Airtac MF32-40 Stainless Steel Mini Cylinder MF40X15CM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X15CM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 15mm 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 MF40X15CM
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy-duty clamping in tight spaces. The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown, while the piston's two-way oil-retaining seal ensures long service life. For practical sizing, plan for around 377 N of real work at 0.5 MPa, which means it lifts about 32 kg vertically with a 2:1 safety margin.
Because the MF body is shorter than an ISO 6432 cylinder for the same 40 mm bore and 15 mm stroke, it saves valuable mounting length in compact fixtures. The unit features fixed TPU bumper pads and a front-cover anti-impact pad that soften stroke-end impact without offering adjustable cushioning. This specific SKU lacks a magnet and therefore cannot support CMSG, DMSG, or EMSG sensors, and it carries a CM round-end rear cover.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X15CM Is Used
Stamping Press Ejection
Uses the 628.3 N push force to knock stamped metal parts out of a die quickly within a tight 15 mm stroke.
Heavy Package Diverter
Pushes dense cartons off a main conveyor belt using the short 15 mm stroke to save machine footprint.
Pallet Stopper Gate
Acts as a heavy-duty stop block for pallets, relying on the CM round-end cover for rear pivot flexibility.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X15CM the Right Cylinder?
When sizing this 40 mm bore, consider the MF32 which pushes 402.2 N at 0.5 MPa if your load is lighter, as there is no larger bore in the MF series. This SKU has no -S magnet, so it cannot accept position switches; choose an -S variant if you need sensing. The 1/4" port and M14x1.5 male rod thread match the bore standard. For this very short 15 mm stroke, side-load risks are minimal, but ensure rigid mounting using LB foot, FA flange, or TC trunnion brackets.
Remember that a plain cylinder drifts if air is lost or the valve is centred. The TPU pads only decelerate the stroke end and do not function as a brake. To maintain vertical position during an air failure, install 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 MF40X15CM FAQ
The 40 mm bore has a 1/4" air port and an M14x1.5 male rod thread. It pushes 628.3 N and pulls 527.8 N at 0.5 MPa. At 0.7 MPa, push is 879.6 N and pull is 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
No, this specific SKU lacks the internal magnet required for switches. You must select an MF40 model with the -S suffix to use CMSG, DMSG, or EMSG sensors. The JIS-standard round-body design is also shorter than an ISO 6432 cylinder, saving mounting length.
