Airtac MF32-40 Stainless Steel Mini Cylinder MF40X250CA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X250CA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 250mm 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 MF40X250CA
Generating up to 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder tackles heavy-duty positioning tasks. 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 long service life. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches.
For the same 40 mm bore and 250 mm stroke, the MF body is notably shorter than a typical ISO 6432 cylinder, saving valuable mounting length in tight fixtures. Equipped with a 1/4" air port and an M14x1.5 male rod thread, it uses fixed TPU bumper pads to soften stroke-end impact. Plan for a safe working load of about 377 N, which lets you lift roughly 32 kg vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X250CA Is Used
Press Tool Ejection
Uses the 527.8 N pull force at 0.5 MPa to extract heavy stamped parts from a die, while the CA pivot accommodates slight mechanical misalignment.
Pallet Diversion
Pushes loaded pallets sideways onto a secondary line, leveraging the 628.3 N push force to overcome sliding friction without stalling.
Heavy Crate Lift Gate
Raises 30 kg industrial crates via a pivoting gate mechanism, staying safely within the calculated 32 kg vertical lift capacity.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X250CA the Right Cylinder?
When sizing this 40 mm bore unit against the MF32, you jump from 402.2 N to 628.3 N of push force at 0.5 MPa; as 40 mm is the largest available MF bore, moving higher requires a different cylinder family. The included CA pivot back cover suits articulated rod-end loads, and you can pair the body with LB foot, FA flange, or TC trunnion mounts. At 250 mm of travel, minimize side-loading to prevent rod bending and premature seal wear.
Remember that a standard double-acting cylinder drifts if air pressure drops or the valve is centered, as the fixed bumpers only decelerate the stroke end rather than locking the piston. To suspend a load safely during an air loss event, 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 MF40X250CA FAQ
This 40 mm bore cylinder features a 1/4" air port and an M14x1.5 male rod thread. At 0.5 MPa it generates 628.3 N of push force and 527.8 N of pull force. At 0.7 MPa the push increases to 879.6 N and the pull to 738.9 N, with a theoretical maximum of 128.1 kgf at 1.0 MPa.
No, because this specific SKU does not include the -S magnet option, it cannot accept CMSG, DMSG, or EMSG reed switches. You would need the -S variant for sensing. The unit features a CA pivot back cover and fixed TPU bumper pads that decelerate the stroke end, but it is shorter than an ISO 6432 cylinder for the same bore and stroke.
