Airtac MF32-40 Stainless Steel Mini Cylinder MF40X115CA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X115CA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 115mm 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 MF40X115CA
Delivering 628.3 N of push force at 0.5 MPa, this 40 mm bore double-acting actuator is built for substantial work. Its JIS-standard round-body design is physically shorter than a comparable ISO 6432 cylinder, saving valuable mounting length in tight machinery. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown environments.
Because this specific SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG position switches. 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 soften stroke-end impacts. Plan for a safe working load of about 377 N, which comfortably lifts a 32 kg part vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X115CA Is Used
Pivoting Parts Ejection
Leverages the CA pivot back cover to swing heavy stamped metal parts out of a hydraulic press bed, using the 628.3 N push force to clear the die area reliably.
Packaging Line Diverter
Pushes heavy corrugated cartons onto a secondary packaging track at high speed, benefiting from the short JIS body length to fit within tight conveyor side-frame clearances.
Pallet Component Placement
Indexes dense 30 kg automotive sub-assemblies onto outbound pallets, safely operating within the calculated 32 kg vertical lift capacity at 0.5 MPa.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X115CA the Right Cylinder?
When sizing this 40 mm bore unit, compare it directly against the smaller MF32, which provides 402.2 N of push force at 0.5 MPa. Since 40 mm is the largest available bore in the MF series, moving heavier loads requires running multiple cylinders in parallel rather than stepping up a size. The integrated CA pivot back cover makes it ideal for pivoting mechanisms, pairing seamlessly with FA flanges or TC trunnions depending on your frame.
Remember that the fixed TPU bumpers only decelerate the piston near the stroke end; they do not function as an adjustable air cushion like the MFC variant. Furthermore, if air pressure drops, a standard cylinder drifts and cannot hold a suspended load, so you must add an external rod lock or pilot-operated check valve for vertical safety. The 1/4" port and M14x1.5 male rod thread provide the high airflow and robust mechanical connection needed for this force class.
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 MF40X115CA FAQ
This 40 mm bore cylinder features a 1/4" air port and an M14x1.5 male rod thread. At 0.5 MPa it pushes with 628.3 N and pulls with 527.8 N. At 0.7 MPa the push increases to 879.6 N and pull to 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
No, this specific SKU does not include the internal magnet required for sensing. To use CMSG, DMSG, or EMSG switches, you must purchase the -S variant of the MF series. Additionally, its JIS-standard riveted stainless body is shorter than an ISO 6432 cylinder, and the CA back cover provides a rear pivot mount.
