Airtac MF32-40 Stainless Steel Mini Cylinder MF32X350SCMLB
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X350SCMLB 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 MF32X350SCMLB
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore AirTAC mini cylinder tackles demanding 350 mm stroke tasks. It features a JIS-standard round-body design with a SUS304 stainless steel barrel and riveted aluminium covers. Because the MF body is physically shorter than an ISO 6432 cylinder for the exact same bore and stroke, it saves valuable mounting length in tight machinery. The 1/4 inch port and M10x1.25 male rod thread handle robust airflow and mounting.
For practical actuation, plan for a safe working load of roughly 241 N, which is about 60 percent of the 0.5 MPa rating. This translates to lifting a 20.5 kg part vertically with a 2:1 safety margin. 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 impacts. Since this SKU includes the -S magnet, it is fully ready for CMSG, DMSG, or EMSG position switches.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X350SCMLB Is Used
Carton Diverting
Pushes medium-weight packages along a packaging line using its 402.2 N thrust and 350 mm reach to clear the conveyor belt entirely.
Vertical Part Lifting
Raises 20 kg material bins between processing tiers, utilising the 2:1 safety margin derived from its 0.5 MPa push capacity.
Fixture Ejection
Ejects machined aluminium components from a tight-fitting jig where the JIS short-body design saves critical machine envelope length.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X350SCMLB 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 load is lighter, or step up to an MF40 for 628.3 N at 0.5 MPa if you need more thrust. This model includes a CM round-end back cover and an LB foot mounting bracket for stable base fixing. The 350 mm stroke falls within the 500 mm standard limit but is long enough that you must carefully manage side loads to prevent rod bending.
Remember that a standard cylinder drifts when air is removed or the valve is centred, as the TPU pads only decelerate the end of travel rather than locking the piston. To suspend a load safely mid-stroke, 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 MF32X350SCMLB FAQ
This 32 mm bore cylinder features a 1/4 inch port and generates 402.2 N push and 345.6 N pull at 0.5 MPa, or 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, the fixed TPU bumper pads only decelerate the stroke end and do not act as a brake; use an external rod lock to hold loads. It features a SUS304 stainless barrel, a CM round-end back cover, an LB foot mount, and a built-in magnet for CMSG or DMSG sensors.
