Airtac MF32-40 Stainless Steel Mini Cylinder MF40X700CA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X700CA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 700mm 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 MF40X700CA
Generating 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore mini cylinder handles heavy-duty positioning tasks. The 700 mm stroke is a made-to-order length exceeding the 500 mm standard maximum, built specifically for long-reach applications. Its SUS304 stainless round barrel and riveted aluminium covers form a compact JIS-standard body that is physically shorter than an ISO 6432 cylinder of the same bore and stroke, saving valuable mounting space. The piston relies on a two-way oil-retaining seal for long life, while fixed TPU pads decelerate the stroke ends.
Because the rod must travel 700 mm, plan for a safe working load of roughly 377 N, which is about 60 percent of the 0.5 MPa push rating, to account for friction and side loads. For vertical lifting, this translates to hoisting about 32 kg safely with a 2:1 margin. This SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors without switching to the -S variant. Air connects via a 1/4" port, and the rear CA pivot cover accommodates articulating rod-end loads.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X700CA Is Used
Long-Reach Diverting
Pushes heavy pallets across a 700 mm transfer gap using the full 628.3 N thrust at 0.5 MPa, with the CA pivot absorbing minor misalignment.
Vertical Hoist Assembly
Lifts 32 kg chassis components vertically between conveyor tiers, taking advantage of the calculated 2:1 safety margin on the 40 mm bore.
Washdown Ejection
Ejects machined aluminium parts from a coolant bath, leveraging the SUS304 stainless barrel to resist mild corrosion and moisture exposure.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X700CA the Right Cylinder?
When sizing this actuator, compare its 628.3 N push force at 0.5 MPa against the neighbouring bores. If your fixture is lighter, stepping down to the 32 mm bore drops the output to 402.2 N, which may suffice and save space. Since 40 mm is the largest available MF bore, exceeding this capacity requires moving to an entirely different cylinder family. The 700 mm stroke is non-standard and made-to-order; at this length, preventing rod bending is critical, so ensure rigid guidance on the payload to avoid destructive side-loading.
The included CA rear pivot cover is ideal for applications requiring angular alignment compensation. Note that this specific SKU has no internal magnet, meaning position sensing is impossible unless you specify an -S model. Furthermore, standard bumpers only soften the end-of-stroke impact; they will not hold a load vertically if air pressure drops. To prevent drifting, integrate an external pilot 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 MF40X700CA FAQ
This 40 mm bore double-acting cylinder uses 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 lacks an internal piston magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You must select the -S variant for sensing capabilities. Additionally, its JIS-standard riveted body is shorter than a comparable ISO 6432 cylinder, and the fixed TPU bumpers only decelerate the stroke end rather than holding the load.
