Airtac MF32-40 Stainless Steel Mini Cylinder MF40X100SCMTC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X100SCMTC is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 100mm 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 MF40X100SCMTC
Delivering 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore AirTAC MF cylinder tackles heavier automation tasks within a compact footprint. Because the JIS-standard riveted round-body is physically shorter than an ISO 6432 cylinder of the exact same bore and stroke, it saves valuable mounting length in tight machinery. The SUS304 stainless steel barrel pairs with aluminium covers to resist mild corrosion and washdown, while the piston's two-way seal retains an oil film for extended mechanical life.
This specific configuration includes a built-in piston magnet for CMSG, DMSG, or EMSG switches, a CM round-end back cover, and a TC trunnion mount. Instead of an adjustable air cushion, fixed TPU bumper pads and a front-cover anti-impact pad absorb the stroke-end shock. For practical sizing, plan for a safe working load of roughly 377 N, which easily lifts about 32 kg vertically with a 2:1 safety margin. Air connects via a 1/4" port, and the 16 mm rod features an M14x1.5 male thread.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X100SCMTC Is Used
Stamping Pin Ejection
Uses the 628.3 N push force at 0.5 MPa to eject stamped metal pins from a die block reliably without requiring high-pressure air.
Heavy Package Diversion
Swings a pivoting diverter arm via the TC trunnion mount to push heavier cartons off a main conveyor line into a packing lane.
Pallet Stop Gate
Acts as a robust stop gate on a roller conveyor, holding pallets steady while the CM round-end cover and bumper pads absorb the impact.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X100SCMTC the Right Cylinder?
When sizing this 40 mm bore, stepping down to an MF32 provides 402.2 N of push force at 0.5 MPa, whereas this MF40 is the largest available in the series, offering a theoretical maximum of 128.1 kgf at 1.0 MPa. The integrated TC trunnion and CM round-end rear cover suit pivoting articulations, and the -S magnet allows direct sensor mounting. Keep in mind that a standard cylinder drifts if air pressure drops or the valve centres; the TPU bumpers only soften the end-of-stroke impact rather than locking the rod. To suspend a load safely mid-stroke, fit an external rod lock or a pilot-operated check valve. At a 100 mm stroke, side loading is minimal, but always ensure the trunnion mounts align with the load vector to prevent rod bending.
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 MF40X100SCMTC FAQ
This 40 mm bore double-acting cylinder pushes with 628.3 N and pulls with 527.8 N at 0.5 MPa. At 0.7 MPa, push increases to 879.6 N and pull to 738.9 N, with a theoretical maximum of 128.1 kgf at 1.0 MPa. It uses a 1/4" air port and a 16 mm rod with an M14x1.5 male thread.
The MF is a JIS-standard round-body cylinder that is physically shorter than an ISO 6432 model for the same 40 mm bore and 100 mm stroke, saving mounting length. Because this SKU includes the -S magnet, it directly accepts CMSG, DMSG, or EMSG switches for position detection.
