Airtac MF32-40 Stainless Steel Mini Cylinder MF32X80CM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X80CM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 80mm 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 MF32X80CM
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore mini cylinder handles demanding 80 mm stroke tasks. It features a JIS-standard SUS304 stainless steel barrel with riveted aluminium covers. Because the body is physically shorter than an ISO 6432 cylinder of the same bore and stroke, it saves valuable mounting length in tight machinery. The construction resists mild corrosion and washdown, while a two-way oil-retaining piston seal ensures long service life.
This specific configuration uses a CM round-end rear cover and a 1/4" air port. Fixed TPU bumper pads soften the impact at stroke extremes, though they decelerate rather than provide adjustable cushioning. Plan for a safe working load of roughly 241 N, which is about 60 percent of the 0.5 MPa rating. Alternatively, it can vertically lift around 20.5 kg with a 2:1 safety margin. Note that this SKU lacks a magnet, so it cannot host CMSG, DMSG, or EMSG sensors without upgrading to an -S variant.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X80CM Is Used
Package Diverting
Pushes medium-weight cartons off a main conveyor belt using its 402.2 N push force at 0.5 MPa, fitting neatly into compact sorter frames.
Textile Loom Tensioning
Maintains tension on fabric guides with an 80 mm stroke, benefiting from the SUS304 stainless barrel in humid manufacturing environments.
Pallet Stopper Gate
Acts as a pneumatic stop for pallets entering a wrapping zone, utilizing the CM round-end cover for a robust rear pivot mount.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X80CM the Right Cylinder?
When sizing this actuator, compare its 402.2 N push force at 0.5 MPa against neighbouring bores. If your load is lighter, the MF25 provides 245.3 N; if you need more power, the MF40 yields 628.3 N. For mounting flexibility, the MF series supports LB foot, FA flange, SDB pivot, and TC trunnion brackets, while the CM round-end back cover on this unit suits rear clevis installations.
Because this is a standard double-acting cylinder, it will drift and cannot hold a load if air pressure drops or the valve is centred. The TPU bumpers only soften the end of stroke and act as neither a brake nor a lock. To suspend a load safely, install an external rod lock or a pilot-operated check valve. Furthermore, the 80 mm stroke lacks a magnetic piston, meaning position sensing is impossible on this exact SKU.
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 MF32X80CM FAQ
This 32 mm bore cylinder features a 1/4" air port and an M10x1.25 male rod thread. 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 pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. Additionally, it uses fixed TPU bumper pads to decelerate the stroke end, not an adjustable air cushion.
