Airtac MF32-40 Stainless Steel Mini Cylinder MF40X40UTC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X40UTC is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 40mm 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 MF40X40UTC
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder tackles heavier fixtures without demanding excessive mounting space. For the same bore and stroke, the riveted SUS304 stainless steel and aluminium build is noticeably shorter than an ISO 6432 unit, providing a tangible packaging advantage in tight machinery. The 1/4" port and M14x1.5 male rod thread handle the required air volume for robust actuation.
Inside, a heterogeneous two-way seal retains an oil film for long service life, while fixed TPU bumper pads and a front-cover anti-impact pad absorb stroke-end shock. Because the bumper only decelerates the piston, plan for roughly 377 N of actual work at 0.5 MPa, or expect it to lift about 32 kg vertically with a 2:1 safety margin. This specific configuration features a U flat-end back cover and a TC trunnion mount, but lacks a magnet, meaning it cannot host CMSG, DMSG, or EMSG sensors.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X40UTC Is Used
Press Fit Bushings
Drives small bronze bushings into gearbox housings on an automated assembly line, utilising the 628.3 N push force to seat components firmly.
Heavy Package Diverter
Acts as a heavy-duty diverter arm on a packaging conveyor, pushing dense cartons onto a secondary track using the TC trunnion mount to handle the pivot action.
Pallet Stop Gate
Functions as a robust stop gate at the end of a roller conveyor, securely halting loaded pallets prior to wrapping using the U flat-end rear cover.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X40UTC the Right Cylinder?
When sizing this 40 mm bore, verify if the smaller MF32 provides sufficient thrust at 402.2 N (0.5 MPa); since 40 mm is the largest available MF bore, there is no larger standard option to step up to if your application exceeds the 628.3 N rating. The TC trunnion mounting pairs with the U flat-end rear cover to support pivoting loads, though the short 40 mm stroke naturally limits rod bending and side-load stress. Remember that a standard cylinder drifts if air pressure drops or the valve is centred, so integrate an external rod lock or pilot-operated check valve if your assembly must hold a suspended load safely in place.
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 MF40X40UTC FAQ
At 0.5 MPa it pushes with 628.3 N and pulls with 527.8 N. At 0.7 MPa the push is 879.6 N and pull is 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa. This 40 mm bore cylinder uses a 1/4" air port.
No, this specific SKU lacks the internal magnet so it cannot accept CMSG, DMSG, or EMSG switches; you would need the -S variant for sensing. The body is a JIS-standard round-body design that is shorter than an ISO 6432 cylinder, featuring fixed TPU bumper pads rather than an adjustable air cushion.
