Airtac MF32-40 Stainless Steel Mini Cylinder MF40X100UTC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X100UTC 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 MF40X100UTC
Generating 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore mini cylinder handles heavy-duty positioning within tight machinery envelopes. Because the JIS-standard round body is physically shorter than a comparable ISO 6432 unit for the same 100 mm stroke, it saves valuable mounting length. 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.
Featuring a 1/4" port and an M14x1.5 male rod thread, the unit relies on fixed TPU bumper pads and a front-cover anti-impact pad to decelerate the stroke end. Plan for roughly 377 N of actual work at 0.5 MPa to maintain a safe margin, which translates to lifting about 32 kg vertically. This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG position switches.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X100UTC Is Used
Stamping Press Feeders
Pushes heavy metal blanks into a stamping die using its 628.3 N output, with the compact JIS body fitting neatly between press columns.
Pallet Diverters
Actuates a diverter arm to route loaded pallets on a packaging line, relying on the TC trunnion to absorb pivot stress during the 100 mm stroke.
Heavy Carton Lifters
Raises 30 kg cartons vertically using the 1/4" port air supply, staying within the safe 32 kg vertical lift margin calculated at 0.5 MPa.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X100UTC the Right Cylinder?
When sizing this 40 mm bore actuator, compare its 628.3 N push force at 0.5 MPa against the smaller MF32, which yields 402.2 N under the same pressure. Since 40 mm is the largest available bore in the MF series, moving higher requires an external rod lock or a pilot-operated check valve to prevent drift if air is lost, as the bumpers only soften the stroke end rather than locking the load. The included U flat-end back cover and TC trunnion mounting provide pivoting support to manage side loads during the 100 mm travel. If your assembly requires position feedback, you must select the -S magnet variant instead of this base model.
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 MF40X100UTC FAQ
This 40 mm bore cylinder features a 1/4" 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, with a theoretical maximum force of 128.1 kgf at 1.0 MPa.
Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG switches. Impact at the stroke end is softened by fixed TPU bumper pads and a front-cover anti-impact pad, which decelerate the piston without acting as an adjustable air cushion.
