Airtac MF32-40 Stainless Steel Mini Cylinder MF32X20SCA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X20SCA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 20mm 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 MF32X20SCA
Generating 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore cylinder is built around a SUS304 stainless steel barrel with riveted aluminium covers. The rolling-packed structure yields a shorter overall body than an ISO 6432 unit of the identical bore and stroke, yielding a tangible packaging advantage in dense machinery. A heterogeneous two-way seal retains an oil film for long life, while fixed TPU bumper pads soften the stroke-end impact.
Equipped with a piston magnet for position sensing, this unit accepts CMSG, DMSG, or EMSG switches. Plan for roughly 241 N of actual work at 0.5 MPa to ensure reliable operation, which translates to lifting about 20.5 kg vertically with a 2:1 safety margin. The 1/4" port and 20 mm stroke provide rapid, high-force clamping, and the rear CA pivot simplifies angular mounting.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X20SCA Is Used
Short-Stroke Stamping
Applies 402.2 N of clamping force at 0.5 MPa to hold thin sheet metal firmly in place during a progressive die stamping operation.
Package Diverting
Uses the 20 mm stroke and rear CA pivot to rapidly extend a diverter arm, pushing light cartons between adjacent conveyor belts.
Pallet Stopper Gate
Acts as a high-force pneumatic stop gate on a roller conveyor, halting loaded pallets before they reach the wrapping station.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X20SCA the Right Cylinder?
When sizing this 32 mm bore, dropping down to an MF25 reduces the push force to 245.3 N at 0.5 MPa, whereas stepping up to an MF40 increases it to 628.3 N. Because the 20 mm stroke is quite short, side-load and rod-bending stresses are minimal, but you should still align the load precisely to avoid premature seal wear. The included -S magnet enables direct mounting of CMSG, DMSG, or EMSG sensors.
The standard MF cylinder will drift and cannot hold a load if air pressure drops or the valve is centred; the TPU pads only decelerate the end of travel and do not act as a brake. If your application requires vertical position holding, install an external rod lock or a pilot-operated check valve. The CA rear pivot cover is ideal for applications requiring articulation.
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 MF32X20SCA FAQ
At 0.5 MPa it provides 402.2 N push and 345.6 N pull. At 0.7 MPa it yields 563 N push and 483.8 N pull. The theoretical maximum force is 82 kgf at 1.0 MPa. The air port size is 1/4".
No, the MF series is JIS-standard, not ISO 6432 compliant. However, for the same 32 mm bore and 20 mm stroke, the MF body is physically shorter than an ISO 6432 cylinder, saving mounting length. It features a SUS304 stainless barrel and fixed TPU bumper pads rather than an adjustable air cushion.
