Airtac MF32-40 Stainless Steel Mini Cylinder MF32X520CM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X520CM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 520mm 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 MF32X520CM
Generating 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles mid-weight automation tasks with ease. The 520 mm stroke is a non-standard, made-to-order length exceeding the 500 mm standard maximum, engineered for applications requiring extra reach. Its SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown, while the two-way oil-retaining piston seal ensures long-term lubrication. Featuring a 1/4" port and an M10x1.25 male rod thread, it integrates smoothly into existing 32 mm bore setups.
Because the MF body is inherently shorter than an ISO 6432 cylinder for the same bore and stroke, it provides a tangible packaging advantage in tight fixtures. For practical sizing, plan for about 241 N of real work at 0.5 MPa, which means it lifts about 20.5 kg vertically with a 2:1 safety margin. The stroke end is softened by fixed TPU bumper pads and a front-cover anti-impact pad, which decelerate the piston without offering adjustable cushioning. Note that this specific SKU lacks a magnet, so it cannot support CMSG, DMSG, or EMSG position switches without upgrading to the -S variant.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X520CM Is Used
Extended-Reach Diverting
Pushes packages across a wide conveyor belt junction using the full 520 mm stroke, applying 402.2 N of force to redirect heavy cartons reliably at 0.5 MPa.
Textile Loom Tensioning
Extends deep into a textile machine to position a tensioning bar, leveraging the SUS304 stainless barrel to withstand humid, lint-filled operating environments.
Vertical Parts Elevator
Lifts approximately 20.5 kg of stacked metal components to a second-tier machining cell, utilizing the 2:1 safety margin on the 0.5 MPa push force.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X520CM the Right Cylinder?
When sizing this actuator, compare it directly against its neighbours: the MF25 bore provides 245.3 N of push at 0.5 MPa, while the larger MF40 bore offers 628.3 N. If your fixture requires position feedback, you must select the -S magnet version, as this base model cannot accept a sensor. The CM round-end back cover provides a specific mounting interface for articulating rear pivot applications.
Because the 520 mm stroke exceeds the 500 mm standard limit, it is manufactured as a special order, and the extended rod length demands careful attention to side-load alignment to prevent premature bending. Furthermore, a standard double-acting cylinder drifts when air is removed or a valve is centred; the bumpers only soften the end of travel and act as neither a lock nor a brake. To suspend a load safely mid-stroke, incorporate 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 MF32X520CM FAQ
This 32 mm bore cylinder features a 1/4" port and an M10x1.25 male rod thread. It generates 402.2 N of push and 345.6 N of pull at 0.5 MPa, increasing to 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
This specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches; you must specify the -S variant for sensing. Regarding dimensions, the JIS-standard MF round body is physically shorter than an ISO 6432 cylinder for the same 32 mm bore and 520 mm stroke, saving valuable mounting length without conforming to the ISO interface.
