Airtac MF32-40 Stainless Steel Mini Cylinder MF32X240CA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X240CA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 240mm 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 MF32X240CA
Delivering 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder integrates a CA pivot back cover for articulated mounting. The SUS304 stainless-steel barrel and riveted aluminium covers resist mild corrosion and washdown environments. Because the riveted rolling-packed structure is inherently compact, the overall body is shorter than an ISO 6432 cylinder of the same 32 mm bore and 240 mm stroke, saving valuable mounting length in tight machinery.
The piston relies on a heterogeneous two-way seal that retains an oil film for long-term lubrication, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts without offering adjustable cushioning. Operating pressure spans 0.15-1.0 MPa, and the 1/4" port feeds a 12 mm rod with an M10x1.25 male thread. Plan for roughly 241 N of actual work at 0.5 MPa, which means it can safely lift about 20.5 kg vertically against gravity.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X240CA Is Used
Package Diverter Arm
Swings a sorting gate on a packaging line using the CA pivot mount, utilizing the 402.2 N push force to redirect moderate-weight cartons at high cycling rates.
Textile Loom Tensioner
Maintains consistent fabric tension via an articulated linkage, where the 240 mm stroke provides ample travel and the SUS304 barrel withstands humid operating conditions.
Pallet Stacking Pusher
Indexes lightweight components into a stacking fixture, benefiting from the short JIS body profile to fit within congested conveyor framework.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X240CA the Right Cylinder?
When sizing this 32 mm bore, stepping down to the MF25 yields 245.3 N of push force at 0.5 MPa, whereas stepping up to the MF40 provides 628.3 N. The 240 mm stroke is well within the 500 mm standard limit, but at this length side loads can induce rod bending; ensure the load is guided to prevent premature seal wear. The integrated CA pivot back cover suits articulated rod-end connections, but if your mechanism requires position feedback, note that this specific SKU lacks the -S magnet and cannot host CMSG, DMSG, or EMSG switches.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the directional valve is centred. The TPU bumpers only decelerate the piston near the stroke end and do not function as a braking device. To suspend a load safely during an emergency stop or air loss, fit an external pilot-operated check valve or a dedicated rod lock.
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 MF32X240CA FAQ
This 32 mm bore double-acting cylinder generates 402.2 N push and 345.6 N 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. It uses a 1/4" air port and a 12 mm rod with an M10x1.25 male thread.
No, this specific SKU does not include a piston magnet, so CMSG, DMSG, or EMSG switches cannot be used. You would need the MF32X240CA-S variant for sensing capabilities. The unit features a CA pivot back cover and fixed TPU bumper pads that decelerate the stroke end but do not provide adjustable air cushioning.
