Airtac MF32-40 Stainless Steel Mini Cylinder MF40X50CMFA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X50CMFA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 50mm 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 MF40X50CMFA
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy-duty tasks within tight fixtures. Its SUS304 stainless-steel barrel and riveted aluminium covers resist mild corrosion and washdown, while the piston's two-way seal retains an oil film for long service life. For practical sizing, plan for about 377 N of real work at 0.5 MPa, which means it lifts about 32 kg vertically with a 2:1 safety margin.
The body is purposefully shorter than an ISO 6432 cylinder for the same 40 mm bore and 50 mm stroke, yielding a real packaging win. It uses fixed TPU bumper pads alongside a front-cover anti-impact pad to soften stroke-end impact, and because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches. Air connects via a 1/4" port.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X50CMFA Is Used
Stamping Pin Ejection
Provides the 628.3 N push force needed to knock jammed stamping pins out of a progressive die block.
Heavy Cart Diversion
Uses the FA flange to mount rigidly and push heavy cardboard cartons onto a secondary packaging line.
Pallet Component Pressing
Presses bearing housings into pallet assemblies, where the short JIS body saves valuable machine depth.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X50CMFA the Right Cylinder?
When sizing this 40 mm bore, step down to the MF32 if your task requires only 402.2 N of push at 0.5 MPa, as 40 mm is the largest available MF diameter. This model includes a CM round-end back cover and an FA flange for direct mounting. If your mechanism lifts a vertical load, remember that a plain cylinder drifts when air is lost or the valve is centred; the TPU pads only decelerate the stroke end and act as neither a lock nor a brake. You must add an external rod lock or a pilot-operated check valve to hold the payload securely.
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 MF40X50CMFA FAQ
This 40 mm bore cylinder features a 1/4" port and an M14x1.5 male rod thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum force of 128.1 kgf at 1.0 MPa.
No, this specific SKU lacks the internal magnet so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. It features fixed TPU bumper pads that decelerate the stroke end, and its riveted stainless round-body is shorter than an ISO 6432 cylinder.
