Airtac MF32-40 Stainless Steel Mini Cylinder MF40X5CM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X5CM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 5mm 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 MF40X5CM
Delivering 628.3 N of push force at 0.5 MPa, this 40 mm bore double-acting JIS-standard round-body cylinder is built for high-impact short-stroke clamping. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown, while the internal two-way seal retains an oil film for extended mechanical life. Because the MF body is shorter than an ISO 6432 cylinder for the same envelope, it fits tighter machine fixtures. The 1/4" port and M14x1.5 male rod thread accommodate robust pneumatic supply and heavy mounting clevises.
Fixed TPU bumper pads and a front-cover anti-impact pad absorb the sudden shock of the 5 mm stroke end, decelerating the load without adjustable cushioning. Plan for roughly 377 N of actual work at 0.5 MPa to maintain a safe margin, which equates to lifting about 32 kg vertically against gravity. This specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG reed switches for position sensing.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X5CM Is Used
Stamping Pin Ejection
Uses the 5 mm rapid stroke to eject small stamped metal pins from a die, relying on the 628.3 N push force to overcome die friction.
Package Flap Folding
Deploys instantly to fold carton flaps on a high-speed packaging line, where the short JIS body prevents interference with moving conveyor belts.
Pallet Component Snugging
Presses lightweight cardboard dividers against palletized goods to square the load before stretch wrapping, utilizing the front anti-impact pad.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X5CM the Right Cylinder?
When sizing this actuator, compare its 628.3 N push force at 0.5 MPa against the smaller MF32, which yields 402.2 N under identical pressure. Since 40 mm is the largest available bore in the MF family, stepping up further requires a different cylinder series entirely. The CM round-end back cover suits rear pivot mounting, complemented by LB foot, FA flange, SDB pivot, or TC trunnion brackets. Because the 5 mm travel is extremely short, rod-bending side loads are minimal if the load is axially aligned.
If your process requires the piston to stay put when air pressure drops or the directional valve centres, note that this base cylinder will drift. The fixed bumpers only soften the end-of-stroke impact and act purely as deceleration pads, never as a locking mechanism. To suspend a load safely, install an external rod lock or incorporate a pilot-operated check valve into the 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 MF40X5CM FAQ
At 0.5 MPa it pushes with 628.3 N and pulls with 527.8 N. At 0.7 MPa the push increases to 879.6 N and the pull to 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa. This 40 mm bore unit uses a 1/4" pneumatic port.
No, this specific SKU does not include the -S magnet option, meaning it cannot host CMSG, DMSG, or EMSG switches. You would need the -S variant for magnetic sensing. It features a CM round-end back cover and a SUS304 stainless barrel that is physically shorter than a comparable ISO 6432 unit.
