Airtac MF32-40 Stainless Steel Mini Cylinder MF32X35SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X35SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm 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 MF32X35SCM
Delivering 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder integrates a built-in magnet and a CM round-end rear cover. The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown, while the piston's two-way seal retains an oil film for long service life. For the same 32 mm bore and 35 mm stroke, the MF body is notably shorter than an ISO 6432 cylinder, providing a tangible packaging advantage in tight fixtures.
The 1/4" air port and M10x1.25 male rod thread accommodate robust pneumatic supply and mounting. Fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impact by decelerating the piston, though they do not provide adjustable cushioning. Plan for roughly 241 N of actual work at 0.5 MPa, which translates to lifting about 20.5 kg vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X35SCM Is Used
Clamping Housings
Secures aluminium die-cast enclosures during CNC machining using the 402.2 N extend force, while the short 35 mm stroke keeps the fixture compact.
Carton Flap Folding
Folds corrugated cardboard flaps on continuous packaging lines where the JIS-standard short body prevents interference with moving conveyor belts.
Part Ejection
Pushes completed moulded plastic parts out of injection moulds, relying on the SUS304 barrel to withstand occasional coolant spray.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X35SCM the Right Cylinder?
When sizing this 32 mm bore, the smaller MF25 provides 245.3 N of push force at 0.5 MPa, whereas stepping up to the MF40 yields 628.3 N. This model hits a solid middle ground for moderate loads. Because the base MF lacks an adjustable air cushion, if your application involves high speeds you should evaluate the MFC variant. Furthermore, a plain cylinder drifts when air is lost or the valve is centred; the bumpers only decelerate the end of stroke and will not brake the load. To maintain position, specify an external rod lock or a pilot-operated check valve. The included -S magnet enables CMSG, DMSG, and EMSG switches for position sensing.
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 MF32X35SCM FAQ
This 32 mm bore cylinder features a 1/4" air port and generates 402.2 N push / 345.6 N pull at 0.5 MPa, and 563 N push / 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
The MF is a JIS-standard cylinder that is physically shorter than an ISO 6432 unit for the same bore and stroke, so ISO 6432 interfaces do not directly apply. However, the built-in -S magnet allows direct mounting of CMSG, DMSG, or EMSG switches for position detection.
