Airtac MF32-40 Stainless Steel Mini Cylinder MF40X80UTC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X80UTC 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 MF40X80UTC
Delivering 628.3 N of push force at 0.5 MPa, this 40 mm bore double-acting mini cylinder tackles heavy-duty clamping and lifting tasks. The JIS-standard round-body design is physically shorter than a comparable ISO 6432 unit for the same 80 mm stroke, saving valuable mounting length in tight machine fixtures. It features a SUS304 stainless-steel barrel with riveted aluminium covers that resist mild corrosion and washdown environments.
The internal piston relies on a two-way oil-retaining seal to maintain lubrication for long service life, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts. Plan for roughly 377 N of actual work at 0.5 MPa to maintain a safe margin, which means it can reliably lift about 32 kg vertically. This specific configuration includes a U flat-end back cover and a TC trunnion mount. Because this SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG position switches.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X80UTC Is Used
Stamping Press Ejection
Uses the 527.8 N pull force at 0.5 MPa to positively eject heavy formed metal panels from a stamping die, preventing double-hit errors in automated press lines.
Pallet Component Indexing
Leverages the TC trunnion mount and U flat-end cover to pivot and push heavy pallet sub-assemblies along a conveyor at 80 mm per cycle.
Heavy Carton Sealing
Provides the robust 628.3 N push force required to hold large, rigid corrugated cartons firmly in place during automated top and bottom tape sealing operations.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X80UTC the Right Cylinder?
When sizing this 40 mm bore, step down to the MF32 if your task requires less than 402.2 N of push force at 0.5 MPa, as the smaller bore saves air volume and physical space. Since 40 mm is the largest available MF bore, exceeding the 879.6 N push capacity at 0.7 MPa means you will need to gang multiple cylinders or switch to a larger series entirely. The included TC trunnion mount pairs with the U flat-end rear cover to handle pivotal load requirements.
Remember that a standard double-acting cylinder drifts when air pressure drops or the directional valve is centred; the internal bumpers only decelerate the stroke end and do not function as a locking brake. To suspend a vertical load safely during an air loss event, install an external pilot-operated check valve or a dedicated rod lock. Furthermore, an 80 mm stroke at this bore class handles moderate side loads well, but always verify that your load is guided 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 MF40X80UTC FAQ
This 40 mm bore cylinder features a 1/4" air port and an M14x1.5 male rod thread. The double-acting thrust outputs are 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.
No, this specific SKU does not have a magnet and cannot accept CMSG, DMSG, or EMSG switches; you would need the -S variant for position sensing. Structurally, the JIS-standard riveted SUS304 stainless round-body is notably shorter than an ISO 6432 cylinder of the same bore and stroke, providing a packaging advantage in compact fixtures.
