Airtac MF32-40 Stainless Steel Mini Cylinder MF32X350CM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X350CM 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 MF32X350CM
Generating 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles robust linear motion tasks. The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments, 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 32 mm bore and 350 mm stroke, it saves valuable mounting length in tight machinery.
Equipped with fixed TPU bumper pads and a front-cover anti-impact pad, the stroke end is softened but cannot be adjusted like an air cushion. For practical sizing, plan for roughly 241 N of real work at 0.5 MPa, which translates to lifting about 20.5 kg vertically with a 2:1 safety margin. This specific SKU features a CM round-end back cover and uses a 1/4 inch air port. It lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X350CM Is Used
Package Diverting Gate
Actuates a routing flap on a 350 mm stroke to redirect parcels weighing up to 20 kg on a packaging line, utilising the 402.2 N push force at 0.5 MPa.
Textile Loom Tensioner
Shifts a yarn guide carriage across a 350 mm path, benefiting from the SUS304 stainless barrel to resist humid textile mill environments.
Palletising Stopper Arm
Extends a physical stop barrier to halt incoming pallets, leveraging the compact JIS body length to fit within dense conveyor transfer zones.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X350CM the Right Cylinder?
When sizing this 32 mm bore unit against the family, the smaller MF25 provides 245.3 N of push at 0.5 MPa, while the larger MF40 yields 628.3 N at the same pressure. If your fixture requires position feedback, you must select the -S magnet variant, as this base model cannot host a reed switch. Furthermore, a plain pneumatic cylinder drifts when air is lost or the valve is centred; the bumper pads only decelerate the stroke end and act as neither a brake nor a lock. To suspend a vertical load safely, install an external rod lock or a pilot-operated check valve. With a 350 mm stroke, ensure your mounting arrangement—such as an LB foot or FA flange—prevents rod bending from excessive side loads.
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 MF32X350CM FAQ
This 32 mm bore cylinder features a 1/4 inch air port and an M10x1.25 male rod thread. At 0.5 MPa it pushes with 402.2 N and pulls with 345.6 N. At 0.7 MPa the push is 563 N and the pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, this specific SKU does not include a piston magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. It features a CM round-end back cover, and its JIS-standard riveted body is physically shorter than a comparable ISO 6432 cylinder, saving mounting length.
