Airtac MF32-40 Stainless Steel Mini Cylinder MF40X15SCA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X15SCA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 15mm 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 MF40X15SCA
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder is built for demanding short-stroke clamping tasks. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown, while the piston's two-way seal retains an oil film for extended mechanical life. Because the MF body is shorter than an ISO 6432 cylinder for the same 40 mm bore and 15 mm stroke, it saves valuable mounting length in compact machinery.
Equipped with a built-in magnet (-S) for CMSG, DMSG, or EMSG switches, this unit also features a CA pivot back cover for articulated mounting. Fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impact. For real-world actuation at 0.5 MPa, plan for about 377 N of usable work, which means it can safely lift a 32 kg vertical load with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X15SCA Is Used
Short-Stroke Clamping
Uses the 628.3 N push force to lock heavy cast iron engine blocks during CNC machining operations.
Pallet Arrestor
Stops 30 kg loaded pallets on a packaging line, relying on the compact 15 mm stroke to fit within tight side rails.
Articulated Gate Divertor
Pivots on the CA rear cover to swing heavy parcel routing gates on a high-speed logistics sorter.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X15SCA the Right Cylinder?
When sizing this 40 mm bore unit, dropping down to an MF32 reduces the 0.5 MPa push force to 402.2 N, while no larger MF bore exists above 40 mm. If your fixture requires the full 879.6 N output, simply raise the supply pressure to 0.7 MPa. The 1/4" port matches the bore size, and the male M14x1.5 rod thread handles heavy loads.
Remember that a standard cylinder drifts when air is lost or the valve is centred; the TPU bumpers only decelerate the stroke end and do not act as a brake. To suspend a load safely, install an external rod lock or a pilot-operated check valve. With a very short 15 mm stroke, side-load stress on the 16 mm rod is minimal, but ensure the CA pivot is aligned to prevent binding.
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 MF40X15SCA FAQ
This 40 mm bore cylinder features 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.
Yes to the sensor: the -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG switches. No to the cushion: this model uses fixed TPU bumper pads to decelerate the stroke end, not an adjustable air cushion. For adjustable cushioning, look at the MFC variant.
