Airtac MF32-40 Stainless Steel Mini Cylinder MF40X10SU
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X10SU 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 MF40X10SU
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 barrel and riveted aluminium covers resist mild corrosion and washdown, while the piston's two-way seal retains an oil film for extended lifespan. For the same 40 mm bore and 10 mm stroke, the MF body is notably shorter than an ISO 6432 cylinder, delivering a real packaging win.
Equipped with a built-in magnet, the unit supports CMSG, DMSG, and EMSG position sensing. It features a 1/4" port, an M14x1.5 male rod thread, and a flat-end U back cover. Plan for roughly 377 N of actual work at 0.5 MPa, which means it can safely lift about 32 kg vertically against gravity.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X10SU Is Used
Heavy-Duty Stamping Clamp
Provides 628.3 N of secure holding force at 0.5 MPa to lock thick steel plates in place during aggressive pneumatic stamping operations.
Pallet Diverting Gate
Uses the 10 mm stroke to rapidly pop up a guiding gate, deflecting heavy loaded pallets between packaging lanes without taking up frame length.
Forklift Carriage Stop
Acts as a rigid physical stopper on automated guided vehicle carriages, utilizing the flat-end U back cover to absorb harsh mechanical impacts safely.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X10SU the Right Cylinder?
When sizing this 40 mm bore actuator, compare its 628.3 N push force at 0.5 MPa against the smaller MF32, which outputs 402.2 N. Since 40 mm is the largest available MF bore, moving higher requires an entirely different cylinder family. The fixed TPU bumper pads and front-cover anti-impact pad soften stroke-end impact, but they only decelerate; they do not act as a brake.
If your process drops air or the valve centres, the piston will drift and drop the load. To maintain vertical position, install an external rod lock or a pilot-operated check valve. For high-cycle automated machinery needing adjustable end-cushioning, consider the MFC variant instead of this standard bumper model.
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 MF40X10SU FAQ
This 40 mm bore cylinder features a 1/4" port and an M14x1.5 male rod thread. At 0.5 MPa it pushes with 628.3 N and pulls with 527.8 N. At 0.7 MPa, push increases to 879.6 N and pull to 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in piston magnet designed specifically for CMSG, DMSG, and EMSG electronic or reed switches. Additionally, for the same 40 mm bore and 10 mm stroke, this JIS-standard actuator features a shorter body than an ISO 6432 cylinder, saving valuable mounting space.
