Airtac MF32-40 Stainless Steel Mini Cylinder MF40X40CA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X40CA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 40mm 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 MF40X40CA
Generating 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore mini cylinder handles heavy-duty positioning within tight machine envelopes. The SUS304 stainless-steel barrel and riveted aluminium covers shrug off mild washdown, while the internal two-way seal retains an oil film for extended cycle life. A practical choice for high-cycle automation, it provides about 377 N of safe working load and lifts roughly 32 kg vertically with a 2:1 margin.
For the same bore and stroke, the JIS-standard round body is noticeably shorter than a comparable ISO 6432 unit, saving valuable mounting length. This specific CA-pivot configuration features a rear clevis for articulated mounting, a 1/4" port, and fixed TPU bumper pads that soften stroke-end impact. Note that this SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG position switches without upgrading to the -S variant.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X40CA Is Used
Stamping Press Ejection
Uses the robust 628.3 N push force to knock heavy stamped metal parts out of a die, where the short 40 mm stroke and compact JIS body fit neatly between press columns.
Pallet Diverter Arm
Leverages the CA pivot mount to swing a heavy diverter arm on a packaging line, reliably routing dense pallets laterally without overwhelming the 40 mm bore capacity.
Heavy Carton Lid Flap
Closes thick cardboard flaps on industrial shipping cartons, utilizing the 527.8 N pull force and fixed TPU bumpers to absorb the repetitive impact of high-speed case sealing.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X40CA the Right Cylinder?
When sizing this 40 mm bore, compare its 628.3 N @0.5 MPa output against the smaller MF32, which yields 402.2 N; since 40 mm is the largest available MF bore, moving beyond this capacity requires a different cylinder family. The CA rear pivot cover is ideal for applications requiring angular alignment, and you can pair it with FA flanges or LB foot mounts if rigid fixing is preferred. Because the stroke is a short 40 mm, rod-bending side loads are minimal, but ensure external guides carry any heavy lateral weight.
Remember that the fixed TPU bumpers only decelerate the piston near the stroke end; they do not function as a brake. If air pressure drops or the directional valve is centred, the rod will drift and drop the load. To prevent vertical sinking, integrate an external pilot-operated check valve or a dedicated rod lock 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 MF40X40CA 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, 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 a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You must select the -S variant (MF40X40CA-S) for position sensing. Additionally, its JIS-standard riveted round body is shorter than an ISO 6432 cylinder, saving mounting space.
