Airtac MF32-40 Stainless Steel Mini Cylinder MF32X80U
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X80U 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 MF32X80U
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MF32X80U is a JIS-standard round-body mini cylinder built for tight machinery layouts. Its SUS304 stainless barrel and riveted rolling-packed aluminium covers resist mild corrosion and washdown, while the piston's two-way seal retains an oil film for extended mechanical life. Because this 32 mm bore lacks the -S suffix, it cannot host CMSG, DMSG or EMSG magnetic sensors.
For the same 80 mm stroke, this unit occupies a shorter overall length than an ISO 6432 cylinder, providing a tangible packaging advantage. The 1/4" port drives a 12 mm rod, and fixed TPU bumper pads absorb end-of-stroke impacts. Plan for roughly 241 N of actual work at 0.5 MPa, which means it can safely lift about 20.5 kg vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X80U Is Used
Carton Diverting Gate
Actuates a routing flap on a packaging line, using its 402.2 N thrust to push corrugated boxes smoothly onto secondary tracks.
Clamp Actuation
Secures aluminium housings inside a CNC machining centre, where the compact JIS body length leaves room for multi-tool changers.
Pallet Stopper Arm
Functions as a pneumatic stop in a roller conveyor system, holding pallets steady for robotic wrapping at a safe working load of 241 N.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X80U the Right Cylinder?
If your fixture requires less thrust, step down to the MF25 which yields 245.3 N at 0.5 MPa; if you need more power, the MF40 provides 628.3 N at 0.5 MPa. This specific U-style configuration incorporates a flat-end rear cover, which suits direct mounting against flat plates. To support position feedback, you must select the -S magnet variant, as this base SKU cannot carry a switch.
Because standard double-acting operation allows the piston to drift if air pressure drops or the valve centres, do not rely on the TPU bumpers to hold a suspended load. An external rod lock or pilot-operated check valve is required for secure holding. Furthermore, at this 80 mm stroke, keep the load guided to prevent rod bending and premature seal wear.
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 MF32X80U FAQ
This 32 mm bore cylinder features a 1/4" port and a 12 mm rod. It 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.
No, the fixed TPU bumper pads only decelerate the stroke end and do not function as an adjustable air cushion or a locking brake. The piston will drift if air is lost, so an external rod lock is needed to hold a vertical load. Additionally, this model lacks a magnet and cannot support sensors.
