Airtac MF32-40 Stainless Steel Mini Cylinder MF32X200U
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X200U is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 200mm 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 MF32X200U
Generating 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder integrates a SUS304 stainless barrel with riveted aluminium covers to handle mild washdowns. The 1/4 inch port and 200 mm stroke make it highly versatile for mid-range automation. Because the MF body is shorter than an ISO 6432 cylinder for the same envelope, it drops into tighter fixtures without sacrificing travel.
The internal piston relies on a heterogeneous two-way seal that retains an oil film for long-term friction reduction, while fixed TPU bumper pads and a front-cover anti-impact pad absorb stroke-end shock. Plan for roughly 241 N of actual work at 0.5 MPa to maintain reliability, which translates to lifting about 20.5 kg vertically with a 2:1 safety margin. This specific U-style unit features a flat-end back cover and lacks the S suffix, meaning it cannot host CMSG, DMSG, or EMSG magnetic switches.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X200U Is Used
Carton Diverting Gate
Pushes corrugated packaging cartons laterally across a packaging conveyor belt using its 200 mm travel and 402.2 N thrust at 0.5 MPa.
CNC Lathe Door Actuator
Opens and closes the sliding safety door on a CNC turning center, utilizing the compact JIS body length to fit within strict machine guards.
Parts Ejector Chute
Ejects machined aluminium components from a fixture down a gravity chute, safely handling parts weighing up to the 20.5 kg vertical lift threshold.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X200U the Right Cylinder?
When sizing this 32 mm bore, verify your actual load requirements against the 402.2 N push capacity at 0.5 MPa. If your application is lighter, stepping down to the MF25 provides 245.3 N and saves physical envelope space; conversely, heavier machinery requiring more thrust should step up to the MF40, which delivers 628.3 N at the same 0.5 MPa pressure.
Keep in mind that a standard MF cylinder will drift and lose its position if air pressure drops or the valve is centred, as the TPU bumpers only decelerate the stroke end rather than locking the rod. For vertical or suspended loads that must remain fixed during air loss, you must integrate an external rod lock or a pilot-operated check valve. Furthermore, the 200 mm stroke demands careful mounting to prevent rod bending—use FA flange or TC trunnion supports to minimize side loading and preserve the bearing life.
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 MF32X200U FAQ
This 32 mm bore cylinder features a 1/4 inch air port and an M10x1.25 male rod thread. At 0.5 MPa it provides 402.2 N of push force and 345.6 N of pull force. At 0.7 MPa the push increases to 563 N and the pull to 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, because this specific SKU lacks the S suffix, it has no internal magnet and cannot support CMSG, DMSG, or EMSG switches. You would need the MF32X200US variant for sensing. Additionally, its fixed TPU bumper pads decelerate the stroke but do not act as an adjustable air cushion, and its JIS round-body design is physically shorter than a comparable ISO 6432 unit.
