Airtac MF32-40 Stainless Steel Mini Cylinder MF40X500CM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X500CM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 500mm 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 MF40X500CM
Delivering 628.3 N of push force at 0.5 MPa, the AirTAC MF40X500CM is a double-acting JIS-standard round-body mini cylinder built for demanding actuation. Its SUS304 stainless steel barrel and riveted aluminium covers shrug off mild corrosion and washdown environments. Because this MF body is shorter than an ISO 6432 cylinder for the same 40 mm bore and 500 mm stroke, it saves valuable mounting length in tight machinery. The piston relies on a two-way oil-retaining seal for long life, while fixed TPU bumper pads and a front-cover anti-impact pad soften the stroke-end impact.
Featuring a 1/4" air port and an M14x1.5 male rod thread, this unit is engineered for substantial work. Plan for about 377 N of real work at 0.5 MPa, which safely lifts roughly 32 kg vertically with a 2:1 margin. The CM round-end back cover simplifies rear pivot mounting. Note that this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors without upgrading to the -S variant.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X500CM Is Used
Pallet Diverters
Pushes heavy pallets across transfer lines using 628.3 N of thrust at 0.5 MPa, with the 500 mm stroke clearing wide conveying lanes.
Carton Flap Folders
Folds large corrugated carton flaps during automated case sealing, where the short JIS body prevents interference with folding mechanics.
Stamping Ejectors
Ejects formed metal parts from light stamping presses, relying on the SUS304 barrel to withstand occasional cutting fluid splash.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X500CM the Right Cylinder?
When sizing this 40 mm bore, compare it directly with its neighbours: the MF32 delivers 402.2 N at 0.5 MPa if your load is lighter, while the MF40 provides the 628.3 N needed for heavier pushing. Because this is the largest bore in the MF series, you must split the workload or switch to a different cylinder family for forces exceeding 128.1 kgf at 1.0 MPa. Keep in mind that a standard cylinder drifts if air pressure drops or the valve is centred; the TPU bumpers only decelerate the stroke end and will not lock the load. Use an external rod lock or pilot-operated check valve for secure holding. The CM rear cover pairs well with pivot mounts, but at 500 mm you must carefully manage side loads to avoid rod bending.
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 MF40X500CM FAQ
This 40 mm bore cylinder features a 1/4" port and an M14x1.5 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 does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You must select the -S variant for sensing capabilities. The CM round-end back cover allows rear pivot mounting, and the fixed TPU bumpers decelerate the rod but do not function as an adjustable air cushion.
