Airtac MF32-40 Stainless Steel Mini Cylinder MF32X400SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X400SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 400mm 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 MF32X400SCM
Generating 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore unit handles demanding 400 mm travel tasks. The JIS-standard round-body architecture is physically shorter than a comparable ISO 6432 cylinder, delivering a noticeable packaging advantage in tight machinery. A built-in magnet (-S) allows seamless integration with CMSG, DMSG, or EMSG switches for position sensing.
The SUS304 stainless steel barrel and riveted aluminium covers shrug off mild corrosion and washdown environments. Inside, a heterogeneous two-way seal retains an oil film for long service life, while fixed TPU bumper pads and a front-cover anti-impact pad absorb stroke-end shock. Plan for roughly 241 N of actual work at 0.5 MPa, or expect it to safely lift about 20.5 kg vertically with a 2:1 safety margin. The 1/4 inch port matches the 32 mm bore specification.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X400SCM Is Used
Carton Flap Folding
Pushes corrugated packaging flaps on a continuous conveyor line, utilising the 400 mm stroke to clear varying box widths before taping.
Vertical Parts Elevator
Lifts approximately 20.5 kg component trays between machinery tiers, relying on the 402.2 N output to overcome gravity reliably.
Guard Door Actuation
Opens and closes heavy CNC safety enclosures, where the shorter JIS body saves axial space without sacrificing the 32 mm bore strength.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X400SCM the Right Cylinder?
When sizing this 32 mm bore, dropping down to an MF25 reduces the push force to 245.3 N at 0.5 MPa, whereas stepping up to an MF40 increases it to 628.3 N. This model uses a CM round-end back cover and a 400 mm stroke, which approaches the 500 mm standard maximum; at this length, ensure your mounting configuration—whether LB foot, FA flange, or TC trunnion—prevents rod side-loading and bending.
Because the fixed TPU bumpers only decelerate the impact near the stroke end, they cannot function as a brake. If air pressure drops or the valve is centred, the piston will drift and drop the load. To maintain vertical position securely, fit 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 MF32X400SCM FAQ
At 0.5 MPa it pushes with 402.2 N and pulls with 345.6 N. At 0.7 MPa the push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa. The air port is 1/4 inch, the rod is 12 mm, and the male rod thread is M10x1.25.
No, the fixed TPU bumper pads only soften the stroke end and do not act as a lock. The piston will drift if air is lost or the valve is centred. You must use an external rod lock or pilot check valve to hold a vertical load. The -S magnet allows CMSG, DMSG, or EMSG sensors to track position.
