Airtac MF32-40 Stainless Steel Mini Cylinder MF32X700SU
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X700SU is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 700mm 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 MF32X700SU
Delivering 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles long 700 mm travel requirements. The 700 mm stroke exceeds the 500 mm standard maximum, making this specific unit a non-standard, made-to-order configuration. For the same bore and stroke, the MF body is notably shorter than an ISO 6432 cylinder, yielding a real packaging advantage in tight machinery. The SUS304 stainless steel barrel and riveted rolling-packed aluminium covers resist mild corrosion and washdown environments.
The piston relies on a heterogeneous two-way seal that retains an oil film for prolonged operational life, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impact. Equipped with a built-in magnet (-S) for CMSG, DMSG, or EMSG switches, it also features a U flat-end back cover. Operating pressure spans 0.15-1.0 MPa, and the 1/4" port feeds the 12 mm rod. Plan for roughly 241 N of actual work at 0.5 MPa, which translates to lifting about 20.5 kg vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X700SU Is Used
Long-Reach Diverting
Pushes packages across a wide sorting conveyor belt using the full 700 mm travel, leveraging the 402.2 N push force to redirect heavy cartons reliably.
Vertical Lift Gates
Raises and lowers access gates on automated storage shelving, where the U flat-end back cover mounts flush to the frame and the short JIS body saves axial space.
Textile Beam Indexing
Shifts large textile beams laterally between processing stations, utilizing the SUS304 stainless barrel to withstand humid manufacturing conditions.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X700SU the Right Cylinder?
When sizing this 32 mm bore, stepping down to the MF25 yields 245.3 N at 0.5 MPa, whereas stepping up to the MF40 provides 628.3 N. Because this unit features a 700 mm stroke, carefully evaluate side loads to prevent rod bending over that extended distance. The included -S magnet enables position sensing with CMSG, DMSG, or EMSG switches, and the U flat-end rear cover suits direct rear mounting.
Remember that a standard cylinder drifts if air pressure drops or the valve is centred, as the TPU pads only decelerate the stroke end rather than locking the piston. To maintain vertical position under load loss, 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 MF32X700SU FAQ
This 32 mm bore cylinder features a 1/4" port and a 12 mm rod. 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.
No, the piston will drift if air is lost or the valve is centred. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. To hold a vertical load, you must use an external rod lock or a pilot-operated check valve.
