Airtac MF32-40 Stainless Steel Mini Cylinder MF40X10SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X10SCM 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 MF40X10SCM
Generating 628.3 N of push force at 0.5 MPa, this 40 mm bore double-acting mini cylinder handles heavy short-stroke clamping with ease. The JIS-standard round-body design is physically shorter than a comparable ISO 6432 unit, saving valuable mounting length in tight machine fixtures. It features a SUS304 stainless-steel barrel with riveted aluminium covers that resist mild corrosion and washdown environments. The piston relies on a two-way oil-retaining seal for long service life.
Equipped with a built-in piston magnet (-S), it supports CMSG, DMSG, and EMSG position switches. Fixed TPU bumper pads and a front-cover anti-impact pad soften the stroke-end impact without acting as an adjustable cushion. For real-world sizing, plan for a safe working load of about 377 N (roughly 60% of the 0.5 MPa rating), which means it can safely lift a 32 kg part vertically with a 2:1 safety margin. The unit includes a CM round-end rear cover and uses a 1/4" port.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X10SCM Is Used
Heavy-Duty Stamping Clamp
Secures thick steel plates in a stamping press, using the 628.3 N push force to prevent workpiece shift during high-impact operations.
Pneumatic Riveting Anvil
Provides a rigid 10 mm stroke bottoming force for a riveting head, absorbing end-impact through fixed TPU pads to protect the frame.
Pallet Stopper Gate
Acts as a heavy stop block on a conveyor line, deploying the 16 mm rod to halt loaded pallets before a packaging station.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X10SCM the Right Cylinder?
When sizing this actuator, compare its 628.3 N push force at 0.5 MPa against the smaller MF32, which provides 402.2 N. Since 40 mm is the largest available MF bore, you cannot step up within this series; exceeding 128.1 kgf at 1.0 MPa requires a different cylinder family. The 10 mm stroke is extremely short, so side-load risks from rod bending are minimal, but ensure the CM round-end rear cover matches your pivot mounting geometry.
This SKU includes the -S magnet for CMSG, DMSG, or EMSG sensors. Remember that a standard cylinder drifts if air pressure drops or the valve is centred; the TPU bumpers only decelerate the stroke end and will not lock the load. To prevent dropping, 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 MF40X10SCM FAQ
At 0.5 MPa, the push force is 628.3 N and the pull force is 527.8 N. 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. This 40 mm bore cylinder uses a 1/4" air port and an M14x1.5 male rod thread.
No, it does not conform to ISO 6432, though its JIS-standard round body is deliberately shorter than an ISO 6432 cylinder to save space. It uses fixed TPU bumper pads for end-deceleration, not an adjustable air cushion (which requires the MFC variant). The -S magnet allows CMSG, DMSG, and EMSG switches, and the CM back cover provides a round-end pivot point.
