Airtac MF32-40 Stainless Steel Mini Cylinder MF40X10U
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X10U is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 10mm 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 MF40X10U
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy-duty tasks in tight spaces. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown, while the two-way oil-retaining piston seal ensures long operational life. For practical sizing, plan for about 377 N of real work at 0.5 MPa, which translates to lifting roughly 32 kg vertically with a 2:1 safety margin.
This specific U variant features a flat-end back cover, making it easy to mount flush against machine frames. Because the stroke is only 10 mm, the fixed TPU bumper pads and front-cover anti-impact pad effectively absorb the end-of-travel shock without needing adjustment. Air connects via a 1/4" port, and the 16 mm rod uses an M14x1.5 male thread. Note that this SKU lacks a magnet, so it cannot accept CMSG, DMSG or EMSG position switches without upgrading to an -S version.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X10U Is Used
Short-Stroke Stamping
Provides a rapid 10 mm pressing action for crimping small metal terminals in high-speed wire harness production lines.
Heavy-Duty Clamping
Exerts up to 879.6 N of push force at 0.7 MPa to secure heavy aluminium castings firmly inside CNC machining centres.
Rigid Part Ejection
Uses the flat-end U rear cover to mount directly against a die plate, ejecting dense moulded plastic parts from tight tooling cavities.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X10U the Right Cylinder?
When sizing this actuator, compare its 628.3 N push force at 0.5 MPa against the smaller MF32 bore, which provides 402.2 N. Since 40 mm is the largest available bore in the MF family, moving beyond this capacity requires a different cylinder series entirely. The compact 10 mm stroke is perfect for short clamping motions, but always verify that your side loads stay minimal to prevent rod bending.
Keep in mind that a standard double-acting cylinder will drift if air pressure drops or the valve is centred; the TPU bumpers only soften the stroke end and act as neither a brake nor a lock. To suspend a load safely during an air loss event, integrate an external rod lock or a pilot-operated check valve into your 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 MF40X10U FAQ
This 40 mm bore cylinder features a 1/4" air port and an M14x1.5 male 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 piston magnet, so it cannot support CMSG, DMSG or EMSG switches. You would need the -S variant for sensing capabilities. Additionally, its JIS-standard body is shorter than a comparable ISO 6432 cylinder, saving valuable mounting length.
