Airtac MF32-40 Stainless Steel Mini Cylinder MF32X350SCATC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X350SCATC is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 350mm 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 MF32X350SCATC
Generating 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore mini cylinder handles mid-range automation tasks with a 350 mm stroke. The JIS-standard round-body design is physically shorter than a comparable ISO 6432 unit, saving valuable mounting length in tight machinery. Its SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown environments.
Equipped with a built-in piston magnet (-S) for CMSG, DMSG or EMSG switches, the unit feeds position signals directly to your PLC. For practical sizing, plan for about 241 N of real work at 0.5 MPa, which means it safely lifts roughly 20.5 kg vertically with a 2:1 margin. Fixed TPU bumper pads and a front-cover anti-impact pad soften the stroke-end impact, while the 1/4" port ensures adequate airflow for the 30-800 mm/s speed range.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X350SCATC Is Used
Package Diverting Gate
Actuates a routing flap on a 1200 mm wide parcel conveyor, using the 402.2 N thrust to push 15 kg cartons smoothly into the secondary sorting lane.
Textile Loom Tensioner
Travels 350 mm to position a yarn guide bar, maintaining consistent material tension while the SUS304 barrel withstands humid production environments.
Pallet Wrapper Film Clamp
Extends to grip stretch film carriages on automated packaging lines, relying on the TC trunnion mount to absorb angular stress during the 350 mm extension.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X350SCATC the Right Cylinder?
When sizing this 32 mm bore, compare it directly against its neighbours: step down to an MF25 for 245.3 N at 0.5 MPa if your payload is lighter, or move up to an MF40 for 628.3 N if you need extra thrust. This model includes a CA pivot back cover and a TC trunnion mounting accessory, giving you a hinged rear pivot ideal for accommodating slight misalignment on long 350 mm strokes. The male M10x1.25 rod thread provides a solid attachment point for your tooling.
Because this is a standard double-acting cylinder, it will drift and cannot hold a vertical load if air pressure drops or the valve is centred. The internal TPU pads only decelerate the piston near the stroke end rather than locking it. To prevent gravity from pulling a suspended load down, integrate an external pilot-operated check valve or a dedicated rod lock 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 MF32X350SCATC FAQ
At 0.5 MPa this 32 mm bore cylinder pushes with 402.2 N and pulls with 345.6 N. At 0.7 MPa the push increases to 563 N and the pull to 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa. It uses a 1/4" air port and an M10x1.25 male rod thread.
It does not conform to ISO 6432, though its JIS-standard round body is intentionally shorter than an ISO 6432 unit to save mounting space. Because this SKU includes the -S magnet, you can mount CMSG, DMSG or EMSG switches for position detection. It uses fixed TPU bumper pads to decelerate the stroke end, not an adjustable air cushion.
