Airtac MF32-40 Stainless Steel Mini Cylinder MF32X900CM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X900CM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 900mm 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 MF32X900CM
Delivering 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles substantial work within a compact footprint. Because the stroke of 900 mm exceeds the 500 mm standard maximum, the MF32X900CM is produced as a non-standard, made-to-order unit. Its SUS304 stainless-steel barrel and riveted rolling-packed aluminium covers naturally resist mild corrosion and washdown environments. Internally, a heterogeneous two-way seal retains an oil film for extended mechanical life.
For practical sizing, plan your fixture to handle about 241 N of real work at 0.5 MPa, which represents roughly sixty percent of the rated push. In vertical lifting scenarios, this translates to safely hoisting around 20.5 kg when applying a 2:1 safety margin. The unit features a 1/4" air port, a 12 mm rod, and a CM round-end back cover. Note that this specific SKU lacks a magnet; adding the -S option is required to utilize CMSG, DMSG, or EMSG sensors.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X900CM Is Used
Long-Reach Diverting
Pushes heavy cartons across a wide sorting conveyor using the full 900 mm travel, relying on the 402.2 N push force to overcome side friction without stalling.
High-Bay Ejection
Ejects packaged goods from the top tier of a palletizing machine, where the CM round-end cover pivots smoothly to accommodate minor alignment shifts.
Automated Coating Arm
Actuates a 900 mm spray arm across a washdown coating booth, benefiting from the SUS304 stainless barrel to resist moisture and chemical mist.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X900CM the Right Cylinder?
When sizing this 32 mm bore, the adjacent MF25 generates 245.3 N of push at 0.5 MPa, while the larger MF40 provides 628.3 N, giving you clear scaling steps if the load changes. At a 900 mm extension, the 12 mm piston rod is highly susceptible to side-loading and bending forces; ensure your guiding geometry is rigid and perfectly aligned to prevent premature seal wear. Fixed TPU bumper pads soften the impact at the stroke extremes but do not act as an adjustable air cushion.
Because this is a standard double-acting cylinder, it cannot hold a load in place if air pressure drops or the valve is centered—the piston will drift. If your application requires vertical position holding, you must integrate an external rod lock or a pilot-operated check valve into the 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 MF32X900CM FAQ
At 0.5 MPa it provides 402.2 N push and 345.6 N pull. At 0.7 MPa it provides 563 N push and 483.8 N pull. The theoretical maximum force is 82 kgf at 1.0 MPa. The air port is 1/4" and the male rod thread is M10x1.25.
This SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG switches without the -S option. Furthermore, the fixed TPU bumpers only decelerate the stroke end; they do not lock the piston. You must use an external pilot check valve to hold a suspended load.
