Airtac MF32-40 Stainless Steel Mini Cylinder MF40X450CA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X450CA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 450mm 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 MF40X450CA
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy-duty positioning tasks. The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown, while the internal two-way seal retains an oil film for prolonged operational life. Because the MF body is shorter than a comparable ISO 6432 cylinder for the same 450 mm stroke, it saves valuable mounting length in tight machinery.
Equipped with fixed TPU bumper pads and a front-cover anti-impact pad, the stroke end is reliably decelerated without the need for adjustable cushioning. Plan for a safe working load of about 377 N, which is roughly 60 percent of the 0.5 MPa push rating, to account for friction and dynamics. Alternatively, it can vertically lift about 32 kg with a 2:1 safety margin. This specific SKU lacks a magnet and therefore cannot accept CMSG, DMSG, or EMSG position switches. The 1/4 inch port and M14x1.5 male rod thread accommodate robust pneumatic flow and heavy mounting fixtures.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X450CA Is Used
Pallet Divertor
Uses the 628.3 N push force at 0.5 MPa to deflect heavy timber pallets onto secondary packaging lines without stalling.
Vertical Gate Actuator
Lifts a 32 kg security gate panel through a 450 mm stroke, utilising the CA pivot to accommodate slight angular shifts.
Stamping Ejector
Ejects dense aluminium castings from a hydraulic press bed, relying on the SUS304 barrel to withstand coolant spray.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X450CA the Right Cylinder?
When sizing this 40 mm bore unit, verify your actual force requirements against the available range. If your application demands less thrust, stepping down to the MF32 provides 402.2 N of push force at 0.5 MPa, whereas the MF40 is the largest available bore in this series, so higher loads require an entirely different cylinder family. The integrated CA pivot back cover simplifies rear clevis mounting for angular movement, and you can pair the body with LB foot, FA flange, or TC trunnion brackets depending on the frame geometry. Because this 450 mm stroke approaches the standard limit, ensure your guiding structure prevents rod bending and side loads.
Remember that a standard double-acting cylinder relies entirely on continuous air pressure to maintain its position. If the air supply drops or the directional valve is centred, the piston will drift, and the fixed TPU bumpers only soften the end-of-stroke impact rather than acting as a mechanical brake. To suspend a load safely during an outage, install an external pilot-operated check valve or a dedicated rod lock.
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 MF40X450CA 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 the -S magnet option, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for internal sensing. The unit uses fixed TPU bumper pads for deceleration and features a CA pivot back cover for clevis mounting.
