Airtac MF32-40 Stainless Steel Mini Cylinder MF32X400CA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X400CA 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 MF32X400CA
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore JIS-standard round-body mini cylinder is built for demanding fixture automation. Its SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown environments, while the two-way piston seal retains an oil film for extended mechanical life. Because the MF body is shorter than an ISO 6432 cylinder for the same 400 mm stroke, it saves valuable mounting length in tight machinery.
Equipped with a CA pivot back cover, this model uses fixed TPU bumper pads and a front-cover anti-impact pad to soften stroke-end impact, though these decelerate rather than provide adjustable cushioning. Lacking the -S suffix, this specific SKU cannot accept magnetic CMSG, DMSG, or EMSG switches. For practical actuation at 0.5 MPa, plan for roughly 241 N of real work, which translates to lifting about 20.5 kg vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X400CA Is Used
Pallet Diversion Gate
Swings a pivot-mounted diverter arm along a packaging line to route 20 kg product pallets, utilising the 400 mm stroke and CA pivot cover for smooth lateral transfer.
Textile Beam Indexing
Pushes heavy fabric beams forward into the loading cradle of a weaving machine, where the compact JIS body length prevents interference with adjacent spinning frames.
Vertical Parts Lift
Raises stacked metal baskets 400 mm within an assembly cell, comfortably handling the 20.5 kg vertical lift capacity calculated at a 2:1 safety margin.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X400CA the Right Cylinder?
When sizing this 32 mm bore actuator, compare it directly with its neighbours: the MF25 provides 245.3 N at 0.5 MPa if your load is lighter, while the MF40 steps up to 628.3 N for heavier demands. This 400 mm stroke is well within the 500 mm standard limit, but at this extended length you must carefully manage side loads to prevent rod bending and premature seal wear. The 1/4" port matches the bore size for adequate flow.
Remember that a standard double-acting cylinder like this relies entirely on continuous air pressure to maintain its position. If air is lost or the valve is centred, the piston will drift; the TPU bumpers only absorb end-of-stroke impact and do not act as a braking mechanism. To suspend a load safely during an emergency stop or air loss, 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 MF32X400CA FAQ
This 32 mm bore cylinder features a 1/4" port and an M10x1.25 male rod thread. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum force of 82 kgf at 1.0 MPa.
No, because this SKU lacks the -S suffix, it does not have an internal magnet and cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for magnetic sensing, though the CA pivot back cover remains available for mechanical mounting.
