Airtac MF32-40 Stainless Steel Mini Cylinder MF40X40SUTC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X40SUTC is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 40mm 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 MF40X40SUTC
Delivering 628.3 N of push force at 0.5 MPa, this 40 mm bore double-acting mini cylinder is built around a SUS304 stainless barrel with riveted aluminium covers that resist mild corrosion and washdown. Because the JIS-standard round body is physically shorter than a comparable ISO 6432 unit for the same 40 mm stroke, it saves valuable mounting length in tight machinery. The piston relies on a two-way oil-retaining seal for long life, while fixed TPU bumper pads and a front-cover anti-impact pad absorb stroke-end shock.
For practical sizing, plan for about 377 N of real work at 0.5 MPa, which safely lifts roughly 32 kg vertically with a 2:1 margin. This SKU includes a built-in magnet for position sensing and uses a 1/4 inch port. If you need adjustable end-cushioning for high-speed cycles, consider the MFC variant instead of this base model.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X40SUTC Is Used
Package Diverting
Uses the 527.8 N pull force at 0.5 MPa to actuate a routing gate on a high-speed packaging conveyor, fitting neatly into the tight transfer gap.
Press Fit Station
Pushes small bearings into housings on an assembly line, relying on the 628.3 N extension force while the TC trunnion absorbs side-moment loads.
Pallet Stop Gate
Controls pallet flow in a washdown-prone dispatch zone, where the SUS304 stainless barrel prevents mild corrosion from ambient moisture.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X40SUTC the Right Cylinder?
When sizing this 40 mm bore, step down to the MF32 if your application only requires 402.2 N of push force at 0.5 MPa, as there is no larger standard MF bore available for higher loads. This specific configuration includes a U flat-end rear cover and a TC trunnion mount, which accommodates pivoting frameworks. The integrated -S magnet directly supports CMSG, DMSG, and EMSG electronic or reed switches.
Remember that fixed TPU bumpers only decelerate the stroke end; they do not act as a brake. If air pressure drops or the valve centers, the piston will drift and drop the load. To secure a vertical load safely, install an external rod lock or a pilot-operated check valve alongside this cylinder.
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 MF40X40SUTC FAQ
The 40 mm bore uses a 1/4 inch port and an M14x1.5 male rod thread. At 0.5 MPa it pushes 628.3 N and pulls 527.8 N. At 0.7 MPa it pushes 879.6 N and pulls 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
The JIS-standard round body is shorter than an ISO 6432 cylinder for the same 40 mm stroke, saving mounting length. The included -S magnet allows direct mounting of CMSG, DMSG, or EMSG switches for position detection.
