Airtac MF32-40 Stainless Steel Mini Cylinder MF32X275SCA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X275SCA 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 MF32X275SCA
Generating 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore mini cylinder handles substantial work within a compact footprint. The SUS304 stainless-steel barrel and riveted aluminium covers resist mild corrosion and washdown, while the piston's two-way seal retains an oil film for extended mechanical life. Because the MF body is shorter than a comparable ISO 6432 unit for the same 275 mm stroke, it fits tighter fixtures and saves valuable mounting length.
Equipped with a built-in magnet (-S) for CMSG, DMSG, or EMSG switches, this model also features a CA pivot back cover for articulated rear mounting. The 1/4" port drives a 12 mm rod, and fixed TPU bumper pads soften the stroke-end impact. For practical sizing, plan for about 241 N of real work at 0.5 MPa, which means it can safely lift a 20.5 kg part vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X275SCA Is Used
Package Diverting Arm
Swings a sorting gate on a packaging line using the 402.2 N push force and CA pivot mount to redirect cartons at high speed.
Vertical Pallet Lift
Raises a 20 kg layer of product using the 275 mm stroke, relying on the compact JIS body length to fit tight conveyor transfer zones.
Clamp Actuation
Secures aluminium extrusions in a machining fixture, where the SUS304 barrel withstands cutting fluid washdown and the magnet confirms clamp position.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X275SCA 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. If your process requires the rod to maintain its position during a loss of air or when a valve is centred, note that the piston will drift; the bumpers only decelerate the stroke end and do not act as a brake. An external rod lock or a pilot-operated check valve is required to hold a suspended load safely.
This specific SKU includes the -S magnet for position sensing and the CA rear pivot cover. The 275 mm stroke is within the 500 mm standard limit, though at this length you should ensure the load is guided to prevent rod bending and premature seal wear from side loads.
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 MF32X275SCA FAQ
This 32 mm bore double-acting cylinder uses a 1/4" port and an M10x1.25 male rod thread. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, or 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
The CA back cover provides a rear pivot point for articulated mounting. At the stroke ends, fixed TPU bumper pads decelerate the piston to reduce impact, but they do not provide adjustable cushioning. The JIS-standard round body is also physically shorter than an ISO 6432 cylinder of the same bore and stroke.
