Airtac MF32-40 Stainless Steel Mini Cylinder MF40X35SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X35SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 35mm 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 MF40X35SCM
Delivering 628.3 N of push force at 0.5 MPa, this 40 mm bore double-acting actuator handles heavy-duty positioning in compact spaces. The JIS-standard round-body construction is physically shorter than an ISO 6432 cylinder for the same 35 mm stroke, providing a tangible packaging advantage inside dense machinery. Because this SKU carries the -S suffix, it includes a built-in piston magnet for direct mounting of CMSG, DMSG, or EMSG reed and electronic sensors.
The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments. 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. Operating pressure spans 0.15-1.0 MPa, and the 1/4" port feeds the 16 mm rod. For practical sizing, plan for roughly 377 N of real work at 0.5 MPa, which means it can safely lift about 32 kg vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X35SCM Is Used
Press Pin Insertion
Drives dowel pins into aluminium jigs using its 628.3 N thrust, with the 35 mm stroke preventing overtravel and the CM rear pivot accommodating slight frame misalignment.
Heavy Package Divert
Pushes dense cartons off a sorting line; the short JIS body fits between tight conveyor frames while the SUS304 barrel withstands dusty warehouse environments.
Pallet Stopper Gate
Acts as a robust physical stop for incoming pallets, using the built-in -S magnet to trigger a DMSG sensor that confirms the gate is locked in position.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X35SCM the Right Cylinder?
When sizing this 40 mm bore unit, compare its 628.3 N push force at 0.5 MPa against the smaller MF32, which yields 402.2 N. Since 40 mm is the largest available MF bore, moving up in force requires switching to a different cylinder family. The CM round-end back cover suits rear pivot mounting, and you can pair the body with LB foot, FA flange, SDB pivot, or TC trunnion hardware. The 35 mm stroke keeps the rod short to minimize side-load bending, but always ensure the load moves linearly.
Note that a standard double-acting cylinder drifts when air pressure drops or the valve centres; the TPU bumpers only soften the end-of-stroke impact and do not function as a mechanical brake. To suspend a load safely during an emergency stop, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 MF40X35SCM FAQ
At 0.5 MPa it provides 628.3 N push and 527.8 N pull. At 0.7 MPa it provides 879.6 N push and 738.9 N pull. The theoretical maximum force is 128.1 kgf at 1.0 MPa. This 40 mm bore cylinder uses a 1/4" air port and a 16 mm piston rod with an M14x1.5 male thread.
This model uses fixed TPU bumper pads to decelerate the stroke end, not an adjustable air cushion; for variable cushioning you would need the MFC variant. However, because this SKU includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG switches for position detection.
