Airtac MF32-40 Stainless Steel Mini Cylinder MF32X275SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X275SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 275mm 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 MF32X275SCM
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore AirTAC mini cylinder is built around a SUS304 stainless steel barrel with riveted aluminium covers. The riveted rolling-packed structure shrinks the body length compared to an ISO 6432 cylinder of the same bore and stroke, saving valuable mounting space in tight fixtures. A CM round-end back cover equips the rear for pivot mounting.
The piston relies on a heterogeneous two-way seal that retains an oil film for extended mechanical life, while fixed TPU bumper pads and a front-cover anti-impact pad absorb stroke-end shock. Because the code includes an S, a built-in magnet enables CMSG, DMSG or EMSG position sensing. For practical actuation at 0.5 MPa, plan for roughly 241 N of usable work, which translates to safely lifting about 20.5 kg vertically against gravity.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X275SCM Is Used
Pallet Diverting Gate
Extends a 275 mm stroke to push medium-weight pallets onto a secondary packaging line, using the 402.2 N thrust to overcome carton friction.
CNC Lathe Door Indexer
Pivot-mounts via the CM round-end cover to swing a sliding safety door open and closed on automated turning centers.
Tote Stacking Arm
Lifts empty totes weighing up to 20.5 kg at a 2:1 safety margin, relying on the built-in magnet to confirm stack height via a DMSG sensor.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X275SCM the Right Cylinder?
When sizing this 32 mm bore, the adjacent MF25 generates 245.3 N of push at 0.5 MPa, whereas stepping up to the MF40 yields 628.3 N. The 275 mm stroke sits well within the 500 mm standard limit, though at this extension you should watch for rod-bending side loads and guide the payload to prevent binding. A 1/4" port supplies the air volume needed for stable motion.
Remember that the TPU pads only decelerate the end of travel; they do not function as a brake. If air pressure drops or the valve is centred, the rod will drift and drop the load. To maintain vertical position during an outage, install 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 MF32X275SCM FAQ
At 0.5 MPa it pushes with 402.2 N and pulls with 345.6 N. At 0.7 MPa the push is 563 N and the pull is 483.8 N. 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.
The MF is JIS-standard and is physically shorter than an ISO 6432 cylinder, so ISO brackets will not align. It uses fixed TPU bumper pads to decelerate the stroke end rather than an adjustable air cushion. For variable cushioning, look at the MFC variant.
