Airtac MF32-40 Stainless Steel Mini Cylinder MF32X500SU
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X500SU is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 500mm 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 MF32X500SU
Delivering 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder is built for demanding 500 mm travel tasks. Because the MF body is physically shorter than a comparable ISO 6432 unit for the same bore and stroke, it saves valuable mounting length in tight machinery. The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments.
This specific SKU includes a built-in piston magnet for position sensing and features a flat-end U back cover. It uses fixed TPU bumper pads to decelerate the stroke end, rather than an adjustable air cushion. For practical sizing, plan for a safe working load of roughly 241 N, which means it can comfortably lift about 20.5 kg vertically with a 2:1 safety margin. The 1/4 inch port matches the 32 mm bore specification.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X500SU Is Used
Carton Pusher Diverter
Pushes heavy cardboard cartons across a transfer belt using the 402.2 N push force over the full 500 mm travel distance.
Pallet Layer Separator
Extracts individual product layers from storage racks where the compact JIS body length prevents fixture clashes.
Film Roll Feed Mechanism
Advances large packaging film rolls forward, relying on the flat-end U back cover for stable rear mounting.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X500SU the Right Cylinder?
When sizing this 32 mm bore unit, stepping down to the MF25 yields 245.3 N of push force at 0.5 MPa, while stepping up to the MF40 provides 628.3 N. This model represents a non-standard 500 mm stroke, meaning it is a made-to-order configuration that requires careful attention to rod-bending side loads over such a long extension. The -S suffix denotes the internal magnet required for CMSG, DMSG, or EMSG switches.
Note that a standard cylinder will drift and cannot hold a vertical load if air pressure drops or the valve is centred; the bumper pads only soften the end of stroke and act as neither a brake nor a lock. To maintain position, you must 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 MF32X500SU FAQ
This 32 mm bore double-acting cylinder uses a 1/4 inch port and an M10x1.25 male rod thread. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum force of 82 kgf at 1.0 MPa.
The base MF uses fixed TPU bumper pads to soften stroke-end impact and does not have an adjustable air cushion; for adjustable cushioning, look at the MFC variant. Because this SKU includes the -S magnet, you can mount CMSG, DMSG, or EMSG electronic or reed switches directly onto the SUS304 stainless steel barrel.
