Airtac MF32-40 Stainless Steel Mini Cylinder MF32X140SCA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X140SCA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 140mm 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 MF32X140SCA
Delivering 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder features a SUS304 stainless barrel with riveted aluminium covers that resist mild corrosion and washdown. Because the MF body is shorter than an ISO 6432 cylinder for the same 32 mm bore and 140 mm stroke, it saves valuable mounting length in tight fixtures. The piston relies on a two-way oil-retaining seal for long life, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impact.
Equipped with a built-in magnet (-S) and a CA pivot back cover, it accepts CMSG, DMSG, or EMSG switches for position sensing. Plan for about 241 N of real work at 0.5 MPa, which means it lifts roughly 20.5 kg vertically with a 2:1 safety margin. The 1/4" port and M10x1.25 male rod thread ensure solid pneumatic and mechanical connections across the 30-800 mm/s speed range.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X140SCA Is Used
Pallet Diverter Gate
Uses the 402.2 N push force at 0.5 MPa to swing heavy cardboard cartons off a main packaging conveyor line onto a secondary sorting belt.
CNC Lathe Door Actuator
Leverages the JIS compact body and 140 mm stroke to open and close sliding safety doors in tight machine enclosures where ISO 6432 lengths will not fit.
Vertical Parts Lift
Raises small aluminum machining blanks weighing up to 20.5 kg out of a hopper, utilizing the CA pivot mount to accommodate slight angular misalignment.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X140SCA the Right Cylinder?
When sizing this 32 mm bore, compare it directly against its neighbours: the MF25 provides 245.3 N of push at 0.5 MPa, while the MF40 steps up to 628.3 N. If your fixture demands maximum compactness, remember this JIS body is physically shorter than a comparable ISO 6432 unit. The -S magnet enables CMSG, DMSG, and EMSG sensors, and the CA rear pivot simplifies angular mounting. For a 140 mm stroke, keep the load guided to prevent rod bending and side-load wear.
Note that the fixed TPU bumpers only decelerate the stroke end; they do not function as a brake. If air pressure drops or the valve is centred, the piston will drift and drop the load. To maintain vertical position during an outage, install an external rod lock or a pilot-operated check valve.
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 MF32X140SCA FAQ
At 0.5 MPa it pushes with 402.2 N and pulls with 345.6 N. At 0.7 MPa it pushes 563 N and pulls 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa. This 32 mm bore cylinder uses a 1/4" air port and an M10x1.25 male rod thread.
No, the fixed TPU bumper pads only decelerate the piston near the stroke end and act as an impact buffer, not a braking mechanism. If air is lost or the directional valve is centred, the piston will drift and drop the load. You must add an external rod lock or a pilot-operated check valve to hold a vertical load safely.
