Airtac MF32-40 Stainless Steel Mini Cylinder MF32X225SU
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X225SU 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 MF32X225SU
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. The SUS304 stainless steel barrel and riveted rolling-packed aluminium covers resist mild corrosion and washdown environments. A heterogeneous two-way seal retains an oil film for long piston life, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts.
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 built-in magnet (-S) supports CMSG, DMSG, and EMSG sensors for position detection. Plan for roughly 241 N of actual work at 0.5 MPa, which safely lifts about 20.5 kg vertically with a 2:1 margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X225SU Is Used
Package Diverting
Pushes medium-weight cartons off a sorting line using 402.2 N of thrust at 0.5 MPa, fitting neatly into tight transfer gaps.
Clamp Actuation
Secures aluminium extrusions during CNC milling, where the 225 mm stroke provides ample reach for varying part widths.
Vertical Lifting
Elevates 20 kg product totes between conveyor tiers, relying on the built-in magnet to confirm the fully raised position.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X225SU the Right Cylinder?
When sizing this 32 mm bore, stepping down to the MF25 yields 245.3 N at 0.5 MPa, whereas moving up to the MF40 provides 628.3 N. This model includes the U flat-end back cover and a 1/4 inch port. Because this is a double-acting cylinder, air drives both directions; the TPU pads only decelerate the stroke end and do not act as a lock. If your application must hold a vertical load when air is lost or the valve is centred, add an external rod lock or a pilot-operated check valve to prevent drifting. At 225 mm, verify your mounting to avoid rod bending under side 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 MF32X225SU FAQ
This 32 mm bore cylinder features a 1/4 inch port and a 12 mm rod. 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.
The MF is a JIS-standard round-body cylinder, not an ISO 6432 compliant unit, though its riveted stainless build is shorter than an ISO 6432 model for the same stroke. The included -S magnet allows CMSG, DMSG, or EMSG switches, and the rear U flat-end cover supports various mounting brackets.
