Airtac MF32-40 Stainless Steel Mini Cylinder MF32X225CM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X225CM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 225mm 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 MF32X225CM
Delivering 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles substantial work within a compact footprint. For the same 32 mm bore and 225 mm stroke, the MF body is physically shorter than an ISO 6432 cylinder, saving valuable mounting length in tight machinery. The SUS304 stainless steel barrel and riveted rolling-packed aluminium covers resist mild corrosion and washdown environments.
The piston relies on a heterogeneous two-way seal that retains an oil film for prolonged lifespan, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts. Plan for roughly 241 N of actual work at 0.5 MPa, which means it can safely lift about 20.5 kg vertically with a 2:1 safety margin. This specific SKU lacks a magnet and therefore cannot support CMSG, DMSG, or EMSG sensors; you would need the -S variant for position detection. It features a 1/4" port and a CM round-end rear cover.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X225CM Is Used
Package Diverting
Actuates a routing gate on a packaging line, using the 402.2 N push force to swing heavy cardboard cartons onto secondary tracks at 225 mm of travel.
Clamp Actuation
Secures aluminium extrusions in a CNC machining fixture, providing reliable holding pressure during milling operations without exceeding the 241 N safe working load.
Vertical Part Lifting
Raises 20 kg material trays between processing stations, taking advantage of the JIS compact body to fit within tight vertical elevator shafts.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X225CM the Right Cylinder?
When sizing this 32 mm bore, the adjacent MF25 provides 245.3 N at 0.5 MPa, whereas stepping up to the MF40 yields 628.3 N at 0.5 MPa, giving you clear room to adjust if your load changes. Because this is a standard SKU without an -S suffix, it cannot accept magnetic switches; if your sequence requires end-of-stroke confirmation, select the -S version instead. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion brackets to suit your frame.
At 225 mm, the stroke is well within the 500 mm standard limit, though you should still minimize side loads to prevent rod bending over the extended travel. Remember that the fixed TPU bumpers only decelerate the piston near the end of travel; they do not function as a brake. If air pressure drops or the valve is centred, the piston will drift, so fit an external rod lock or a pilot-operated check valve for suspended loads.
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 MF32X225CM FAQ
This 32 mm bore cylinder features a 1/4" port and an M10x1.25 male rod thread. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum force of 82 kgf at 1.0 MPa.
It does not conform to ISO 6432, though its JIS round-body design is intentionally shorter than an ISO 6432 cylinder to save mounting space. This SKU lacks a magnet for sensors, but you can use LB, FA, SDB, or TC mounts, and the CM round-end back cover allows direct pivot mounting.
