Airtac MF32-40 Stainless Steel Mini Cylinder MF40X75U
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X75U is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 75mm 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 MF40X75U
Delivering 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore JIS-standard round-body mini cylinder handles heavy-duty actuation within a compact footprint. Because the SUS304 stainless-steel barrel and riveted aluminium covers yield a shorter overall body than an ISO 6432 cylinder of identical bore and stroke, you save valuable mounting length in dense machinery layouts. The 1/4 inch port and M14x1.5 male rod thread accommodate robust pneumatic supply and mechanical coupling.
For practical sizing, plan for roughly 377 N of real work at 0.5 MPa, which safely lifts about 32 kg vertically with a 2:1 margin. The internal two-way seal retains an oil film for long service life, while fixed TPU bumper pads and a front-cover anti-impact pad soften the stroke-end impact. Note that this specific SKU lacks a magnet, meaning it cannot accept CMSG, DMSG, or EMSG position switches without upgrading to the -S variant.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X75U Is Used
Stamping Press Ejection
Uses the 628.3 N push force at 0.5 MPa to knock stamped metal blanks out of progressive dies reliably.
Heavy Package Diversion
Leverages the 75 mm stroke and U flat-end rear cover to push heavy cartons onto secondary packaging lines.
Pallet Component Sorting
Employs the 40 mm bore power to index dense industrial components off a main palletizing conveyor track.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X75U the Right Cylinder?
When sizing this 40 mm bore unit, verify your force requirements both ways: stepping down to the MF32 provides 402.2 N at 0.5 MPa, whereas this MF40 yields 628.3 N. Since 40 mm is the largest available MF bore, any requirement exceeding this class necessitates a different cylinder family. This model features a U flat-end back cover, offering a straightforward mounting face for rear attachment.
Remember that a standard double-acting cylinder drifts if air pressure drops or the valve is centred; the TPU bumpers only decelerate the piston near the stroke end and do not function as a locking brake. To suspend a load safely mid-stroke, integrate an external pilot-operated check valve or a dedicated rod lock. Furthermore, because this SKU has no internal magnet, position sensing is impossible without sourcing the -S magnet version.
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 MF40X75U FAQ
This 40 mm bore cylinder features a 1/4 inch port and an M14x1.5 male rod thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, increasing to 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
No, this specific SKU does not include an internal magnet, so it cannot support CMSG, DMSG, or EMSG switches. You must select the -S variant for sensing capabilities. Additionally, its JIS-standard riveted stainless body is shorter than an ISO 6432 cylinder, saving mounting length.
