Airtac MF32-40 Stainless Steel Mini Cylinder MF32X80SCA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X80SCA 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 MF32X80SCA
Delivering 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder is built for tight machinery. Because its SUS304 stainless steel barrel and riveted aluminium covers form a shorter physical envelope than a comparable ISO 6432 unit, you save valuable mounting length without sacrificing the 80 mm stroke. The 1/4" port and M10x1.25 male rod thread provide robust pneumatic and mechanical interfaces for heavier tooling.
The riveted rolling-packed structure resists mild corrosion and washdown environments, while the piston's heterogeneous two-way seal retains an oil film for long operational life. Fixed TPU bumper pads and a front-cover anti-impact pad work together to soften stroke-end impacts. For practical sizing, plan for a safe working load of roughly 241 N, which allows this actuator to lift about 20.5 kg vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X80SCA Is Used
Package Diverter Arm
Actuates a pivoting diverter gate on a packaging line, using the 402.2 N push force to reliably redirect heavy cartons at high speeds.
CNC Lathe Door Glide
Opens and closes a sliding safety enclosure on a CNC lathe, where the compact JIS body saves axial space along the machine bed.
Pallet Stopping Gate
Deploys a mechanical stop block to halt incoming pallets on a gravity roller conveyor, absorbing the impact with its built-in TPU pads.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X80SCA 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 included -S magnet enables direct mounting of CMSG, DMSG, or EMSG sensors for position detection. This specific SKU features a CA pivot back cover, making it ideal for clevis mounting where the actuator must articulate during travel.
Because the standard MF relies on fixed bumper pads rather than an adjustable air cushion, it cannot hold a load if air pressure drops or the valve is centred—the piston will drift. If your application requires vertical position holding, integrate an external rod lock or a pilot-operated check valve. Additionally, for the 80 mm stroke, ensure your load is guided to prevent rod bending under 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 MF32X80SCA FAQ
At 0.5 MPa, the push force is 402.2 N and the pull force is 345.6 N. At 0.7 MPa, push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa. This 32 mm bore cylinder uses a 1/4" air port.
The CA back cover is a pivot mount designed for clevis attachments, allowing the cylinder to swing during operation. At the stroke ends, fixed TPU bumper pads decelerate the piston to reduce impact, but they do not act as an adjustable air cushion or a locking brake.
