Airtac MF32-40 Stainless Steel Mini Cylinder MF40X110CA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X110CA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 110mm 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 MF40X110CA
Delivering 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore mini cylinder handles heavy-duty positioning tasks. The JIS-standard round-body architecture is physically shorter than an ISO 6432 cylinder for the same 110 mm stroke, yielding a compact footprint that fits tighter machinery. Its SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments.
For practical sizing, plan your moving mass around 377 N of actual work (about 60% of the 0.5 MPa rating), which safely lifts roughly 32 kg vertically. The internal piston relies on a two-way oil-retaining seal for long life, while fixed TPU bumper pads and a front-cover anti-impact pad absorb stroke-end shock. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X110CA Is Used
Press Tool Ejection
Uses the 628.3 N push force to eject formed metal parts from a stamping die, absorbing the sudden impact via the fixed TPU bumper pads.
Pallet Diverter Arm
Actuates a heavy routing gate on a packaging line, where the SUS304 stainless barrel withstands daily washdowns and the CA pivot handles angular loads.
Vertical Lift Gate
Raises a 30 kg security gate on an automated assembly conveyor, operating safely within the 32 kg vertical lift margin at 0.5 MPa.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X110CA the Right Cylinder?
When sizing this 40 mm bore unit, verify if the smaller MF32 (providing 402.2 N push at 0.5 MPa) might suffice for lighter loads, as the MF40 is the largest available in the series. The integrated CA pivot back cover is ideal for clevis mounting, but remember that a plain double-acting cylinder drifts when air is lost or a valve is centred; the bumpers only decelerate the stroke end and will not hold a load. For vertical or suspended masses, install an external rod lock or a pilot-operated check valve. If your cycle speed demands adjustable end-cushioning, step up to the MFC variable-cushion variant instead of relying on the fixed MF bumpers.
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 MF40X110CA FAQ
At 0.5 MPa it pushes with 628.3 N and pulls with 527.8 N. At 0.7 MPa the 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, this specific SKU does not include a magnet, so it cannot host CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. It features a CA pivot back cover and is a JIS-standard round body that is shorter than an ISO 6432 cylinder, saving mounting length.
