Airtac MF32-40 Stainless Steel Mini Cylinder MF32X80SUTC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X80SUTC 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 MF32X80SUTC
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore mini cylinder integrates a piston magnet, flat-end U back cover, and TC trunnion mounting. The JIS-standard round-body architecture is physically shorter than a comparable ISO 6432 unit for the same 80 mm stroke, yielding a measurable packaging advantage in dense machinery. Its SUS304 stainless barrel and riveted aluminium covers resist mild corrosion, while the internal two-way seal retains an oil film for prolonged operational life.
Equipped with fixed TPU bumper pads and a front-cover anti-impact pad, the stroke end is reliably decelerated without the complexity of adjustable cushions. For practical sizing, plan for a safe working load of roughly 241 N—about sixty percent of the 0.5 MPa rating—which translates to lifting a 20.5 kg mass vertically with a 2:1 safety margin. The 1/4" port and M10x1.25 male rod thread accommodate robust pneumatic flow and secure mechanical attachments.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X80SUTC Is Used
Package Diverting Gate
Actuates a routing flap on a packaging conveyor, using the 402.2 N push force to redirect cartons weighing up to 20 kg smoothly into secondary lanes.
CNC Lathe Door Indexing
Opens and closes a sliding safety guard on a CNC turning centre, where the compact JIS body saves valuable envelope space alongside the machine bed.
Parts Elevator Transfer
Lifts small metal billets between conveyor tiers, relying on the TC trunnion to accommodate slight angular shifts during the vertical 80 mm stroke.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X80SUTC the Right Cylinder?
When sizing this 32 mm bore, the adjacent MF25 generates 245.3 N at 0.5 MPa, whereas stepping up to the MF40 yields 628.3 N. Choose this model when your payload sits comfortably in the middle of that range. Because the included -S magnet supports CMSG, DMSG, and EMSG switches, position detection is fully enabled out of the box.
The TC trunnion mount pairs with the flat-end U back cover to handle pivoting loads, though an 80 mm stroke still requires careful rod alignment to prevent side-load bending. Remember that air pressure alone cannot secure a load; if the valve centres or supply drops, the piston will drift. To lock a vertical load in place, install an external rod lock or a pilot-operated check valve rather than relying on the bumper pads.
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 MF32X80SUTC FAQ
This 32 mm bore cylinder features a 1/4" port and generates 402.2 N push / 345.6 N pull at 0.5 MPa, and 563 N push / 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, the base MF uses fixed TPU bumper pads to decelerate the stroke end rather than an adjustable air cushion; for adjustable cushioning, look at the MFC variant. Additionally, it is a JIS-standard round body that is simply shorter than an ISO 6432 cylinder, not an ISO 6432 compliant unit.
