4" port and an M10x1.25 male rod thread. The fixed TPU bumpers absorb stroke-end impact but do not function as an adjustable air cushion; for high-speed cycling, consider the MFC variant.
Because this SKU lacks a magnet, position sensing is impossible without upgrading to an -S version. If your application requires the rod to stay put during air loss or valve centring, note that the piston will drift; add an external rod lock or pilot check valve. The short 35 mm stroke minimizes rod-bending side loads, making it ideal for compact clamping.
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 MF32X35U 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. This 32 mm bore cylinder uses a 1/4" air port and an M10x1.25 male rod thread.
No, this specific SKU lacks a piston magnet, so it cannot accept CMSG, DMSG or EMSG switches. You must order the -S variant for sensing. It features a U flat-end rear cover, and its JIS-standard riveted body is physically shorter than an ISO 6432 cylinder of the same bore and stroke.
