Airtac MF32-40 Stainless Steel Mini Cylinder MF40X100SCATC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X100SCATC 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 MF40X100SCATC
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy-duty automation within a compact footprint. Because the SUS304 stainless steel barrel and riveted aluminium covers form a shorter overall body than an equivalent ISO 6432 unit, you save valuable mounting length in tight machinery. The 1/4 inch port feeds the 16 mm piston rod, while fixed TPU bumper pads and a front-cover anti-impact pad absorb stroke-end shock.
The heterogeneous two-way seal retains an oil film for extended mechanical life. Plan for roughly 377 N of actual work at 0.5 MPa, which safely lifts about 32 kg vertically with a 2:1 margin. The integrated -S magnet allows CMSG, DMSG, or EMSG switches for position sensing, and the CA pivot back cover pairs with the TC trunnion mount for articulated loads.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X100SCATC Is Used
Stamping Press Feed
Pushes heavy metal blanks into a progressive die using the full 628.3 N output, relying on the TC trunnion to accommodate frame misalignment.
Pallet Diverting
Sweeps loaded pallets sideways at sorting stations, where the SUS304 stainless barrel withstands intermittent washdowns.
Vertical Gate Lifting
Raises 30 kg security gates on packaging lines, staying safely within the 32 kg vertical lift capacity at 0.5 MPa.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X100SCATC the Right Cylinder?
When sizing this 40 mm bore, compare its 628.3 N push force at 0.5 MPa against the smaller MF32, which yields 402.2 N. Since 40 mm is the largest available MF bore, exceeding this capacity requires a different cylinder family. The TC trunnion and CA pivot combination suits pivoting articulation, though you must support side loads to prevent rod bending.
Remember that the fixed TPU bumpers only soften the end-of-stroke impact; they do not function as a brake. If air pressure drops or the valve is centred, the piston will drift, so install an external rod lock or pilot-operated check valve to suspend loads securely.
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 MF40X100SCATC FAQ
This 40 mm bore cylinder features a 1/4 inch air port and an M14x1.5 male rod thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum force of 128.1 kgf at 1.0 MPa.
No, the fixed TPU bumper pads only decelerate the piston near the stroke end and act as a brake. The piston drifts if air is lost or the valve is centred, requiring an external rod lock or pilot check valve to hold loads. The -S magnet supports CMSG/DMSG/EMSG sensors.
