Airtac MF32-40 Stainless Steel Mini Cylinder MF40X500U
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X500U is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 500mm 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 MF40X500U
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles substantial loads across its 500 mm travel. The SUS304 stainless-steel barrel and riveted aluminium covers resist mild corrosion and washdown, while the internal two-way seal retains an oil film for extended mechanical life. Because the MF body is shorter than a comparable ISO 6432 unit for the same bore and stroke, it saves valuable mounting length on long-stroke machinery.
For practical sizing, plan for roughly 377 N of real work at 0.5 MPa, which safely lifts about 32 kg vertically with a 2:1 margin. The stroke end is softened by fixed TPU bumper pads and a front-cover anti-impact pad. Note that this specific SKU lacks a magnet and cannot host CMSG, DMSG, or EMSG switches; order an -S variant if position sensing is required. It features a 1/4" port and an M14x1.5 male rod thread.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X500U Is Used
Carton Push-off Diverter
Uses the full 500 mm stroke and 628.3 N thrust to push heavy cardboard cartons from a main packaging conveyor onto a secondary sorting belt.
Pallet Component Staging
Extends fully to push dense metal fixtures or bearing housings into a palletizing station, taking advantage of the U flat-end rear cover for stable vertical mounting.
Textile Beam Transfer
Shifts heavy textile warp beams horizontally between processing machines, where the SUS304 stainless barrel withstands humid lint-filled environments.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X500U the Right Cylinder?
When sizing this 40 mm bore, step down to the MF32 if your application only requires 402.2 N of push force at 0.5 MPa, as the smaller bore saves air volume. Since 40 mm is the largest available MF bore, exceeding this thrust capacity means you must bundle multiple cylinders or switch to a larger series entirely. This model features a U flat-end back cover, making it easy to mount directly to a flat surface.
At 500 mm of travel, side loads become a critical factor; ensure your load is guided to prevent rod bending and premature seal wear. Furthermore, a standard cylinder drifts when air is lost or the valve is centred, as the bumpers only decelerate the stroke end rather than locking the piston. To suspend a load safely mid-stroke, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 MF40X500U FAQ
The 40 mm bore 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. It uses a 1/4" air port and an M14x1.5 male rod thread.
No, this specific SKU does not include a magnet, so it cannot host CMSG, DMSG, or EMSG switches. You must order the -S variant for position sensing. The unit features a JIS-standard riveted round body that is physically shorter than an ISO 6432 cylinder, saving mounting length on long 500 mm strokes.
