Airtac MF32-40 Stainless Steel Mini Cylinder MF40X80SUTC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X80SUTC is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 80mm 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 MF40X80SUTC
Delivering 628.3 N of push force at 0.5 MPa, the AirTAC MF40X80SUTC is a robust 40 mm bore double-acting JIS-standard round-body mini cylinder. Because its SUS304 stainless barrel and riveted aluminium covers form a shorter envelope than an ISO 6432 cylinder of identical bore and stroke, it drops right into tight machine fixtures. The structure pairs fixed TPU bumper pads with a front-cover anti-impact pad to soften stroke-end impact.
For practical sizing, plan for about 377 N of real work at 0.5 MPa, which safely lifts roughly 32 kg vertically with a 2:1 margin. The heterogeneous two-way piston seal retains an oil film for long service life. This specific SKU includes a piston magnet for position sensing and ships with a U flat-end back cover and TC trunnion mounting. Air connects via the 1/4" port.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X80SUTC Is Used
Pallet Diverter Gate
Uses the 628.3 N thrust at 0.5 MPa to shove heavy timber pallets onto a secondary packaging line, while the TC trunnion absorbs lateral pivot stress.
Stamping Press Feed
Pushes aluminium blanks into a forming die, relying on the fixed TPU bumper pads to absorb the 80 mm stroke impact without requiring an adjustable cushion.
Vertical Parts Lift
Lifts 32 kg hardware totes vertically with a safe 2:1 margin, using the integrated magnet to trigger an EMSG sensor at the top of the stroke.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X80SUTC the Right Cylinder?
When sizing this 40 mm bore, the smaller MF32 yields 402.2 N of push at 0.5 MPa, making it a lighter alternative if your load permits. Since 40 mm is the largest available MF bore, exceeding this thrust capacity requires moving to a different cylinder family entirely. The built-in magnet allows CMSG, DMSG, or EMSG switches to track position precisely along the 80 mm stroke.
The included TC trunnion mount and U flat-end back cover suit pivoting or rigid frame installations. Remember that a standard cylinder drifts if air pressure drops or the valve centres; the TPU bumpers only decelerate the stroke end and do not function as a locking brake. To suspend a load safely during an outage, install an external rod lock or a pilot-operated check valve.
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 MF40X80SUTC FAQ
This 40 mm bore double-acting cylinder uses a 1/4" air port and an M14x1.5 male rod thread. It 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 features a SUS304 stainless steel barrel with riveted aluminium covers, making the body shorter than an ISO 6432 cylinder for the same 40x80 dimensions. This unit includes a U flat-end back cover and a TC trunnion mount. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors.
