Airtac MF32-40 Stainless Steel Mini Cylinder MF40X300CA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X300CA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 300mm 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 MF40X300CA
Generating 628.3 N of push force at 0.5 MPa, this 40 mm bore double-acting mini cylinder handles heavy-duty positioning tasks. The JIS-standard round-body construction is physically shorter than a comparable ISO 6432 unit, saving valuable mounting length in tight machinery. Its SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown environments. For practical sizing, plan for around 377 N of actual work at 0.5 MPa, which safely lifts about 32 kg vertically with a 2:1 margin.
The piston relies on a heterogeneous two-way seal that retains an oil film for long service life, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts. This specific SKU lacks a magnet, meaning it cannot accept CMSG, DMSG, or EMSG sensors without switching to the -S variant. Air connects via a 1/4" port, and the included CA back cover provides a rear pivot point for angular alignment.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X300CA Is Used
Press Tool Ejection
Provides the 628.3 N push force needed to eject heavy stamped parts from a hydraulic press bed over a 300 mm travel distance.
Pallet Diverter Gate
Utilizes the CA pivot mount to swing a heavy diverter gate on a packaging conveyor, reliably redirecting filled cartons.
Material Lift Lowering
Lowers stacked metal blanks into a machining fixture, using the 300 mm stroke to clear the work zone for robotic loading.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X300CA the Right Cylinder?
When sizing this 40 mm bore, step down to the MF32 if your application only requires 402.2 N of push at 0.5 MPa, as 40 mm is the largest available bore in the MF series. For the 300 mm stroke, ensure your mounting arrangement minimizes side-load to prevent rod bending. The CA pivot back cover accommodates articulating loads, and you can pair it with LB foot, FA flange, or TC trunnion mounts.
Because this is a standard double-acting cylinder, the piston will drift if air pressure drops or the valve is centred. The TPU bumpers only decelerate the stroke end and do not function as a brake. To maintain vertical position 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 MF40X300CA FAQ
This 40 mm bore cylinder features a 1/4" 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 CMSG, DMSG, or EMSG switches will not function on it. You must select the -S variant to enable magnetic sensing. The unit features a SUS304 stainless barrel and fixed TPU bumper pads rather than an adjustable air cushion.
